Changing the grey Torizo facing animations during the standing part .

[Vener]

I think that all is in the title .

For things like that , Scyzer say to you :
1 - Change the wanted enemy index to 0 in a room (Done)
2 - Run the game in this room , with a write-check for the RAM adresse 7E:0F92 (Done)

I got this :

In this case , the pointer values in A (or Y) should lead me to the tilemap pointers , with the frames values to display it .
But those values doesn't lead me to tilemap pointers but in the middle of the tilemap pointer table (i'm almost sure) . So , where is my mistake ?

Also , i wonder if in the game , the programmers have made the reverse standing tilemaps of torizo , even if they have never used it . This could avoid to make all the new tilemaps , but it's a minor question .

I had this bank done like six months ago, sacrificed bomb torizo to the demon compendium for eight teleport torizo.
Lost all my notes though.

You definitely only need to search the first half of this bank.
The bottom half is dori, gold boss statues, maridia tube glass, & walking torizo statues.

There's this boss hex tweak doc that I started with to break into the bank.
The torizo share most of the routines, with region checks that decide what their AI will do.

I'll post whatever I can find today.

[PHOSPHOTiDYL]

Looks like $AAD745 & below is nothing torizo related.
There's also $28D5 bytes @ $AA87C7 I haven't identified.
Also $06D4 bytes @ $AAB279 & $08A8 bytes @ $AAB962.

I think you found what's @ $AAB279, it might be pointing to the mass @ $AA87C7...

[PHOSPHOTiDYL]

Here's what I got on bank $AA. Kept going til I found the sprites in that mess of code.
Still a lot of work to be done, though it should be easier now...

$AA8A96 - $AAA4E6.

[PHOSPHOTiDYL]

It looks like as soon as the sprites end are the structures for the spritemaps.
The pointers to the spritemaps are in them.

I think their structure might be...
dw $0001 ;//# of gfxmaps
dw $x-coord relative to enemy,$y-coord relative to enemy,$pointer to spritemap,$pointer to hitbox.

Those will be pointed to from somewhere else.

I'm sure the tilemap/tilemap pointers are in this , but the format look complexe

I finally flipped torizo for the standing part . It was painfull !
Of course , i had also to flip the crumbling chozo PLM , which was tankfully easy to do .
But a problem remain ; the falling bit tiles when PLM crumble , they have to be fliped also .

I looked into it :

Crumbling chozo PLM $D6EA:

I assume that the stuff at 03:254B is the 8 crumbling tiles that fall , considered as projectiles , but i don't understand where those Tiles are located in the ROM  >_< i checked the entire ROM in TLP . It may be the same CRE tiles that the static chozo befor breaking , but they look a bit different :C 

I hope someone has already stuffed to this ...
