The bankswap isnt the issue, my routine works fine, the game wouldnt boot in anything if I did that incorrectly.

I just dont understand why its happening within nestopia. Nintendulator is just as picky as nestopia, but nintendulator is doing fine with my hack.

I used mmc3 so I could perform a bankswap routine, I was unable to do it within mmc1. Regardless of my player 2 functions being withn sram, sram isnt working within nestopia. I added the wram code at the beginning of the reset vector, and it just didnt do anything. So I dont know why this is happeni...

I hacked the nes version of Tetris, to uae SRAM for its score saving and loading. I also have some player 2 registers that reside within the SRAM. I modified the rom to use MMC3_118. Now my rom works on an actual RetroPak (needs already created .sav for SRAM, it works on Nintendulator, and the lates...

Just wanted to say, with the help of kuja killer, we were able to swap out $C000-FFFF, and I made it so links flying sword dpcm is loaded from the new bank, while the other dpcms are still able to be loaded from the original bank.

Yes I think im misphrasing. The sounds are DPCM, cause they cant be played anywhere else in the rom, only $C000-$FFF.

@snarfblam, I will definitly check out that wiki document. I purposely set aside 5, 4000 byte prg banks, for when the time comes for new asm.

Duplicate it to where? Certain functions will only work for me within $C000-$FFFF, particularly custom bankswap routines. Like if im in bank 04 and need to get into bank 30, I wiuld have to first load 30 jsr to the hw bank, perform my bankswap routine to bank 30, then when im done in there, I rts ba...

I dont understand. Ive always been under the impression, that $C000-$FFF was the hw bank, regardless of whatever mapper. I apologize for not knowing otherwise. But I believe ive found my answer, im pretty much screwed, because I need my code that I have in $C000 to stay there. Thanks for all the inf...

I originaly did use mmc3, but needed my prg to be set to 64x16kb, and the only way I could get my prg that maxed was to upgrade to mmc5. If there was a way for me to have stayed in mmc3, with the extra prg space I needed, I wouldve.

My 4000 byte banks go all the way to $100000

So you are saying the hard wired bank $C000-$FFFF can be swapped?

I have some questions regarding the PCM when it deals with the MMC5. Ive been working on a major overhaul of The Legend of Zelda. I converted the rom from MMC1 to MMC5. Zelda uses $4010 & $4011 for the PCM sfx located at $C000-$FFFF. The sfx are Link's flying sword, dungeon doors, boss sfx. Ive had ...
