You'll need to be registered at to be able to download these games. I also believe I got those Wads from a different place than all the other Wads I've been using, but that wouldn't make a difference would it? I tried selecting IOS249 and IOS80 in YAWMM as you said, and as it's been a while since I tried all this I also tried again using WiiMod Lite, and for both Wad managers I tried using an original Wad (NTSC) and converting it to PAL with both FreeTheWads and ShowMiiWads, but I had no luck again with any of these combinations: I might also add though that a month or so ago I managed to get a few PAL-converted N64 Wads working, but I can't remember how I got them to work, and they were playing at the wrong speed anyway. I've been selecting 'no' but should I be choosing IOS 249 instead? My system menu is 4.3.
I might also add - when I start up YAWMM it says HW_AHBPROT is disabled and asks if I want to load another IOS instead. I only tried installing 2 Wads with Wii Mod Lite though, because after when I tried to go back to the main menu of Wii Mod everything would freeze, which I assume is not meant to happen, So I tried installing 3 other Wads with YAWMM again but as I said, no luck.
