Hopefully this will clear up any doubts on the issue. I've seen multiple people ask if changing the IOS to something other than the System Menu one (see Priiloader's settings if you don't know what I mean) would let Priiloader run in the event of your System Menu IOS being stubbed/deleted. I have not known either way, but I didn't bother trying it until tonight. It's a very dangerous thing to test, so don't do so yourself. I backed up one of my boot2 Wii's that was running 4.2, then changed Priiloader to use IOS60 (which isn't stubbed). I installed a stub IOS70, then restarted to get a black screen. That was to be expected. I turned off my Wii, then back on while holding RESET button. I held RESET for over 10 seconds. I got a black screen! Priiloader would not load! I restored my nand with bootmii and everything is running smoothly. Again, I don't advise that anyone test this themselves. The whole reason I did this was to prevent anyone from thinking Priiloader could save them from such an event. --------------------------------------------------- Test Results (will be updated after each test). Stats before for changes: 4.2U on DarkCorp v1.1 IOS70 Priiloader v0.5 using System Menu IOS. Test 1: 4.2U with stubbed IOS70 Priiloader v0.5 using DarkCorp v1.1 IOS60 Result: Black Screen, can't access Priiloader or System Menu Test 2: 4.2U on DarkCorp v1.1 IOS70 Priiloader v0.5 using stubbed/deleted IOS60 Result: Priiloader appears upon boot giving the following error: When I went to Preloader to change the IOS back to 60, the current IOS was set to "1195917891". Either changing it back to IOS60 or re-installing IOS70 will fix it. Test 7 4.1U with stubbed IOS60 Preloader v0.29 using DarkCorp v1.1 IOS70 Result: Black Screen, can't access Preloader or System Menu Test 8 4.1U with no IOS (deleted IOS60) Preloader v0.29 using DarkCorp v1.1 IOS70 Result: Black Screen, can't access Preloader or System Menu Test 9 4.2U on DarkCorp v1.1 IOS70 Preloader v0.29 using stubbed/deleted IOS70 Launching System Menu through Gecko OS rebooter. Result: System Menu loads properly on IOS60. Preloader is skipped and hacks are not applied.
