Memory

Quite a bit of the memory has not been figured out. The game also reuses memory blocks for different purposes. For some memory blocks, there is an ASCII "tag" at the start which helps hint at what the memory is for.

Player Memory Blocks

From 108110 to 10830f is a memory block for player 1, and 108310 to 10850f is player 2's block. They are 512 bytes each.

These blocks contain a starting "tag" in ASCII, that indicates what the block is currently being used for, where X is either '1' or '2' depending on the player

tag	use
PLAYERXI	set before a player has pressed start to start a game
PXSELECT	set after pressing start and during how to play
PX TEAM	set when the player is choosing their team
PXMEMBER	set when the player is choosing the player order
PLAYER X	set while the match is playing

"PLAYER X" is set throughout the entire match and win screen. It goes back to "PX TEAM" when choosing the next team to fight.

PX TEAM Memory Decoded

start	end (inclusive)	description
108110	108117	'P1 TEAM' in ascii
108235	108237	Character IDs of p1 chosen team

PLAYER X Decoded

the blocks are tagged "PLAYER 1" and "PLAYER 2" while playing the match

start	end (inclusive)	description
108110	108117	'PLAYER 1' in ascii
108231	108231	The team Id (see teamIds.md), example Italy is 5
108232	108234	The character ids in order of when they fight
108235	108237	Character IDs of p1 chosen team, in team order

MEMBDISP blocks

There are six blocks that each start with the tag "MEMBDISP"

Address	team	char
102910	p1	1
102B10	p1	2
102D10	p1	3
102f10	p2	1
103110	p2	2
103310	p2	3

Decoding

Team Italy used as an example

address	value	description
102928	000d19e8	Pointer into ROM of first character's tiles
10292c	0070	Same value for all teams, written once, never read
102930	0001	Same value for all teams, written once, never read
10296a	ffe0ff90	Never changes, but was diff in dumps???
102970	000f	The character, likely the only byte that matters
