Your issue with your CURRENT games has been solved. Just an FYI whenever you have ANY "memory" errors:
The OS is "uploading" the games firmware from the card into RAM or DRAM (graphics go one place, operations go another). Some code on the card is compressed. The processor transfers code in batches. it does a checksum of the batch, then verifies it. When the verify returns a mis-match, you've run out of RAM - and thus the error code at the address the transfer failed. (or you have a bad RAM card - it verifies the RAM card when the game boots - you can tell On the boot screen how much RAM it verified).
In other words, go to
www.newegg.com and order a 2gig SET of PC3200 DDR400 1Gig RAM sticks and install them in your 1gig MPU brain box, maximizing the potential of the MPU.
That will enable you to avoid any future "memory" problems with whatever games that Alpha 1 box will run. For example; if you're going to run Lightning Jackpots, you WILL need 2G's of RAM.
Hope this helps....
