what's the best sony cdq-74cp or tdf media?
 

for copying all types of games?

I suspect you're talking about Sony CDQ-74CN and TDK CD-R74 media. They're all very high quality.

Sony CDQ-74CNs have been known to be made by:
- Taiyo Yuden Co. Ltd.
- Sony Corp.
- Mitsui Toatsu Chemicals Inc.
- Mitsubishi Chemical Corp.
- Ricoh Co. Ltd.
These are all high quality manufacturers.

TDK CD-R74's are made by either TDK Corp., a high quality manufacturer, or Ritek Corp., a medium-high quality manufacturer. Ritek have improved the stability of their media over the last year or two so now they're producing high quality media :-)
