Ok so i fanlly got monster hunter tri to work a few days ago, and so far working stable and fine and no more freezing and beeps after choosing begin game. Tried all the crap about the hermes 222 installer but nothing worked there. Finally found something out of the blue on the net which actually did work. I used a newer version of the installer than the thread mentionned, but still solution was there. U need to download waninkoko's custom iosx installer rev 20 or 21 and then choose to install ios 249 (default one when u start the installer) then choose IOS 37 rev whatever and after that choose IOS 249 again then network install. I used rev 20 of waninkoko's installer so might be a bit different on the one you will use, but the IOS 37 is the charm here anywayz. Then went in settings for monster hunter tri in the GX loader and put game IOS to 223 and bingo bango it works and plays great!! And i'm also running this on version 4.3U so i can confirm everything is fine even with latest update of the Wii. Hope this will do the trick for you guys, cause i sure know i had a hard time and got frustrated trying to get this great game to play.
