So I have a working Columns board, and a non-working Columns 2. I put the Columns 2 EPROMs in my working Columns 1, and the game started up, but then when you try to enter a game, it crashes.
Any idea why it would boot on Columns 1 board but crash, and not boot at all on my columns 2 board?
edit: I found a document stating "The games on Sega C2 boards are protected by an Altair EPM5032DC (read protected) located at position 27.", I tried swapping the Columns 2 eproms AND the EPM5032DC to the working board, and it just boots up as a black screen. Do I maybe have a bad protection chip? Are the Altair protection chips keyed into certain games, or do they work on any Sega C-2 game?
Thanks guys!
