Would probably be enough to get games that don't directly access ST registers to work.
I suspect just like Amiga, you can call a certain TRAP to get a base address for a screen, and call a TRAP to activate that base address to setup screen and display.
I'm afraid it could be a little bit more complicated than this. Games not only setup the screen but also use a lot of other features. For example OIDS even used the TRAP #2 for some graphic operations.
