Vectrex SDL

Is this portable?

sounds very interesting to me:

vecxsdl is an SDL / OpenGL version of Valavan Manohararajah's vecx Vectrex emulator.

There are several reasons why I wrote vecxsdl:

vecx has the habit of rendering on top of other windows. At least on my system. vecxsdl doesn't. At least not on my system.
vecxsdl supports overlays.
I became tired of vecx's "rom.dat not found" error message, so I linked the Vectrex BIOS into the vecxsdl binary.
Since vecxsdl uses SDL / OpenGL it should also be very easy to port to other systems. I only provide win32 binaries, though.

Ian has released a M.E.S.S. Vectrex emulator. I think its full speed.

Might be. If it uses OpenGL line drawing then it probably won't work on a Dreamcast yet (because KGL only does polygons, not lines). Most modern 3D cards implement line drawing as polygons anyway, so that could probably be added fairly easily. Might not look too good unless we can enable anti-aliasing though.

Mess one is only about 60% speed with sound but includes all games. Rather hard to get fullspeed. Found KGL to crash and be unstable on some things running out of memory is one. If it's SDL/ with open gl on top that crashes more times then it runs or just has a black screen.
