Really awesome concept but if the game is saving every second you should warn folks not to play it on carts such as the EZ Flash Omega that try to save directly to the SD card - for those carts, you are meant to wait a number of seconds after saving before powering off the system, otherwise the SD card will be corrupted. If the game is constantly saving there won't be a safe point to turn the system off.
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.
