I'd really like to be able to erase/rewrite the original carts. Has any progress been made on this?
I read that SNK recalled a load of unsold carts to rewrite them and sell them as new in other regions. If thats true then surely there must be a way to unprotect the carts without cutting tracks to isolate the reset pin? If it works on the various chip manufacturers SNK used, it must be a pretty generic method?
Could this be a candidate - described here for the MX29LV081 flash chips,
