Last view: 4129 days 		I've made quite a bit of progress on this front, so I figured I'd share a snapshot of my work. There's still a whoooole lot to improve, especially the documentation (most of what's there comes from Sukasa and SmallHacker). But I figure the more eyes we get on this the better things will be. Hopefully this doesn't count as a ROM link -- here we go

Still friggin' amazing, though.

I see a few things that have incorrect labels/comments(specifically in b0.asm). I've corrected them below:

UploadSPCEngine:    LDA.B #$00                ; \ this address (0E:8000) is the start of the SPC engine/

                    STA.W $0000               ;  |instrument settings/sound effect data

                    LDA.B #$80                ;  |AND the code used for all music banks.

                    STA.W $0002               ; /
Labels I changed:
ADDR_0080E8 -- UploadSPCEngine
UploadMusicBank1 -- UploadSamples
UploadMusicBank2 -- UploadMusicBank1
ADDR_008148 -- UploadMusicBank2
ADDR_008159 -- UploadMusicBank3

PS: Where is the Throw block Sprite data's Animation and Character settings at?

So far, Great job!

Last view: 6054 days 		This is pretty amazing, having the raw code for the entire ROM sitting in front of me. I don't understand most of it, but I've been able to glean some choice pieces of data where stuff is clearly labeled. (Currently trying to sift through Bob-omb's code in hopes of figuring out how to stop the explosion timer from resetting when throwing it horizontally)

Last view: 4129 days 		I've been steadily making progress on the disassembly. I'd like to once again share the current progress with everyone here. You'll see that many more sections have been commented. Also most of the stored pointers now reference their targets. Have a look at the latest snapshot:
