Cave Story had many ports (Linux, Mac, PSP) but none for DOS? That's just blasphemy.

What could be done in a port:
- Allowing 320x240x8 by color remapping to an optimally generated palette. The hard part is giving Doctor its own palette to calculate a red fade in. This would be faster than running in the game's native resolution of 640x480x16 (2x pixel scale, with sharp fonts)
- Using a fixed pixel font instead of interfacing with truetype or freetype
- Option of OPL-3 Org? The music code stands between running the game on 486 class machines... or at least a lower sampling rate option.

As of now, the game doesn't function under Windows 95 or even HXDOS. It relies on some Windows 98 shell dependency for a no good reason (it doesn't even touch "My Documents")

No, I can't port it - wish I knew how.
