Both of them didn't work on USB Loader GX for me but worked perfectly in uLoader 5.00. Use uLoader.

 

All work for me on wiiflow R25 and above.

Also you might want to update your cios 249 to rev19 and try again.

 

yup all those work on cfg loader 57r5 mload222
i've got all 3 of those games too never had a problem with any of em using the default settings.
but a black screen is probably cause youe trying to play a PAL copy of the game, so i suggest you change your video settings to fix that.
i can't really say why your system crashes though.
oh ya one more thing i have cIOS222[38+37]-v4. cIOS223[38]-v4. cIOS202[38+60]-v4

249 doesn't matter much if your playing off a usb loader

 

Reinstall the games. This happened to me many times and eventually every game on my HDD stopped working. What manager are you using to copy the games? If your using WBFS Manager, then stop. Apparently removing games with that app can cause other games to stop working, and the problem will get worse if you keep on using the app. Tip: Use FAT32. After I lost over 90 games on my HDD, I switched to FAT32, and it works like a dream. No corruption, works fine, and you can use the HDD for other things than just Wii games.

 

All these games worked fine for me with GX 874, using 222 as the main game load, wbfs format - although I now have 921 with fat 32 partition

Are the games in region, if not try patch video - Monopoly is a bad iso as this has only happened to me once and it was the iso at fault

Use Wii Backup manager, do not use intelligent v6 as this does not work for some games.
