Насколько я понимаю в 4-м апдейте к 3.71 М33 есть такая фишка для игр сконвертированных с помощью Popstation_md.

This popstation is for create multidisc games only.
To create single disc games, continue using old popstation.

- How can I change the disc?
The disc change option is usually in grey until the game asks you to change it.
Sometimes the option may be in white even if the game doesn't ask a disc change.
Do not change disc if game doesn't ask for it!
If you want to force a change of disc, use the "Restart game" option. It will ask you with which disc
to reboot. Pops will remember last disc in which you booted.
