Brigandine lags alot! Can't figure it out...

[octopus]

Whenever I try to run Brigandine (one of my favorites from the PS), it becomes extremely choppy during most of the game, as if it were pausing on and off, though that isn't actually the case (it doesn't say PAUSE as it would).

I tried searching the forum, but could not find a solution.
The game is running from a CD in the CD drive.
I tried several other games, and they all work perfectly. Only Brigandine messes up.
There is another window in the background that loops the message over and over:

IoControl: retrying <#>
IoControl: raw read error, Incorrect function.

The # starts at 1 and counts up every time the message appears until 16 and starts over.
At certain screens (loading before the title, and on a few menu screens) it does not do this.
One time, I was able to play for a while without the problem, but I foolishly closed the game, and the problem persisted the next time.
The CD is slightly scratched, but it works perfectly fine on my play station.

Well, I think that's all there is. I hope you can help me, and that the information provided can make it easier for you to figure out the problem.

Thank you.

Despite it working fine in your PS1, it sounds like a disc reading error (especially from the console error you gave). This doesn't necessarily mean you have a bad disc. It's certainly possible that maybe your drive isn't the greatest with reading PS1 discs (to the point that even those few scratches managed to affect it). Also keep in mind that a PS1 tends to read PS1 game discs better than many computer drives.

You could *try* using the ASPI layer reading method instead (which involves installing ASPI if you haven't already), though that probably won't make a difference. Best advice to give would be to either try repairing the disc to see if that helps, or extracting it to an image file. Use something like Alcohol 52%/120% with the "PlayStation" setting and Enhanced Weak Sector Scanner on, at a low speed like 4x or 8x, to ensure as clean an image as possible.
