I have a DMS4 Pro SE modchip and I am able to play legit domestic and import PS1 games on my PS2. The problem is that I cannot play my PS1 backups. I'm using generic CD-R's, so it could be the media. Before I go out and by some verbatims, I just wanted to know if it's the media or is it that the DMS4 Pro SE doesn't do PS1 backups? The backups work perfectly fine on my PSOne, btw.
