Hello, My friend asked me to make hima a earthbound pal reproduction! but I cant seem to find the rom anywhere, is there such thing like that?

Hmm, I pretty sure thier is, Try Google.

EarthBound was never released in Europe so there are no english PAL roms.

Also, making reproduction cartridges will probably trigger the anti-piracy setups in the game, so it isn't worth your time.
