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?
2F  Unconnected
3F  Unconnected
4F  Unconnected
5F  Data 8. Pin  15 on rom.
6F  Data 9. Pin  17 on rom.
7F  Data 10. Pin 19 on rom.
8F  Data 11. Pin 21 on rom.
9F  Data 12. Pin 24 on rom.
10F Data 13. Pin 26 on rom.

15F Connected to jumper 2. 16M: jumper 1-2 open 32M: jumper 1-2 closed
16F Address 19. Pin 42 on rom.
17F Unknown, runs under rom. Probably Address 18. Pin 1 on rom.

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.
