Did some extensive testing with the Multi on the Supergun and Cab.
3 times out of 5. Everything works fine when flashing and playing games. However, I'm still getting the "No Games Found" error every now and then, and almost always on the first boot after not using it for some time.
Also, when booting the cart with new game flashes or even from a cold boot, sometimes it randomly goes to "Initialize File System" again, sits for a short while, and at which point audio in games exhibit huge spikes in volume that cause crackle. If I power cycle, usually the cart boots fine and audio is perfect... Random errors, but any ideas?
