i've created a Lua Flasher ... Your thinking "AHHHHHHHHHHH another one" But the thing is this one lets you flash numerous files and you dont have to put them in your root of you memory stick.
It also give you the option to backup your files anytime you want and wont create a backup evertime you run it, thus overwriting your old one and totally ruining the purpose of having the backup's in the first place
If you find anything wrong with it let me know through a PM or contact me at email@example.com
