Title: Checksum error with mk6 expansion board
Post by: eldee99 on November 26, 2017, 01:06:04 PM

Hi everybody,


I'm trying to use an mk6 expansion board, so I can run 8+ rom games. However, I get AVL main checksum error during bootup. 6 chip games work, but for example 4 or 8 chip games won't work. I am sure all chips are OK. It has to be something with the board. And experiences with this issue? Thanks!

Any dirt/dust/corrosion on the pins or sockets etc? It's strange to hear that a 4 chip game failed to load when a 6 chip game worked when they use the same sockets.
