Sherlock Holmes: Hakushaku Reijou Yuukai Jiken:Notes

Hello intrepid ROM hacker


script starts at 10410h (8400h-C000h in RAM)

ROM address=RAM address+8010

text routine: loads from RAM at 1C2C0 in ROM (C2B0 in RAM)

pointers are all over the damn place
digits are separated (1234512345 lllllmmmmm)
e.g. you'll often see pointer tables like: 84 ab f1 23 5e 08 08 08 09 09
(not necessarily in groups of 5 though)


Some pointer tables I found!
----------------------------
392B-3934 ROM (5)
B91B-B924 RAM
points to (ROM) 13B98-13BDB(end of script!)

137CF-137DE (ROM) (8)
points to (ROM) 1061C-106C7

137DF-137EE (ROM) (8)
points to (ROM) 106C8-10770

399C-39AB ROM (8)
B98C-B994 RAM
points to (ROM) 13DCC-13ECB(train prices)

B884-BA73 ROM (248)
B874-BA63 RAM
points to (ROM) 1077D-118CA (876D-98BA RAM)

BA74-BC63 ROM (248)
BA64-BC53 RAM
points to (ROM) 118CD-12C2C *then* 117CA-118CA (these last 8 are the same as the last 8 above???)

B97C-B984? RAM (points to 13DC8 ROM-a number, then 0000 pointers - seems to be prices)
B966-B96D? RAM (not working?)
B870-B87A? RAM
B7BF-B7C7? RAM
B7CF-B7D7? RAM

Some hardcoded pointers I found!
(first number is the pointer location in ROM. then the address it points to in RAM, then the address in ROM)

Parts of the script that still need their pointers located!
-----------------------------------------------------------
10424-1061B need pointers (21) starts at 1D246 ROM
118CB?
12C2D-137CE need pointers (100)
137CF-1380E is an inline pointer table (pointers+palettes?)
139E5-13ACE need pointers (7)
13D70-13DCB need pointers (23) (numbers)
13ECC-13F05 need pointers (16) (numbers)

hardcoded:
(I don't know what this means. More pointers? Figure it out)
----------
A9 (1) 8523A9 (2) 8524 search
A9 (1) 85C0A9 (2) 85C1 search

Some graphics in the ROM:
(only added here to better identify pointers that pointed to these places)
-------------------------
2679-2A78 (town names)
6010-700F (incl. title screen)
7810-800F
C010-FD0F
1015B-1039A (game over)
14010-1800F (incl. font)
