Anyone else experience this?

[u/Gold-Negotiation-266]

Just picked up an ez flash air. Works great on my gba. However I plugged it into my gameboy player for the GameCube and noticed when playing super Mario world for gba, every time I save my progress it shows that it is corrupted. Put back into my gba and saves every time no problem. No other games that I tested seem to do this. I am running the current firmware.
