I'd like to use a Doom cart to make a Star Fox 2 beta, to play on the real deal, but I can't seem to figure out the pinout.
Its a 40 pin SOIC mask rom, and it doesn't seem to be standard (unless I screwed up the wiring).
I know its not NES hardware, but I couldn't find any SNES hardware forums out there.
Thanks in advance,

Here's a pinout for the SNES cartridge connector:

You might be able to figure out the pins of the ROM chip using a multimeter and finding out what pins are connected to which lines on the cart connector.
Yeah, the problem is that the Super FX 2 chip sits between the SNES and the ROM.
I made a StarFox 2 cart recently using a Stunt Race FX cart as a donor. It has the advantage of having a battery for the save ram. Its fast enought to be reasonably playable.
The only real difference between a Saving SFX cart and a non savmin one is that there is the battery, a power supply switcher IC (to switch between the battery and main power) and a bypass cap for said IC.

I did not mean to be rude but you could get information quicker if you look for yourself and in the right place
Ah yes, that's for a 8Mbit 32 pin mask rom on a stunt race fx GSU-1 (super fx) cart.
I'd like to use a Doom cart since it uses the Super FX 2, which has two cores, and it might be faster. But unfortunately, its has a 40 pin mask rom, which I can only guess the pinout for. And was hoping someone might know here.
It doesn't really matter, you just have to connect 8mbit eprom, right ?
Anyway, I found it on my hdd, it comes from my old website.

I ruined a Yoshi's island the first time I tried. I think the superfx doesn't like to get too hot...
I am curious as to how this worked out for you. any notaseable difference from the 1?
Ok, Star Fox 2 (translated version) has no frame rate increase using GSU-2 (Doom cart) over GSU-1 (Stunt Race FX).
I've heard the GSU-2 (Super FX 2) has two cores, but it seems that Star Fox 2 doesn't use the other one.
Anyone else with these same findings?
I've heard that the only difference between SFX and SFX2 is that the SFX2 can address more ROM (32M vs 8M).
not sure but I believe it had two cores or something. However I doubt starfox 2 uses both or it wouldn't work on version 1.
I had some doubts about building sf2b on a gsu-1 as there were some rumors that it runs with greater fps rate on gsu-2, so I didn't even bother getting the gsu-1 to check it, and built it straight away on the gsu-2 pcb from Winter Gold (PAL only).
What I read back when the cherryroms board was still alive was d4s saying that translated version of the game didn't work properly on the gsu-2. It hangs up just before Nintendo logo appears if I remember correct.
The translated version I have seems to work fine on both GSU-1 and GSU-2.

I have not tried the other beta versions, but I will give them a shot.
There are 2 translated versions, a 'release' version with all the debug menus and displays disabled and a straight translation with all the debug stuff intact. Also the problem with running on a GSU-2 only affects Winter Gold carts.
I have that Japanese one with the frame counter, works alright for me, CRC32:1B3BC708.

Iam also searching for the 40pin maskrom pinout, but all old links are down.
Does anybody still have it maybe?
Thx
