Hello. I saw that it's impossible to save J2ME game progress into a file. There's no disk I/O stuff. However, on a J2ME app called VibeJive, I saw that there's an RMS exporter programmed in a single class file that allows the user to save the app data (called RMS) so that they don't lose it while moving from one phone to another or while doing a master reset of the phone. It's a backup option for short. The MANIFEST.MF file contains data about whether the user wants to launch VibeJive or RMS exporter. Someone uploaded that solution so that J2ME gamers can backup their game progress.
I'm thinking about opening up my game's jar file, editing the MANIFEST-MF file and adding the RMS exporter class file into the jar file. The EULA says that I may not reverse engineer my games and I don't know if this would count as reverse engineering since I'm not touching any of the other class files that are contained in the jar file. This is why I'm asking for permission to do this. What do you think, Clickteam?
