I started trying it to work and so far no success.
I put in the SSBB code: Disable Time Limit On VC Games, but it's not working. Do I have to use that code alone then apply the others or do I have to do it with every other code for the games? When I go to a VC game on SSBB the screen goes black and just hangs there.

Also: Can Gecko OS be used for GC games through the HBC?
You must first use the "rebooter" (as stated) through the HBC. Simply press "B" on the wiimote and you'll be taken back to the menu from which you load SSBB.
Note however that when you start a game with this code it get's treated as a stand-alone chanel and leaves the game (SSBB) entirely. You cannot get back into Brawl after starting. The game just freezes (out of own experience).
To the second question, Yes you can load GC games with region free options through GeckoOS, however they've not yet implemented the GC "hook" (i.e. no codes).
How do you get rebooter options on the menu for gecko os 1.9.3? There isn't even an option to reboot.....
