Do note that just because it runs in accurate emulators (i.e. BGB, SameBoy, Emulicious) that doesn't necessarily guarantee hardware will play nice. During the development of my entry I encountered an issue that didn't pop up in BGB but resulted in graphics corruption in Emulicious + my GBC and a game freeze on my GBA SP. For that reason, I'd recommend testing in all three aforementioned emulators if you don't have access to original hardware and/or a flashcart.
Of course, you're always welcome to ask the folks in the GBDev Discord server for help with hardware testing.
