Making an Earthbound famicom repro, EPROM suggestions?

[jpx72]

It's because UV EPROMs don't have legs like RESET or WriteEnable or ReadProtect that need to be connected somewhere... on UV Eprom you don't have to solve it when VPP is unconnected and that kind of shit. There are so many FLASH chips with different logical tables you need to look at... for UV Eproms, all you have to do is check the already made http://nesdev.parodius.com/NES%20EPROM%20Conversions.txt
UV Eproms have pretty much all the same pinout.

I am going to do this on a donor board. I've never ventured into making reproductions, but what kind of mapper does this game use and what would I do to get an eeprom to work in the cart since I assume the layout of the eeprom is different than the original roms? Sorry if this common knowledge, but I am new to the whole repro scene.
