Posted: Fri Oct 06, 2006 4:37 am Post subject: Super A'Can? |
|
|
I wonder if a circuit board for a Super A'Can cartridge could be developed? The pin spacing looks the same as the Master System, except it has one extra pin on each side. The layout of the board seems very logical and seems to use a 27c160 compatible rom. The only thing I don't understand is the purpose of the UM6650. I can't find any data on the chip.
I would like to have a socketed eprom cartridge to test out code on the Super A'Can. It would also be useful to dump the games to disassemble them.
Here's what I've found:
Code: |
Numbers are looking at the front of the cartridge with edge at bottom, numbered from left to right.
1F Ground?

Worst case you can probably at least take an old cart and make an EPROM cart out of it. Is the 6550 on all carts?
I remember grabbing a bunch of stuff off your FTP site back in the SNES heyday! |

I only have two, and both have the 6550. I just ordered the first cartridge made for the system, maybe that will have something different.
Those were the days. The SNES seems so complicated back then. _________________ Looking for a new game for the Genesis, SNES, Sega CD, Neo Geo CD, FM Towns, Philips CD-I, Atari Jaguar CD, TG-16/CD, X68000 or, CDTV/CD32?
