Hello cupcacus,
I was wondering how your flashcart project is going, any progress?
Maybe you could release a simpler version for the people who want to
give programming the vcs a try, emulators are nice for debugging but if
the downloading of the code is a few seconds it'll be much more fun to
test it on the real console. (Some simple bankswitching for extra rom would be nice though)
Maybe atariage could produce some PCB's for that device.
