hey guys,
Thought I'd share what I've been working on for a while now....
I've made this SRAM adapter that will work on almost all the FX boards.... this is what I use to have multiple save banks for different games (i.e Star fox 2, or Yoshi's island, etc..) which I use in conjunction with my Mulit-FX boards. I have 2 Multi-Fx boards designs (not as cool as Ho-jo's though). 1st is just a 3 EPROM version that can have any of the FX games that are smaller than 8mbits. Switch on the side selects the games. The SRAM adapter keeps them all seperate. For example, you could have a Star Fox trilogy on the Stunt Race host (seen top of pic). The 2nd design can adapt Yoshi's Island into a 9 in 1 multi-Fx cartridge where All the FX games are in 1 cart. and the pic at the bottom is DOOM that also uses the SRAM adapter for saves and can also utilize the "rom board" that can have all 9 FX games on it.... each with it's own save space. I made the SRAM adapter so that it could be cut in half so it could be used on games, like stunt race, that already have a save circuit. All the "rom boards" that connect to the FX cartridge are re-flashable in circuit with standard programmers. The adapters are "edge Plated" so it makes it a little easier to solder it in place of the SRAM that it replaces. Geeze, this project has occupied way too much time and $$.
These could be used for FX development for those who need to test on real hardware without having to unsolder the roms.

EDIT: TOP PIC ---- I added pics of the "rom boards" which sit on the back side of the FX boards and can be removed to re-program if desired.
