Just tried it, it's a seriously slick port!
Runs very smoothly on my A1200 with Vampire V2 V1200 in RTG mode. I used the 060 version.
Do you plan to add the ability to select an RTG screenmode?
-EDIT- Something I just noticed when playing it again, this time with a controller. I have to unplug the controller when in the game menus otherwise it randomly moves the selection and selects things. In game, it works fine.
