Hi. I would like to know what memory types I have to buy for making my Last Bronx into a Sonic the Fighters/Championship (I would prefer the japanese version). I can't find all the information I need.
Hi. These 27c040 memories are 32pin? I have 27c400 40pin.What’s “to the max”?
those sound fast enough. If it doesn’t work you could try 90ns 27c040 but I think I have some model2 running 120ns 27c040
The 27c400 are like 27c4001, can they be useful?@Tailsnic Retroworks sorry, i was just typing quickly I guess, that's a mistake. you do need 40 pin for this. i have some 120ns 27c4002 I think i'm using currently and haven't seen any issues
So, for using the original jumpers sequence of Sonic Fighters I need those 27c4002 memories, right?well 27c400 is 40 pin, 27c4001 is 32 pin. There are like 3 'families' of chips that handles 4mbit unfortunately https://wiki.arcadeotaku.com/w/EPROM
you need the 40 pin variety with a pinout like 27c240/27c4002/27c4096 for the sound roms for Model 2. I don't think the 27c400 has that pinout despite being 40 pin and capable of 16 bit. There may be jumper settings you could use to get them supported but I don't know what those are, I think the jumpers are for that family.
alright, I have just ordered many Mm27c4002 from china. Many thanks a lot. All the rest of memories (322 and 160) are just flashed and socketed.Yes. I just converted a board TO last bronx and it was all 322’s, 160’s, and 4002’s. 240 and 4096 have the same pinout though so those work instead of the 4002
Hi. I have burnt all the 27c160, 27c322 and 27c4002, but all I have is garbage. I will continue the project when I have a 15-24khz bifreq screen. I will inform youYes.

I have set the jumpers like the image in this thread:have you changed the jumper settings?
Its mandatory. You can still hook it up to a 15khz monitor just to see if the games boot, it wont harm the monitor for just a few minutes
Good Also, be sure that you burnt the right eeprom type for the IC15 and IC16 (the main program), they need to be 27c4096 or 27c4002 (100/120NS).I have set the jumpers like the image in this thread:have you changed the jumper settings?
