The game freezes and makes an awful sound when I try to save using my GBA emulator on RG35xx.
Hmm, in that case I've probably uploaded the wrong version of the ROM. I had a version that was adapted for saving for specific flash chips, but would crash in other cases that didn't support that chip. I'll see if I can dig up the version that saves to SRAM (which is what emulators usually emulate)
