hehe BIAS and GAIN control the … voltage? well… power anyway of the lazer and the speed at which the spindle rotates i think.
It’s what we used to use on stubborn PSX’s to get them to work with copied games.
I wouldn’t recommend playing with it if you don’t know what the small potentometers look like… they look like little screws on little boxes and they should be labelled but once again if don’t have a clue what you’re doing then don’t adjust the BIAS or GAIN… it can damage your lazer unit.
Righty, the other option is to use another media type. Try Princo - these are usually compatible media and will work with many stubborn drives that will otherwise say “no” to CD-R media.
Ohh and i can hardly forget the old PSX favourite of burn at the lowest possible speed. However, many burners nowadays produce bad burns at low speed due to their firmware. I suggest you use the same media and try at different burn speeds, and see if you get any different result.
