Great. I have the physical cart, is there a way to get it updated with the new ROM?
Yes! There is a post out there saying it's possible using a flash kit since the original cartridge is rewritable!

I confirm that the original cartridge from BitmapSoft can be re-flashed with GBxCart RW v1.4c Pro with the firmware R42+L14 (2025-05-23T10:18:04+01:00) using the software FlashGBX v4.4"
Nice, thanks
