I have a soft modded Wii 4.2E, D3-2 drive and latest USB Loader GX.

Every time when i play game for about 30 mins the game will freeze up and i have to reset the Wii. Do you know why?

I load the game from USB thumb drive not HDD. I have cIOS 222/223/249/250 installed and i try to switch it around but the problem still occured.

Please help me fix this.
Thank you very much
