Green debug playing only audio cd

Post by **Ichisuke** » June 19th, 2020, 4:17 am

Hi everyone, I'm new here but sometimes I read this forum because it's very fascinating. I decide to register since I have a problem. So, I have this jade green PAL debug (late PU-8 board) from quite some time. From when I bought it was playing games correctly. Then after leaving it in the closet for about 3 months untouched it just refused to boot up the games (original won't just load). Audio cd are recognized correctly and play just fine. The console starts to read the game disc but it seems to refuse to "change" speed, it just stops and starts again at reading the disc infinitely, it doesn't reach the playstation region logo. I've tried two correctly working PSone laser unit, no change....
Hope someone can give me some hints.

Thank you.

The board itself might need to be calibrated because the older PU-7/PU-8 boards didn't do automatic calibration. Only the later board revisions did that.
