The following article is a ROM map for Sindibad: Chitei no Daimakyuu.
Bank 00
Necessarily the core startup, also the controller input, text output, the audio driver / music engine, and odd (vestigial?) bits of code for running parts of the CD system and possibly debugging hardware.
- E000-E022: Reset handler, set up basic CPU state and memory
mappings (I/O and RAM to traditional locations, banks 1, 2, and 7
to $4000, $6000, and $C000, call out to set overscan color and
video mode, jump to $01.4A02.
- E023-E044: Transfer data from ($02) to video RAM at address in
$04-05, with length in $06-07. Sets the VDC state per $04-05,
writes in the address of the VDC data register in its place, sets
$01 to the TIA opcode, $08 to the RTS opcode, and JSRs to run the
resulting procedure.
- E045-E050: Transfer data from ($02) to ($04), with length in
$06-07. Sets $01 to the TII opcode, $08 to the RTS opcode, and
JSRs to run the resulting procedure.
- E051-E074: Transfer 32 ($20) bytes of data from address in YX to BG
palette at index in A. This is a single palette block.
- E075-E09A: Transfer 32 ($20) bytes of data from address in YX to
Sprite palette at index in A + 256 ($100). This is a single
palette block.
- E09B-E0A7: Write data in YX to BG palette at index in A.
- E0A8-E0B6: Write data in YX to Sprite palette at index in A + 256
($100).
- E0B7-E0C5: Zero out sprite palette entry $100 (set overscan to
black).
- E0C6-E0E5: Set video mode using register data at $E0E6-E109.
- E0E6-E109: Video mode register data. CR=$0008, RCR=BXR=BYR=0,
MWR=$0050, HSR=$0202, HDR=$041F, VPR=$0F02, VDW=$00EF, VCR=$0004,
DCR=$0010, DVSSR=$1000.

- E10A-E114: Clear Y (controller index), signal a possible
multi-tap (or six-button pad?) to reset its counter.
- E115-E12C: Select the D-pad bits for the current controller.
Burn a few cycles (seems excessive here?). Copy the current
controller state to the previous state. Read input from the
controller, shift it to the high nybble, and store it as the
current state.
- E12D-E13F: Select the button bits (I, II, SELECT, and RUN) for
the current controller. Burn a few (six?) cycles. Read input
from the controller, mask to just the low nybble, OR the D-pad
bits into the high nybble, invert the bits (apparently the
controllers are active-low), and store back to the current
controller state.
- E140-E148: Compute which controller inputs are "newly pressed"
since the last time they were read.
- E149-E14D: Loop back to $e115 until all of the controllers have
been read.
- E14E-E16B: For each controller (from zero to four), if the
corresponding bit of $1f is set, and the SELECT button is newly
pressed, and the current input state is just the RUN and SELECT
buttons being pressed, jump to $e000 (the reset entry point).
- E16C-E173: OR together the current input state of the first three
controllers and store the result as the input state for the first
controller.
- E174-E174: Return.

A lot of pointers to data blocks of various sorts, a lot of code pointers. Also appears to be the primary touchpoint for setting window geometry. At the same time, it doesn't seem to be used for the main game script (see $01.5b97) or for combat window geometry?

set up somewhere yet to be determined.
- 6173-6230: Window geometry records.
- Window geometry is a six-byte structure, though many of the
records are only four bytes long implying that the last two bytes
are either the same as the first two bytes of the following
structure or are overridden by some later process.
- The bytes are left-edge, top-edge, width, height, cursor
horizontal position, and cursor vertical position, in that order.

itself is only referenced from the "sell an item" entry of the
table at 6060), flags indicating than an item cannot be sold?
- 669C-66A6: ??? data ??
- Looks to be one byte for each of the first 11 items, a $00 if
they aren't particularly important to the plot, a $01 if they are
plot-relevant. Or perhaps some other semantic applies?
- Contextually (only one reference, from the routine at 6B82, which
itself is only referenced from the "drop an item" entry of the
table at 6060), flags indicating that an item cannot be dropped?

- 720C-7245: ??? external entry ??
- Builds a word array at $2f75 alternating #$1f and values from a
selected party member's inventory, then calls 7000 (to build up a
bitmap of which items are equipped?).

- 74D3-74D5: Clear A and jump to 74D8.
- Select a party member, with various special handling for
character $03 (Cherubim).
- 74D6-74D7: Set A to #$01 and fall through to 74D8.
- Select a party member, without special handling for character $03
(Cherubim), used purely for the "use an item" command at one
particular point in the process.
- 74D8-753F: Display and run party-member selection menu
- This routine has special hooks for the event that character id
$03 (Cherubim) is selected, both for general item use (Cherubim
cannot hold or use items) and for setting equipment (since the
equip command is the defined mechanism for showing per-character
stats).
- 74D8-74DA: Store A to $2fb0 (for-item-purpose flag?).
- 74DB-74DD: Call 71DD to ??
- Populate menu with a list of party members?
- 74DE-74EE: Set $2f6f to $2fa2 plus #$01 (??) and $2f6d to $2f70
minus #$02 (??).
- 74EF-74FF: Add $2fa2 times three to $2f6d.
- 7500-7508: Load $2f6d (??) plus #$01 into A and call 76F1 to open
the menu window, configure the interaction parameters, and render
the menu contents.
- 7509-750C: Clear A (as the initially-selected menu item) and call
77AE to run the menu interaction.
- 750D-750F: If the Z flag is clear (menu cancelled?), return.
- 7510-751D: Load the script tag for the selected menu item (a
character name in section $25), subtract #$1b (27, for Sinbad),
and store in $2fa6 (selected party member).
- 751E-7521: If the selected party member is not #$03 (Cherubim),
jump to 753F.
- 7522-752B: If the current command id is #$02 (equip items), call
6A32 to ??
- 752C-7534: If the value in A (the current command ID or the value
left by calling 6A32) is #$05 (cast magic, if it's the command
ID), or $2fb0 is nonzero (indicating non-item character
selection, see 74D6), jump to 753F.
- Preliminary investigation suggests that the return value from
6A32 may be a horizontal text cursor position, possibly meaning
a menu cursor position. The question is, can it ever be #$05?
Is it always #$05?
- 7535-7539: Call 76B0 to open a window displaying indexed message
#$0e (something about Cherubim not being able to hold items).
- 753A-753E: Set $2fa7 (??) to #$ff.
- 753F-753F: Return.

- 75DA-75E0: Turn background rendering on, sprite rendering off.
- 75E1-75F5: Opens a window and displays the party's current gold.
- 75E1-75E5: Call 7600 to open window 2, the gold status window.
- 75E6-75E8: Zero $2fa4. ??
- 75E9-75EB: Call 75F6 to ??
- 75EC-75F4: Set the horizontal cursor position to #$15 and call
76CB to display indexed message #$4b (the "G" prefix for gold).
- 75F5-75F5: Return.
- 75F6-75FF: Load $22a3.W (party gold) into YX and call 75A5 to
display it.
- 7600-7657: ??? Opens a new text window ?? external entry ??
- 7600-760B: Save A on the stack. If A is between $08 and $24
(inclusive), save a copy to $2fae.
- 760C-7617: Set $53 (window text tile high byte) to $02, if $2fad
is zero, call 7658 to ??
- 7618-7625: Restore and re-save A to the stack. Double it and use
it to index the pointer array at 6119, saving the resulting
pointer to $f7.W.
- 7626-763D: Copy out window border top-left corner coordinates and
width and height from the structure pointed to by $f7, and store
the next offset in the structure (four) to $2f6d.
- 763E-764A: Restore A from the stack. If it is zero, call EF0A to
animate displaying the text window, otherwise call ED1F to
display the text window without animation.
- 764B-7656: Reload the structure offset (four) from $2f6d, and
store the next two values in the structure to the text cursor
horizontal and vertical position.
- 7657-7657: Return.
- 7658-769A: Take a backup of the SAT (VRAM $1000-$10ff) at VRAM
$1100-$11ff (with a word of overrun?).
- 7658-7660: Select VDC MAWR (write address), wait until VBlank is
detected (we're about to do some DMA, which is triggered at the
start of VBlank, so we're waiting until we have most of a frame
to do the setup).
- 7661-7662: Clear X and Y indices.
- 7663-7677: Set VDC register index, data low, and data high from
$769b[Y++].
- 7678-767B: If fewer than five VDC registers have been set, branch
to 7663.
- 767C-7680: Increment X. If the result is one, branch to 768B.
- 7681-7684: If fewer than seven VDC registers have been set,
branch to 7663.
- 7685-768A: Set $2fad to 1 and return.
- 768B-7693: Select VDC MAWR (write address), wait until VBlank is
detected (the VBlank detection was cleared at 7658-7660, so this
is the following VBlank, meaning that the configured DMA has been
triggered).
- 7694-7698: Increment X. If the result is two, branch to 768B to
wait for the following VBlank onset, meaning that the configured
DMA has definitely completed.
- 7699-769A: Branch to 7663 to deal with the final two VDC register
writes.
- 769B-76AF: VDC register/data values used by 7658.
- DCR=$0001 (increment source, increment destination, no SATB
transfer repeat, no IRQ for VRAM-VRAM transfer, IRQ for VRAM-SATB
transfer). Note that VDC IRQs are blocked at the CPU level.
- SOUR=$1000 (isn't this the SAT base address?).
- DESR=$1100 (???).
- LENR=$0100 (257 (!) words), triggers DMA for next VBlank period.
- DCR=$0003 (enable IRQ for VRAM-VRAM transfer). Either the
documentation here is wrong, or the programmers misunderstood how
the DMA mechanism in the VDC works.
- LENR=$0000 (1 word), triggers DMA for next VBlank period.
- DCR=$0011 (disable IRQ for VRAM-VRAM transfer, enable VRAM-SATB
transfer auto-repeat).
- 76B0-76CA: Displays a given message (index in A) in a newly-opened
suitable window.
- 76B0-76CA: Open window #$00 (shopkeeper dialogue, message speed,
menu-result), #$01 (password-entry message), or #$2a (???),
depending on the input parameter.
- #$4f <= A < #$52: #$2a
- Message $4f is "どれを けしますか？" (section 26, tag 22)
- Message $50 is "よろしいですか？" (section 26, tag 23)
- Message $51 is "どうしますか？" (section 26, tag 28)
- A < #$02: #$01
- Message $00 is asking for a password.
- Message $01 is saying that the password is invalid.
- default: #$00
- Fall through to 76CB.
- 76CB-76E1: Displays a given message (index in A) in the current
window.
- 76CB-76D6: If the input parameter is #$4a or #$4b, set the text
palette to 9 (tile highbyte #$92).
- 76D7-76DC: Call 76E2 to look up the message to display and 405A
to display it.
- 76DD-76E1: Set the text palette to 0 (tile highbyte #$02) and
return.
- 76E2-76F0: Source a script section and tag from the array at
$45.7000 (mapped at $9000).
- A apparently should be <= #$62 (98) on entry.
- 76E2-76E3: Shift A left once and transfer to X.
- 76E4-76E7: Map bank $45 to $8000-$9fff.
- 76E8-76F0: Load $9000[X].W to YX and return.
- 76F1-773C: Open menu window and configure cursor behavior.
- Parameter in A, used to index 63AB.
- Menu #$21 (?) is handled specially, the window doesn't get opened and
the text palette doesn't get set.
- 773D-7787: Render menu window contents.
- Also sets the initial cursor position, from 638D.
- 7788-77A9: ??? display equipment type character before a menu text
entry ??
- 77AA-77AD: ??? equipment type character/tile codes ??
- 77AE-78FF: Non-combat menu interaction driver.
- 77AE-77B4: ??? variable initialization ??
- 77B5-77BB: Loop calling E10A to read the controllers until no
buttons are pressed.
- 77BC-77C1: Set $2c44.W to zero.
- 77C2-77D2: Increment $2c44.W by one.
- 77D3-77DC: If $2c45 AND #$08 is zero, call $12.75a3 ?? (blink cursor?)
- 77DD-77E6: If $2c45 AND #$08 is non-zero, call $12.75a9 ?? (blink cursor?)
- 77E7-7815: Call E10A to read the controllers, and then dispatch
on the input status.
- If UP is pressed, jump to 781B.
- If DOWN is pressed, jump to 7837.
- If LEFT is pressed, jump to 785A.
- If RIGHT is pressed, jump to 7894.
- If I is pressed, jump to 78D3.
- If II is pressed, jump to 78E9.
- If SELECT is pressed, jump to 78FA.
- Otherwise, jump to 77C2.
- 7816-781A: Call $12.75f2, then jump to 77BC. ??
- 781B-7826: Subtract the number of items per row of the menu from
the current item position. If it is less than zero, branch to
77C2, otherwise store the result back as the new current
position.
- This is the entry point for the UP-button handler.
- 7827-7829: Call $12.75a9. ??
- 782A-7831: Decrement the text cursor vertical position by the
vertical distance between menu rows.
- 7832-7836: Call $12.75a3, then jump to 7816. ??
- 7837-???
- This is the entry point for the DOWN-button handler.
- 785A-???
- This is the entry point for the LEFT-button handler.
- 7894-???
- This is the entry point for the RIGHT-button handler.
- 78D3-78E8: Send a command to the audio driver (??), call $12.75a3
(??), loop calling E10A to read the controllers until no buttons
are pressed, load #$00 to A, and jump to 78F6.
- This is the I-button "accept menu action" handler.
- 78E9-78F5: Send a command to the audio driver (??), call $12.75a9
(??), then load #$01 to A. ??
- This is the II-button "cancel menu action" handler.
- 78F6-78F9: Store A in $2fa7 and return.
- 78FA-78FF: Call $45.7298, then jump to 77C2. ??
- This is the SELECT-button "describe item/spell" handler.
- 7900-7A40: Common handler for (most) non-combat commands, including
buying and selling.
- Contextually, this runs a party-member selection (in all but one
case), thence an item-selection (from the party-member inventory
in most cases, from a /shopkeeper inventory/ in the one case),
thence related follow-on. It's a fairly templated, but also
fairly nested, menuing system, including back-step transitions at
basically every point. It also manages to be the primary context
for quite a bit of otherwise-unknown code.
- 7900-7906: Double $2fa3 (command id) and store it in $2f9c
(command word index).
- 7907-7956: Step 1: party-member selection.
- 7907-7909: Zero $2fa1 (??).
- 790A-790E: If $2fa3 (command id) is zero (buy from shopkeeper),
jump to 7957.
- This skips the first party-member selection.
- 790F-7914: $2fa2 = $6052[$2fa3]; (??)
- This value is either $00 (sell an item) or $02 (everything
else). The value $ff is also in the table, but at index
zero, thus precluded by 790A-790E.
- Affects the party-member selection window, somehow? The $00
case puts the menu on the right side of the screen, the $02
case on the left.
- This, of course, may be purely correlation, rather than
causation.
- 7915-791A: Call 76B0 to open a window and display an indexed
message drawn from the table at 6059 indexed by $2fa3 (command
id).
- In all cases, this is some variant on "who is doing this?"
- 791B-791D: Call 74D3 to select a party member.
- 791E-7924: Dispatch on $2fa7 (menu action result). If it's
zero (accepted), jump to 7937. If it's negative (Cherubim
case), jump to 7929. Otherwise (canceled) fall through
to 7925.
- 7925-7928: Call 7A41 to ??, and return.
- Contextually, this is probably some sort of display cleanup.
- 7929-792F: If $2fa3 (command id) is not $02 (equip), jump
to 7907.
- Selecting Cherubim for equip has a special case in character
selection, so needs special cleanup?
- 7930-7936: Load #$22 to A, call 7A54 to ??, and jump to 7907.
- Does 7A54 clear the character status window?
- 7937-7941: If $2fa3 (command id) is neither #$04 (use item) nor
#$05 (use magic), jump to 7951.
- 7942-7944: Call 7134 to ??
- This loads the selected party member ID times #$20 (so, the
"is a member of the party" flag) to Y.
- 7945-7949: If $2200[Y] is not zero, jump to 7951.
- $2200 is the start of the party data area, which includes
both equipment and spell inventories for all characters.
- 794A-7950: Load #$5f to A, call 7B6C to ??, and jump to 7907.
- This is section 26, tag 43: "きを うしなっている".
- This is the "selected person is unconscious" case.
- 7951-7956: Copy $2fa6 (selected party member id) to $2f98 (??).
- 7957-7969: Step 2: Item/spell selection.
- 7957-7959: Call 7A5E to ??
- Contextually, this is an inventory (party member or shopkeeper,
item or spell) selection menu.
- 795A-7960: Dispatch on $2fa7 (menu action result). If it's
negative (inventory is empty?), jump to 7907. If it's zero
(accepted), jump to 796A. Otherwise (cancelled) fall through
to 7961.
- 7961-7963: Call 7A41 to ??.
- From context, this is probably some sort of display cleanup.
- 7964-7969: If $2fa3 (command id) is not zero (buy from
shopkeeper), jump to 7907. Otherwise, return.
- 796A-799F: Step 3: Item/spell selection validity testing.
- 796A-796F: Copy $2c46 (selected menu item) to $2f97 (??).
- 7970-797E: Set $2f9a.W to ($6060[$2f9c]).W (??).
- This is looking up a function pointer in the table at $6060,
indexed by command id.
- 797F-7981: Call 7A5B to ??
- 7A5B turns out to be a JMP ($2F9A), making this entire sequence
from 7970 an indexed function call drawn from the table at
$6060, indexed by the current command id.
- 7982-7983: If the Z flag is set (??), jump to 79A0.
- This appears to be the /only/ use of a "result" from a function
in the table at $6060, though it doesn't rule out possible
side-effects.
- And it turns out that a number of these functions also set
$2fa7 (menu action result).
- 7984-7992: Set $2f9a.W to ($6075[$2f9c]).W (??).
- This is looking up a function pointer in the table at $6075,
indexed by command id.
- 7993-799A: Load $606e[$2fa3] into A. Jump to 79A0 if it is
negative.
- That is, if the command is $03, "give"... Which it can't be,
because the corresponding entry in $6060[] is 70A4, which
clears A and $2fa7, which in turn sets the Z flag tested
at 7982.
- Otherwise, this appears to be an indexed message ID,
contextually saying that the selection was invalid and
leading back to the inventory selection menu.
- 799B-799F: Call 7A5B to ??, then jump to 7957.
- As mentioned earlier, this is an indirect function call through
$2f9a.W.
- 79A0-???: Step 4: ???
- 79A0-79AE: Set $2f9a.W to ($608a[$2f9c]).W (??)
- Usual pattern for setting up an indexed call.
- 79AF-79B6: Load $6083[$2fa3] into A. Jump to 79BA if it is
negative.
- 79B7-79B9: Call 7A5B to ??
- 79BA-79C4: If $2fa3 (command id) is not $04 or $05, jump to 79D6.
- 79C5-79C9: If $2f9d (??) is non-zero, jump to 7A14.
- 79CA-79D5: Copy $2fa6 (selected party member) to $2f98 and $2c46
(selected menu item) to $2f97 (??).
- 79D6-79E4: Set $2f9a.W to ($6098[$2f9c]).W (??)
- Usual pattern for setting up an indexed call.
- 79E5-79EC: Load $60a6[$2fa3] into A. Jump to 7A14 if it is
negative.
- 79ED-79EF: Store A into $2fa2 (??)
- 79F0-79F2: Call 7A5B to ??
- 79F3-79FD: If $2fa3 is $01 (sell an item), load #$16 into A (??)
and jump to 7A04.
- 79FE-7A03: If $2fa3 is not $06 (drop an item), jump to 7A07.
- 7A02-7A03: Load #$21 into A (??)
- 7A04-7A06: Call 7A5B to ??
- 7A07-7A13: Dispatch on $2fa7 (??). If it's negative, jump to
79A0. If it's non-zero, call 7A41 to ?? and jump to 7907.
Otherwise, fall through to 7A14.
- 7A14-7A22: Set $2f9a.W to ($60ad[$2f9c]).W (??)
- Usual pattern for setting up an indexed call.
- 7A23-7A25: Call 7A5B to ??
- 7A26-7A30: If $2fa7 is non-zero, call 7A41 to ?? and jump to
79A0.
- 7A31-7A3A: If $2fa3 (command id) is $02 (equip), jump to 7957.
- 7A3B-7A40: Call 7A41 to ?? and jump to 7907.
- 7A41-7A53: ??? external entry ??
- Close/erase last window opened, preserving text cursor position?
- 7A54-7A5A: ???
- Close/erase window with ID in A, with some behavior controlled by
global variables?
- 7A5B-7A5D: ??? Indirect jump through $2f9a ??
- 7A5E-7B03: ???
- 7B04-7B16: ???
- 7B17-7B6B: ??? external entry ??
- 7B6C-7B93: ???
- Parameter in A. Indexed message, maybe?
- 7B6C-7B71: Push A to the stack, call 7600 to open indexed window
#$00.
- 7B72-7B7B: Pop and re-push A from the stack. If it is neither
#$3A nor #$58, jump to 7B84.
- $3a: section 25, tag 89: "つかえません".
- $58: section 26, tag 9: "すてられません".
- 7B7C-7B83: Load $2fa5 (selected item id) to A, call 7C1E to
display the selected item or spell name, and jump to 7B8A.
- 7B84-7B89: Load $2fa6 (selected party member id) to A and call
7C37 to display the character name.
- 7B8A-7B8E: Call 76CB to display indexed message #$2A.
- This turns out to be section 25, tag 83: "は ".
- 7B8F-7B93: Pop A from the stack, call 7B94 to ??, and return.
- 7B94-7B96: ??? falls through to 7B97 ??
- Call 76CB to display indexed message in A, and fall through to
7B97.
- 7B97-7B9C: ??? displays indexed message #$18 ??
- Call 76CB to display indexed message #$18 and return.
- This turns out to be section 25, tag 60: WFI.
- 7B9D-7BA1: ??? jumps to 7B97 ??
- 7BA2-7BDC: ???
- 7BDD-7BED: ??? falls through to 7BEE ??

#$05 (cast magic) jump to 7C2C.
- 7C26-7C2B: Load #$1f (script section 31, items) into Y, call 405A
(a trampoline) to display the item name, and return.

- Column 10 ($a), rows 2-5 are all three-character command
names, rather than single-character entries, so this prevents
the cursor from overwriting the middle characters in the
commands or addressing the right half of the commands.
- A consequence of this desgin is that pressing RIGHT from one
of these commands will cause the cursor to be erased and
re-drawn in the same location, while pressing RIGHT from the
last character in the first two rows will not. At worst,
this would manifest as a single-frame flicker in the cursor,
and this may be masked by other effects.

Largely unexplored, appears to be entirely data, definitely contains palette data.
- 8000-8BFF: ?? Monster data (96/$60 records, 32/$20 bytes each, see
$02.7491) ??
- These are four sets of four words, all encoded sprite pattern and
attribute data. Bits 0-10 (mask $07ff) are pattern id / address,
bit 10 is also Y-flip (and if it's set, pushes the pattern
address off the end of VRAM?), bit 11 is X-flip, bits 12-15 are
palette id.
- These are four rows of four elements of 16x16 tiles.
Left-to-right, top-to-bottom.

- 90F8-9137: ?? World map encounter table IDs (see $02.757b) ??
- The 256x256 position world map is subdivided into 8x8 zones,
represented here as eight rows of eight columns, each containing
a byte of data.
- Values attested are 0, 2, 3, 5, 6, 7, 8, and 9.
- 9138-???: Dungeon/cave encounter table IDs (see $02.757b) ??
- The first four values are 1, 4, $0a, and $0b. Subsequent values
fail to fit within the space available for encounter tables at
9080, suggesting that this region is 9138-913B, and a new region
