unebonnevie Posted July 18, 2021 Share Posted July 18, 2021 hi, I am trying to build a 64KB atari 2600 cart that uses a GAL to do bankswitching. The open source design is from GrandIdeaStudio.com. Here is the link to the schematic http://www.grandideastudio.com/wp-content/uploads/pp_atari2600_64k_schematic.pdf. The author also supplies the JED file to program the GAL. Has anyone tried out this design before? Is there like a menu driven program, obviously as a 4KB ROM itself, to help select the banks, thus, the games in a 64KB EPROM? Thanks!
