Pues eso, que acabo de leer que en la próxima version de ScummVM sale el port para PS2
http://www.scummvm.org/
Esto es lo que dicen:
Ports are important for us -- that much we have in common with the good ol' pirates from Monkey Island. Of course in our case it's not the wet kind (with ships and stuff), but rather ports of ScummVM to different architectures. On that front, we have some pretty nice things coming up for the next ScummVM release, including an official PlayStation 2 port...
Aunque yo personalmente prefiero un port para PSP, que así podrías jugar en cualquier parte.
Saludos.
