I wish i knew how to code so i could just make something (in this case, a sega forever file decryptor) when i wanted it

Knowing how to code alone wouldnt help you much with hacking encryption / decryption. They are two very different disciplines.
 
The legal debate here is actually more nuanced than people are making it out to be. Extracting assets from software you legitimately own for personal use sits in a gray area that courts have not fully settled in most jurisdictions, and the DMCA argument gets complicated when the original software is a free app.


The technical side is interesting though. Sega Forever titles using encrypted ROM packaging at runtime is a deliberate choice, and it explains why standard APK unpacking tools come up empty. The encryption happens in memory during execution which is why you would not find a clean ROM file sitting in the directory structure.


The hex editor approach mentioned earlier is probably the most reliable starting point. If the ROM data is embedded rather than downloaded separately, there should be recognizable header strings somewhere in the binary even if the surrounding data is obfuscated. Tools like binwalk can also help identify compressed or encrypted sections within the APK that might not be obvious from a standard file listing.


Has anyone here actually gone through the full process of analyzing a Sega Forever APK in a memory dump during runtime to see what gets loaded into RAM when the game launches?
