#1 - plz drop the name calling, I've seen ppl who've been here a lot longer get banned for a lot less
#2 - stay away from pimp my wii. There's a reason why many people refer to it as "brick my wii"
#3 - install the latest recommended cIOSs (i.e. d2x v8 base 56 to slot 249, d2x v8 base 57 to slot 250, etc.)
To accomplish #3, I recommend you use ModMii. You can grab it from the link in my signature. Then you have some choices on how to use ModMii to update your softmods.
a) Run the ModMii wizard and tell it your wii has never been modded before, then follow your custom guide to update ALL your softmods
b) Run ModMii's syscheck updater function. This will analyze a syscheck log csv file (created by your specific wii using syscheck), then ModMii will generate a custom guide for you to update ONLY whatever is deemed to be outdated
c) Run the ModMii Wizard, tell it your wii is already modified, then when asked what you want to update, choose to update recommended cIOSs, then it will build a guide for you to update ONLY your cIOSs
d) Start ModMii classic, from the main menu type "4", then "rec", then "d", then "y". This will just download\build the recommended cIOSs for you in WAD form (no custom guide will be generated), which you can install using your preferred WAD Manager (e.g. MMM)
Then load your game using cIOS249, if that fails, try cIOS223. If it still fails, try re-ripping the game.
edit: just saw you got it working, good stuff. FYI, the cIOS you used to get it working is also ModMii's recommended cIOS223. But if you install ModMii's recommended cIOS249, which uses IOS56 as a base, it should also work for GH5 but it will have the added benefit of faster loading times (relative to 223)
