If you're deep into N64 modding or ROM tinkering, this is one of those niche tools you didn’t know you needed until you hit a wall. The CD64 Bios EEPROM-Burner lets you flash custom EEPROM data—basically, it’s for when you’re knee-deep in ROM hacks or trying to revive some obscure hardware setup.

Version 1.30 cleans up some of the jank from earlier releases, though it’s still very much a "know what you’re doing" kind of tool. No hand-holding here—just a straightforward way to burn BIOS files if you’re working with CD64 hardware or similar setups. Definitely not for casual players, but if you’ve got a drawer full of N64 dev carts, this’ll feel like finding a missing screwdriver.

Just don’t expect pretty menus or tutorials. It does one thing well, and that’s enough.
