I've run into something strange with Rebel Strike and I need other people to confirm whether this is an issue with Devolution or an issue with my official Nintendo 251 block memory cards...
With my memory card plugged in, if I turn on my Wii from a cold boot and do nothing else other than load up Devolution and Rebel Strike, the game will say that my memory card is damaged and cannot be used, and selecting "Retry" doesn't help. This does NOT happen if I were to actually launch the game from the disc or if you use an emulated memory card (even if it's a dump of the same exact physical memory card).
However, if I view my GC memory card save data via the Wii Menu's save data settings and THEN load Devolution and Rebel Strike, my memory card will be read perfectly fine.
This happens with both of my official Nintendo 251 block memory cards.
