Wow, what a truly amazing effort! Plays great and works also with my Turbomaster accelerator for a slight speed increase (well almost, the left strafe key doesn't seem to work when accelerated, go figure!). 1351 mouse support works great as well. Any plans to include a load & save game option?
I'm not sure there is any option to emulate the Turbomaster, unfortunately it's not very common but probably a perfect Mhz to play games like this.
A level-skip, or select a level from the menu, would also be an option for those of us that rarely get the time for a play through in one sitting. Particularly if you ever consider adding all the episodes :)
