DMS3 install problem in PS2 v4
After installation of a DMS3 v2 in a v4 PS2, all disks (orig and backup PS1 and PS2) fail authentication. Disks spin and are read but each time I get the "red" screen saying that the disk is invalid.
Also, when I disable DMS3 by booting with the open tray button, I have the same issue: all disks still don't authenticate.
BUT: Using a mem card (which was installed on another console) with DMS explorer and PS2 Reality Mediaplayer, I can go into DEV mode en start PS2RM.
All suggestions to solve this are highly appreciated.
