Go back to basics.
Get your emunand setup, copy loader.dol to usb:\apps\triiforce folder and rename it to boot.dol
Run boot.dol from HBC and make sure that your installed tiles are loading when run directly. If you can't get them to run direct you will not be able to run them with a forwarder.
If they crash, try again with different options set (usually video)
If you cannot get them running this way then your wadfile is corrupt or maybe the nand is not setup correctly.
Once you do get them running directly they will run via ISO forwarder with the same settings applied in Wad2ISO's options screen
:// EDIT
Just a thought - You do know that your EmuNand must be setup in the ROOT of USB: or SD: right?
(Some later apps allow it setup in a folder but this is NOT compatible with Triiforce)
Yep, I know all this. The issue is something to do with emunand I think. I'm pretty sure I can get it to read no problem if I'm on a later cios, but then the issue lies in needing r17 to do n64 vc games. The forwarders are working no problem, cause I was able to get them to work on the rare occasion my emunand was read (only when I dumped it with usbloader GX and made absolutely no modifications to it before going into triiforce). Triiforce just doesn't like me for some reason, it crashes before I even get to select a game when it tries reading the emunand in most cases. I might just get the glitchy emunand that usb loader creates back, then use it to make forwarders for Mario Party 2 and Smash Bros (the only working games it seems to produce) then install the rest I plan on using to the wii menu. I should get most of them on that way I hope, I just can't figure out why Triiforce only works with that one way of dumping my nand. Bootmii, fresh nands, the one I use normally for USB Loader GX all crash it, I've gotten to the point where I just can't understand why it won't work or where to try tampering with it. But anyway, it's not a major loss for me and I can live without being able to access a few games at a time.
Thanks again for all of your help and such.
