Re: Need help with SRAM issue with Nestopia

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.

Re: Need help with SRAM issue with Nestopia

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...

Tetris hack needs help with SRAM issue with Nestopia

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...

Re: Need help with MMC5 PCM

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.

Re: Need help with MMC5 PCM

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.

Re: Need help with MMC5 PCM

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...

Re: Need help with MMC5 PCM

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...

Re: Need help with MMC5 PCM

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

Re: Need help with MMC5 PCM

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

Need help with MMC5 PCM

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 ...
