mapper 30 and yes you will he able to use it on an everdrive :)
Just wondering what is so special about mapper 30? I know a lot of homebrew games use it but why not mapper 4? At least mapper 4 (tkrom) can be put on a real cart like Kirby... unless it's the mmc thing. Mapper 30 will only work if you have nes maker or equilivant. I like taking crappy old games and repurposing them to see if they will play on an original nes. Looks pretty cool. I take it no zapper function?
