Place all .ps2 dongle files into the "memcards" folder and the System 246 and 256 BIOS files into the "bios" folder.
Once you have the "roms," "memcards," and "bios" folders fully set up at the root of your emulator directory,
delete all other emulator files and folders (keeping only roms, bios, and memcards). Replace them with a fresh,
clean download of pcsx2x6. Then, launch pcsx2x6, go to "gamelist," and open each game folder one by one—do not run a full scan,
as that will mess things up; you need to process each game folder individually.
Next, go to the exclusions section and do the same for each game folder one by one to exclude the boot.elf and proverb.elf files.
You will then have a nice game list in pcsx2x6, and all you'll have to do is click on a game to play.
