One of the coolest features of the Polymega is that it allows you to patch games on the fly. All you need to do is use some form of external memory, an SD card, a USB stick, etc. create a folder called Patches and dump your patches in there. That's it, that's all. Once on the Polymega's dashboard you select your game, select the patch you want installed, wait, and enjoy. The system is also compatible with pre-patched games as well, and I show you how you can check the database to see if your game is compatible or not. Naturally certain versions of games will be compatible while others won't be. Patch formats Polymega accepts include: IPS, PPF, UPS, BPS, XDELTA, XDT, and XD.
