I'd be more than happy to do it if I ever work out how to get these particular mappers to work. They look like simple extensions to MMC3. But, I can't seem to get them going for some reason.
Edit: One interesting thing that I discovered is that the Mapper 037 multicart menu copies some code to PRG RAM for execution when you make a menu selection:
Code:
SMB:
:0300:A9 03 LDA #$03
:0302:8D 00 60 STA $6000 = #$00
:0305:A9 80 LDA #$80
:0307:8D 01 A0 STA $A001 = #$2A
:030A:6C FC FF JMP ($FFFC) = $FF00
World Cup:
:0300:A9 04 LDA #$04
:0302:8D 00 60 STA $6000 = #$00
:0305:A9 80 LDA #$80
:0307:8D 01 A0 STA $A001 = #$2A
:030A:6C FC FF JMP ($FFFC) = $FF00
The only difference between the selections is the PRG ROM block number, which makes sense. Is it common for games to execute snippets like this out of RAM?
