Re: Megaman 4 minus infinity on Real Hardware wiring questio

I see.

I wasn't exactly sure because I know how to do the famicom ones but I have seen (and read) people do it on an NES cart using ETROM boards. Thought it might have been a more simple fit with that CHR ROM/RAM conversion. Ill do some more research, thanks!

Re: Megaman 4 minus infinity on Real Hardware wiring questio

I was trying to gather some information about this hack as well. The one thing i'm unsure of is that in the CHR Ram conversion you need to connect to the NES carts pin 56. But it seems for the ETROM boards there is no 56th pin (They have the 5 pin gap in the middle). Is he using the famicom cart?

Re: SGROM Wiring same as SNROM?

Well im an idiot. Turns out that even tho I was right about Bionic Commando and got the right donor, the translated version actually uses WRAM. So I found a bunch of SNROMs with no batteries that'll do that trick. But im also guessing if I did get one with a battery it wouldn't make a difference any...

Re: SGROM Wiring same as SNROM?

Thinking about it perhaps you're right about my Skate or Die! UNROM problem. Because the game'll start up but it keeps flashing random colors. Green, Blue, Purple, White etc. I'll take another glance at it. As for my SGROM, well its still a mystery to me. I thought i could get my hands on a multimet...

Re: SGROM Wiring same as SNROM?

The patch works in nestopia. As for the wiring, I don't have any tools to test. Im just meticulous with my soldering. I have already done a mmc3 game that worked that I did without testing. I have looked over the board and it seems fine but I will check with a multimeter. On the other hand it might ...

Re: SGROM Wiring same as SNROM?

Thanks for the help guys. I still can't quite figure out why this isn't working. Is there any more info I could give you guys that'll shed more light on this? OR is it i'm just not understanding something that's pretty simple? I used my Bionic Commando rom and patched it with this ips http://www.rom...

Re: SGROM Wiring same as SNROM?

Ah, I think that might be the problem. Its an AM27C020.

I have pin 24 grounded to pin 16, hole 1 to pin 30 and hole 24 to pin 2.

Re: SGROM Wiring same as SNROM?

My wiring is clean enough. Nothing jumping. Also the EPROM was verified. Cant get my head around this. Ive also read people with similar problems with no solution. Did I just not rewire correctly? Ill specify a little more and chalk it up to a learning experience. Im using the famicom rom of Bionic ...

Re: SGROM Wiring same as SNROM?

Oh I didn't know that existed. Thats awesome! But my problem is im using an SGROM game to make anothe SGROM game. Altho one is SGROM-02 and the other is SGROM-03. And the wiring I used was the SNROM wiring (Pin 1, 2, 24, 30, 31, 2-24H, 30-1H, 16-24)

Re: SGROM Wiring same as SNROM?

Bumping this as I just had the same problem. My wiring is totally fine. FWIW im using Tecmo Baseball as a donor for the translated Bionic Commando rom. There might be a difference because of the CHRAM but I dunno.

Re: AMROM to AOROM

Hrm... looks like i'll have to. Thanks! While we're on a similar topic, I was told that I can use an SGROM PCB board for SNROMs as long as I don't care for saving and using the battery. Is this true? I just wired up Maniac Mansion (SNROM) using Rad Racer (SGROM) and it's not working. I wired it usin...

AMROM to AOROM

Hey guys! Been lurking around here a bit grabbing some info here and there but I have one question I can't seem to find the answer to without directly asking. Im making some repros for my own pleasure and one of the games I wanna make uses an AMROM board (Nightmare on Elm St). Now my issue is not re...
