Has anyone homebrewed a ram cart? How much is possible, 24, 64, 256?!?!?! I was just wondering I believe it would e a really cool project to do.


You're limited to the A-bus CS0, CS1 and dummy regions which gives and address space of 56MB. The CS2 region (one megabyte) is reserved for the CD-ROM interface.
The CartDev card supposedly has up to like 32 megs of memory... so it can be done, if you can get hold of an edge connector that fits in the Saturn's slot...
