So I'm the process of creating custom sprites for Earthbound. I have one of the 4 main character replacements done. Once I'm done, I'm replacing the original rom sprites with mine and making a few minor tweaks. Once I've got the rom customized, I'd like to write it to a eeprom and install it in a cartridge to give to my best friend as a gift.
I know the original Earthbound uses the SHVC-1J3M-20 revision board. NHL 97 seems like a good donor board accordingly, but it's not the cheapest game. Can anyone recommend a cheaper game that can still do a clean install (just curious if I can save a few bucks since this could end up being an expensive gift once everything is made)? Any particular eeproms more suitable for this project?
Thanks for the help.
