Hi, thanks for the kind words, and for the warning!
I only have an Everdrive GB (1st model) at home, and it doesn't have any issue with this as it saves the SRAM content on SD cart only when we are loading a new rom. But if you have a Flashcart that writes directly the SRAM contents on the SD card, yes, it definitively can be an issue I guess.
The current version of the game doesn't have a pause feature, but I'll add it for a next version so people with such a FlashCart can "disable" the SRAM writes to avoid corrupting the SD card.
Regarding the EZ Flash Omega, can it run GB/GBC roms? (as it's a GBA flashcart if I'm not mistaken). If no, I don't think this device will be able to run the game: to run this game on a GBA you should run it from a "Game Boy" Flashcart so the console switches to the "GBC" mode instead of the GBA one.
