Homebrew Looking for a simple GBA ROM that shows the time or works as a stopwatch

[Charli]

I'd just like to somehow show the time progressing on my GBA Ideally with seconds or even milliseconds

I've found reddit posts of others looking for sth similar but there doesn't seem to be any Homebrew game that can do this?

I've found this for the DS though: https://www.gamebrew.org/wiki/Stopwatch_DS

I don't know of a good stopwatch app, though I don't suppose it would be too difficult to program one.

As for showing the time, unfortunately the GBA does not have a built-in Real Time Clock like the DS does. Some older GBA flash carts had batteries specifically to play Pokemon games properly, and there are a couple programs out there that may help set or reset the internal clocks on those cartridges, but unless you have an X-ROM or a Flash2Advance Ultra I don't think any of my archived tools will help.

Modern flashcarts like the EZ Flash Omega do, too.

Ah, I wasn't aware of that. Thank you for the correction. I'll go ahead and attach the one tool I can easily find. I wrapped it up in Multiboot Menu for some reason.
