Snake's Revenge NES Help
« on: February 05, 2020, 09:52:52 pm »
Before I release this hack, I need help on how to fix this one problem:

Original Mapper:



Look at the text box at the bottom. Everything here is fine.
-------------------------------------------------------------------
MMC5



Look at the text box at the bottom. I marked it with a yellow rectangel. I can't seem to know how to fix this.
-------------------------------------------------------------------
The code is in the CHR swapping with MMC5 equivalents here:

Code: [Select]
07:C3D3: A5 27     LDA $27 = #$00
 07:C3D5: 20 00 C4  JSR $C400
 07:C3D8: A5 28     LDA $28 = #$09
 07:C3DA: 4C E4 C3  JMP $C3E4
 07:C3DD: A9 0F     LDA #$0F
 07:C3DF: 20 00 C4  JSR $C400
 07:C3E2: A9 00     LDA #$00
 07:C3E4: 48        PHA
 07:C3E5: A9 01     LDA #$01
 07:C3E7: 85 24     STA $24 = #$01
 07:C3E9: 68        PLA
 07:C3EA: 8D 2B 51  STA $512B = #$00
 07:C3ED: 8D 27 51  STA $5127 = #$00
 07:C3F0: EA        NOP
 07:C3F1: EA        NOP
 07:C3F2: EA        NOP
 07:C3F3: EA        NOP
 07:C3F4: EA        NOP
 07:C3F5: EA        NOP
 07:C3F6: EA        NOP
 07:C3F7: EA        NOP
 07:C3F8: EA        NOP
 07:C3F9: EA        NOP
 07:C3FA: EA        NOP
 07:C3FB: EA        NOP
 07:C3FC: EA        NOP
 07:C3FD: 4C 57 C4  JMP $C457

I figure out how to fix this problem.

Edit:
Still working on this problem. If not, then I might release it then.

I thought I did something about this bug but still working on it. If not then I will release it with this one bug.

Well the only thing you can do is use one of the codes in a fixed bank to another bank or use some cool new features.
