All games in this release use the same save slots. So if you play for example Doom 2 for completion and then change to Doom 1, using the saving there will overwrite the saves in Doom 2. Nothing wrong with that, if only one had known earlier...

If anyone has problems with cursor moving to the edge of the screen, try disconnect any usb devices such as joysticks or printers, NOT keyboard and mouse ^^ Change the resolution to your liking.
