I have a silver account with the SNES emulator achievements on. Was wondering since xbx.com doesn't see them could I remove them some how via GPD. Any ideas or help would be great.
Yup bud, you can remove them as long as it hasn't been signed into live yet. I'd use exPE (ex profile editor) to remove the game from your list.
You should be able to remove them as long as you haven't signed into LIVE since the first time you played it.
Here you go http://www.mediafire.com/download/zyfleqv8zmn6g46/2.06.rar Should be pretty easy to figure out. Open the profile in Horizon and extract all the contents into a folder. Open that folder in exPE and change what you want. It will create a new folder called "Changed Files" or something along the lines...just replace what GPD files it changes in Horizon.
