Put game1.iso (or whatever you want to name it, Devolution is intelligent enough to scan the .iso and know its disc 2) in /games -not /game and it will load them fine (may have to hit eject on your console when its trying to load disc 2 (or asks to load disc 2.) If the loader (Wiiflow) doesn't define where the .iso are located, Devolution defaults to /games ..
I just set mine up this way /games has all my games with subfolders i.e, usb1:/games/Killer 7 [GK7E08] contains killer 7 disc 1 labeled game.iso , disc two is labeled usb1:/games/killer7-disc2.iso and this loads them fine. I do however have to hit eject to go from disc 1 to disc 2, I'm hoping if tueidj adds Wii controller support or possible keyboard support he will have a shortcut / key map to the eject call also.
Just tested 2 disc game with both games named game.iso and gam1.iso located in sub dir like this usb1:/games/Killer7 and runs fine with Wiiflow (when I have an sd card inserted that is ) as I can't run devo through wiiflow w/o SD card in machine. Devolution will still default out and look to /games if it isn't found within sub dir.
I haven't gotten to the part where I need to switch but, when I do get to the end, when exactly do i hit eject?
