Thanks, it's working like a charm! I'll let you all know how it ends!
Anyway I wanted to ask one thing, since the project of replacing the Game Genie rom with TapeDump is dead (and I have a glob-top GG anyway), I was curious, what about cutting the current for the cartridge slot between cartridge exchanges? I can cut the lines and insert a switch to my Famicom, turn off the power to the cartridge slot when pulling out the TapeDump cart and powering it back on after the dumped cartridge is inserted. Would this work? I'm starting to worry about my Rockman multicart, since I already killed one glob-top pirate with the swap-trick.
Thanks!
Even if you did that I still wouldn't consider it "safe" in fact it might be worse. I'm not certain here but I'm imagining if damage is actually occurring it's because for a split second when pulling the cart you've broke contact with a power pin but some address/data pins are still connected. And in that situation normal power is removed but there is still the potential to power/ground some ICs through the address/data lines. and if you did that wonky things will happen and it's conceivable something could be improperly biased and burn out. I wouldn't think it's very likely but conceivable.
If my guess is correct you'd actually be making the issue worse by removing the Vcc for a few seconds vice a few milliseconds. But I'm not certain why your cart broke, it could have been coincidental and not related to hot swapping it, I'm only speculating really.
