I recently got myself a Wii...dont know if it is modded or not...but it can run back up games via Homebrew Channel and SoftChipR83m Loader...so heres few questions I can think off.... 1. how do i check my Wii Firmware? If I update its firmware, will it affect the channel? (like the PSP where homebrews cant be used if i should try n update it?) 2. can I play wifi games even though I'm using a back up game? Will my Wii get locked or something? 3. is it safe for me to use the channels such as forecast channel/news channel etc? I'm afraid it'll affect my Wii (same as no.2) 4. what sd card does it use? 5. are there any cheats which i can use with Wii (something like gameshark or action replay?) if yes, how do i install it? thats all questions I can think of at the moment.... forgive me for my bad english... and thanks in advance for your time.
