Re: Help needed: Rockman 6-in-1 multicart hardware
I've swaped megaman 1 with megaman 2. Now megaman 1 has audio distorsion and Megaman 2 has perfect audio. In this case for megaman1 i've used Farid's patch and for megaman 2 i've used Infidelity's patch.
Note: if i first start megaman 1, reset and start megaman 2, the game will also have audio distorsion.
Another test: megaman 1 and 2, both with infidelity's patch. Both have audio distorsion.

Re: Help needed: Rockman 6-in-1 multicart hardware
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 major factors that I need to tackle. Im fixing them, making progress.
Re: Help needed: Rockman 6-in-1 multicart hardware
Another test (i'm going crazy here).
I replaced Megaman 1,2,4,6 with castlevania mmc3. Castlevania works perfectly, no matter wich one i start.
Now i only replaced megaman 1,2 and 4 with Castlevania mmc3. Castlevania starts, but after the intro (when he enters the gate), i get a black screen, no matter wich game i select.
Next I replaced Megaman 1,2 and 6 with castlevania mmc3. Castlevania works perfectly, no matter wich one i start.
So, it's something wrong with my wiring or with the menu?

Re: Help needed: Rockman 6-in-1 multicart hardware
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 with something like this. I had to rewrite how $8000-$8001 read gaiden's chr setup. But when I try to have 2 sets of routines, the in-game palette fade in gets stuck in a weird loop, and the chr routine doesnt work. This is the only issue left with this game from becoming a full MMC3 port.
EDIT - Freak luck, I was able to get the text to appear for the cutscenes.
Now im still trying to decypher in-game co-existences of 2 chr setups, very difficult.
EDIT #2 - Making progress, found a workaround but it aint pretty looking code wise, but its being allowed to work and display. Hoping by tonight or tomorrow to have it finished.

Re: Help needed: Rockman 6-in-1 multicart hardware
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 Act III, (title screen, cutscenes, level layouts, mappings, etc) are all there and correct.
I do not have a tkrom board/multirom board, nor the proper tools for that, so I cant confirm if my patched work will work on those devices.
My MMC3 Package Now Updated To 4.0, Which Now Includes Ninja Gaiden Converted To MMC3, Along With Notes

I hope you all enjoy this, this really was more work than I expected! :-0

Re: Help needed: Rockman 6-in-1 multicart hardware
Workin on a guide on how I convert (specificly) towards MMC1 to MMC3, regarding CHR, and bankswapping.

@ infidelity
Well done, thank you!
Now it is possible to make the Ninja Gaiden Trilogy multicart!
Also thank you for the tips, that is really awesome.
Keep up the good work.

you could do it like on the SNES and put in some pictures if it is not too hard

Farid, have you made the ninja gaiden multicart?

Re: Help needed: Rockman 6-in-1 multicart hardware
So anyone got a PCB in the works for this as of yet?
Re: Help needed: Rockman 6-in-1 multicart hardware
I don't think there will ever be a PCB available because it's not cost effective.
The best way is to use adapters. TSOP and SO chips are not expensive and after that use wires.
I still didn't solved the audio issue in megaman 2. FARID teste it on a famiclone, maybe doesn't work right on an original nes, or maybe i did something wrong (i checked everything many times) or maybe the blame is on the 74 chips.
FARID said at one moment that had in mind a ninja gaiden trilogy. That will be easyer to build because each game has only 128k chr and 128k prg, so you can use 2x 29f040, dip32.

Re: Help needed: Rockman 6-in-1 multicart hardware
I don't understand how it wouldn't be cost effective as it's still gonna use the exact same amount of chips no matter what and you don't need to to use tsop adapters if you stick to a 27c160 in 8bit mode. It would just be nice to not have to make a rats nest of wires and chips to get it done is all and I believe this project to be popular enough that it would justify making a pcb for it.gorgyrip wrote:I don't think there will ever be a PCB available because it's not cost effective.

P.S. we can talk about it from 30 buck shipped(per one) in a run of 50. Bare PCB

^ I'd buy one. Just to make fixing my Rockman cart easier. Also, 80sFREAK is a good guy to work with. I've bought stuff from him via Famicom World.
