Ok so, this is sort of complicated, but here it goes:
I ordered a Breaker Pro like months ago, I guess I didn't pay attention to it not asking me for NTSC or PAL and I live in Europe, that is PAL.
I got an NTSC CD, I put it into the PSX and the CD boots (works) anyway!
I burn some game, I try booting it, doesn't work (yeah, CD spins, just stuck on "Insert game CD and press any button to boot. Booting CD...", so I give it up and try again just a few days ago, this time I again try Google and find out what's wrong, then I see the CDs must be burned with Alcohol 120% on PS mode! Ok, so I get Alcohol 120%, I burn a copy of Kula World (standard PSX game), and holy shit, it works!
It boots, it plays with sound and good colors and everything! So I burn out (or copy) a few more games, and they all work! I play some more Kula, for like an hour, and hey, the colors screws up! I can still play, but it looks basically like the machine is smashed from the screen output, like if you destroy your MP3 player hardware (which I've done), even with a working screen, if you start it up, it'll just show u shit loads of symbols and then sort of bluescreen with some error some seconds later... On PSX, it didn't bluescreen, it continued working, but yeah, ugly graphics and harder to play. So I think I turn it off and play a different game, and I THINK the game didn't work, so now all the CD's doesn't work, only original games (and the Breaker Pro).
I saw something about cleaning the lense? But the original games work 100% full speed, no weird PSX whining sounds, Breaker Pro included....
The CDs are of the brand called Verbatim, CD-R's of 700 (or 699 something or 701) MB and 52x speed.

When burning CDs with Alcohol, I always chose the lowest speed, except once, just to make sure that fastest didn't work any better, and I were right, it worked worse (with faster writing speed), or that's what I recall anyway..
From what I read also, it's supposed to be burned out in BOTH Playstation mode AND DAO/SAO or whatever, that doesn't work, if I put Playstation mode, it automatically change to RAW-DAO or something, and if I change to DAO/SAO, it changes from Playstation to Custom....
So is there anything I can do? I wouldn't know how to clean my lense, and I don't have much tools (I don't even know if I got a correct size screwdriver) -- I basically just wanted to play some PSX games, and I've lost 99% of all my old PSX games (so I was gonna burn out games I used to have, that I haven't sold, but only lost, so it should be legit)

Thanks for all replies.
