Hi Erik, thank you for replying. That will be amazing!
I used Windows 7 with Calamity's CRT Emudriver installed, which is a hack of ATI/AMD drivers allowing 15khz support. His accompanying tool, VMMaker makes it easy to add custom resolutions.
With the desktop resolution set to 224p Rising Up in full screen is pixel perfect, which was great to see as sometimes auto-scaling ruins modern pixel art games. It's a bit cramped navigating Windows at such low screen resolution but it's just about possible.
