dimok321 928020b32f *Added AlternateDOL from disc feature 
*Added Browser for AlternateDOL from disc feature

NOTE: Right now the browser isn't working right and crashing from time to time so you i would not recommend to use it yet. It's also showing all files on the disc for test purpose. I'll try to fix it later right now i don't have time for it.

*Changed some minor codes and moved cheats to its own folder
