If you move the mouse one pixel down, the value is #$01. If you move it up, it is #$81. The MSB tells the direction and the other bits tell the number of pixels moved, always as a positive.
This subroutine turns this into a real negative number (One pixel up = #$FF, two pixel up = #$FE), so it can be added more easily.

From FullSNES:
Mouse Sensitivity The Mouse Resolution is specified as "50 counts/inch (+/-10%)". There are three selectable Sensitivity (Threshold) settings: 0 - slow - linear fixed level (1:1) 1 - normal - exponential -?- levels (1:1 to ?:1) (?:1=smaller than 6:1) 2 - fast - exponential six levels (1:1 to 6:1) Setting 0 returns raw mickeys (so one must implement effects like double-speed threshold by software). Settings 1-2 can be used directly as screen-pixel offsets. To change the sensitivity (for port n=0 or n=1): [4016h]=01h ;set STB=1 dummy=[4016h+n] ;issue CLK pulse while STB=1 <-- increments the value, [4016h]=00h ;set STB=0 or wraps from 2 to 0 ;Thereafter, one should read the Sensitivity bits, typically like so: [4016h]=01h ;set STB=1 ;\another STB on/off, for invoking reading [4016h]=00h ;set STB=0 ;/(not sure if this part is required) for i=11 to 0, dummy=[4016h+n], next i ;skip first 12 bits for i=1 to 0, sensitivity.bit(i)=[4016h+n], next i ;read 2 sensitivity bits ;Repeat the above procedure until the desired sensitivity value is reached. Caution: According to Nintendo, the internal threshold factors aren't initialized until the change-sensitivty procedure is executed at least once (ie. after power-up, or after sensing a newly connected mouse, one MUST execute the change-sensitivity procedure, EVEN if the mouse does return the desired 2bit sensitivity code).

$80/951E Graphics Decompression directly to VRAM
This subroutine is to 80% commented. Since I do not plan to write compression/decompression Utility, I see no use in breaking my brain to fully understand every piece of its mechanisms.
Notes:
Transfers data directly to VRAM.
The data source address is stored in $78-$7A.
$7B Buffer for Loaded Compressed Data Byte.
$7D contains the VRAM destination (times two).
Compressed Data Byte = $FF - Exit Subroutine.
Bits 5-7 of the first Data Byte decide how to handle the other bits / the next byte(s)
%000x.xxxx The next byte gets stored alternating in $2118/9 and incremented after each storing, how often depends on bits 0-4 (#%0000.0000 transfers it one time, #%0001.1111 transfers it thirty-two times).
%001x.xxxx
The next byte gets stored alternating in $2118/9 unchanged, how often depends on bits 0-4 (#%0010.0000 transfers it one time, #%0011.1111 transfers it thirty-two times).
%010x.xxxx
The next two bytes get alternating stored in $2118/9 unchanged, how often depends on bits 0-4 (#%0100.0000 transfers one byte, #%0101.1111 transfers thirty-two). Note that the counter gets decremented every SINGLE byte transfered, not every byte duo; this way, with an uneven number, the first and the last byte are the same.
%011x.xxxx
The next bytes get stored alternating in $2118/9 unchanged, how many depends on bits 0-4 (#%0110.0000 transfers one byte, #%0111.1111 transfers thirty-two).
%100x.xxxx
Next two bytes are an offset. This subroutine repeats already decompressed data from there.
%101x.xxxx
Same as above, but Data Byte gets EORed with #$FF %110x.xxxx Next two bytes are an offset. This subroutine repeats already decompressed data from Offset - Y.
%111x.xxxx
Same as above, but Data Byte gets EORed with #$FF

When this subroutine gets called, Y contains the APU register destination (Y = #$0x ==> $214x). A is 8-bit, the active 8-bit (A) are the value store in that APU register, the inactive 8-bit (B) are for $2143.
The carry is used here as error flag. When it's set, something went wrong.

$80/C36D Transfer (fixed Set of) Data to Satellaview
This subroutine transfers data to the Satellaview via Serial Port 2.
First, it sends "08" and then "00" (maybe the "$08" says that there will come eight double-bytes in total?). Then it sends one byte with a counter value and one data byte from $C392. So the transfered data is:
08 00 00 xx 01 xx 02 xx 03 xx 04 xx 05 xx 06 xx (xx = data bytes from $80/C392)

$80/C3D6 Transfer Data to Satellaview via Serial I/O Port 2
From nocash's FullSNES document:
2198h Serial I/O Port 1 (R/W) 2199h Serial I/O Port 2 (R/W) These ports are basically 3-bit parallel ports, which can be used as three-wire serial ports (with clock, data.in, data.out lines) (by doing the "serial" transfer by software). Outgoing data must be written before toggling clock, incoming data can be read thereafter. 0 Clock (must be manually toggled per data bit) 1-5 Unknown/unused (should be 0) 6 Chip Select - For Port 1: 1=Select / For Port 2: 0=Select 7 Data (Write=Data.Out, Read=Data.in) (data-in is directly poll-able) Bits are transferred MSB first. Unknown which chips these ports are connected to. One port does most probably connect to the 64pin MN88821 chip (which should do have a serial port; assuming that it is a MN88831 variant). The other port <might> connect to the small 8pin SPR-BSA chip? Possible purposes might be configuration/calibration, Audio volume control, and Audio channel selection (assuming that the hardware can decode audio data and inject it to SNES Expansion Port sound inputs).
A contains a 16-bit value that gets transfered via Serial I/O Port 2 ($2199) to the Satellaview. The MSB gets transfered first.
As mentioned: A contains a 16-bit value, even though A has to be set to 8-bit-size before this Subroutine gets executed.

I am not entirely sure, but $02 is at least used as a flag (maybe for more):
First, it gets cleared (everything is fine). If something is wrong, it gets checked if it is clear. If it is, the backup from banks $13-15 gets transfered to $10-$12, its value gets incremented and the subroutine starts over. If something goes wrong again, the subroutine branches to a different path.
