Made a new priiloader hack a couple of days ago, not sure if it actually works or not (feedback would be appreciated), but it should block one disc based game from loading. It's in the priiloader hash_hacks.ini format: Code: [Block Disc Loading] maxversion=518 minversion=288 amount=1 hash=0x52414145, 0x00343038 patch=0x524D4350 Should work from 3.2 right up to 4.3. The game blocked in this version of the code is Mario Kart PAL (RMCP). To change the blocked game, change the last line to the HEX title ID of the game you wish to block. (You can use this site to convert the ASCII title ID to HEX: http://www.mikezilla.com/exp0012.html - remove the % from the HEX value and add 0x at the start). Why would you want this? You may wish to prevent one game from being played, perhaps so people don't mess up your progress or whatever. It won't stop a knowledgeable user obviously (they could just disable the hack), but it should stop young children or whatever. Perhaps useful if the game you wish to block isn't a high age rating, so you can't use Parental Controls to prevent it being played. Please post if it works or not, I can't test as I don't use Priiloader. I made this in response to a request at another forum, and figured I'd post it here in case anyone here would find it useful.
