Sonic 4 Episode II has never worked on iOS 7. It instantly crashes each time. As it has been almost a year, it does not appear that Sega will fix this (which is very immature as they have left it up for sale this whole time). The thing is, the Lite version of the app works fine. I feel like there could be a jailbreak fix to make this work, perhaps a permissions problem? Or maybe we could switch the files in the Lite version for the Full one. If anyone is interested in this project, let me know.
