Some things can be found in the first post - but can well, be seen as a little bit unclear... thus I asked - and got answers

thanks for that
Good to know the /codes/ folder is universal. And I figured as much w the disc games but wanted to be sure.
And as for cheats - you only have 1 file that you can edit and add to per game? But What if I'd have have two diff cheat files in /codes/ and in actual game's folder? would it read both? or just prioritize the one in /codes/?
I will wait for a reply on the Wads question - and post it in the other thread too.
Thanks sooo much for helping out a n00b.
