Hi! Thx for your interest!
There are a lot of hardware tricks involved in making the GBA port possible, so pretty much anything could happen. :)
Just to clarify: GBA Runner2 is a hypervisor, not real hardware. It translates GBA instructions on the fly to run on the DSi. Things like DMA-driven audio streaming, precise timer usage, and VRAM updates don’t map perfectly through GBAR2, so the game won’t launch or may behave incorrectly.
Unfortunately, I don’t have a DSi to test on, and running GBAR2 through DSi emulation is not a reliable option.
If you’d like to try the builds, you can run them on most desktop and mobile emulators. Real hardware (like an original GBA, GBA SP, or even DS/DS Lite with a flashcart) will always give the most accurate results.
