Same here cause i have 1.2 and 1.4 and 1.4 doesnt have the disable cdrom status so i switched to 1.2 and enabled disable dc rom status, Well theres prolly a way for it to work on 1.4 but i I Dont Know and im still figuring it our if anyone can knows plz tell us.
Here is my CDROM config for GT1 ( I just have it right in front of me because I play GT1 at work during lunch time )
UNCHECK Enable accurate cdrom timing
UNCHECK Disable cdrom status
Now when you say GT! doesn,t work is it a complete black screen right from the beginning ? ( I mean youcan't see nothing at all ) in that case could be the video plugin config, or can you at least see the intro message displayed on the screen ( in that case it looks like a cdrom config. problem )
I hope this helps
