hi.u know that new games come with new codes so even if u have the chip it wont work,cause the game has an anti mod chip protection.So first of all,if u'r gonna burn a game,pls check out if its protected on www.gamecopyworld.com the most games aren't protected.
when it comes to CD's use TDK 74 or 80 min CD-R (not CD-RW,it will never work),because TDK CD-R's are as same as the original PSX-game CD's.I should explain it to u why,but my english isnt that good.It has something with laser to do and the depth of the CD-ROM reflection.
All my games work...I have about 30 games,not all are by TDK,but other CD-R work too.
