Yes I use fceux debugger, emu version 2.2.1 im not getting into a debate on why im converting roms to mmc3, its a new personal challange is all it is. Im moving on, not bothering with it anymore. Edit - Actualy I took the cheap way out. I bypassed the ufo sequence, and I have the rom jump straight t...

This is my custom chr engine asm i wrote up, which is to preserve the original mmc1 chr values loaded by Fester's Quest, and then converted to the proper mmc3 chr values. I've done this was about 5 mmc1 roms with no issues, it's just that this rom is set up specificly for vertical mirroring for the ...

I have a 20 byte chr pointer table. Values range from 00,04,08,0C,10,etc, up to 7C.

I increased the values through the table by 80. The ppu shows the correct gfx, but the nametable switches to Single Screen (Table 1) not to Vertical mirroring.

I have "A980 8D0080 A93C 8D0180 8D0180 8D0180 8D0180 60" but I see no change, I also tried 00-FF for 8D0180 and still no change.

Ive converted Fester's Quest from MMC1 to MMC3_118. The gameplay requires 1 screen mirroring, so thats whyi had to switch to 118, cause mmc3 lacks that mirroring type. The problem im having, is that im unable to force vertical mirroring within 118, which the pre-title screen requires to be drawn pro...

Workin on a guide on how I convert (specificly) towards MMC1 to MMC3, regarding CHR, and bankswapping.

Ok, I have Ninja Gaiden working as MMC3. Tested and working on the following emulators. FCEUX Nestopia Nintendulator (with some shaking issues. Can others please confirm?) Also tested and working on my RetroPak for my NES. Ive only played up to Act III on all devices. But everything leading up to Ac...

Ninja Gaiden MMC3 is about 95% complete. Need to figure how to have the text for both the cutscenes and the in-game hud, to display correctly. The text shows up as whatever tiles are stored currently in the ppu, they get fetched from somewhere else in the rom. Its been a long time since ive worked w...

Just wanted to give an update on Ninja Gaiden to mmc3. Progress is slowly coming along. This conversion has proved to be more difficult than all the rest. Ill give a more thorough explaination when I get the chance, but what I can tell you is that rom does boot up as mmc3, but chr/mirroring are 2 ma...

gorgyrip, please check acmlm board. Ive updated all my unrom to mmc3 patches with proper mirroring setups. I think its all set.

Also, Metroid has been added to my mmc3 coverted patch set.

-infidelity

Id say insert that code within the reset vector.

"A900 8D0140 8D0540"

If you are unable to do this, I might have time tonight to insert into mm2, and send you the patch to see if that fixes the sound issue on your multicart.

So the mm2 audio issue is not present on the tgrom board, am I reading that right? Working on Metroid MMC3 conversion today. UPDATE - I now have Metroid converted to mmc3. Boots/plays on FCEUX, Nestopia, Nintendulator, and on a real nes. I will now attempt converting Ninja Gaiden to mmc3. Hoping I c...

Ooooh, Ninja Gaiden, I love that game. Tonight ill take a look at that one. If you look at my notes for the mmc1 games I converted, it should give you some what of a template/idea of what to do. Basicly I first start by changing the mapper to mmc3 with "neshead" Then I find where the mmc1 ...

gorgyrip, please check my thread back in acmlm, I fixed my megaman 2 patch, along with megaman, contra, castlevania, duck tales, legend of zelda.

Ok, i have given up on any kind of mapper based irq. I've had no luck getting it going. It also seems Zelda lacks any kind of usage for $FFFE-$FFFF, cause that interupt was never being activated. I've noticed the MMC3 Megaman games, have some sort of "Thread" (i'm going by what i read in M...
