Gameboy Battery Test

This project was inspired by https://santiagocrespo.itch.io/gb-battery-test

Their battery test is a great tool, but it has one issue for my particular use. I wanted to load it onto an MBCX cartridge with multiple games on it, but the way it works resets the RTC registers on each start, causing other games on the cartridge to lose their stored RTC values.

I tried to modify their project, however the way GBStudio works is a bit at odds with the way I think. I decided instead to write my own version using GBDK-2020 in the C language.

The included song is a sample project from hUGETracker called "Jester - FishNChips.uge"

I am using the hUGEDriver library for the music.

the source for this application is on github (will open this soon*)

requires a MBC3 + RTC cartridge or compatible flashcard

I hope you enjoy
