Got the multi few weeks back:
Ran it on both MV-1C and MV-1FZ stock bios for both.
Haven't played a lot of games, all games played ran without any issues.
Windjammers
Baseball Stars 2
Pulstar
Updating the firmware follow the instructions properly - easy. Loading on 8GB TDK Class 4 SD Card ran without issues.
I have put it away for special occasions though so wont be testing a lot.
Overall another quality product from DS.
