Hi
I have released MGRX, it stands for mini-grx or my-grx or Mariano's grx. It's a fork of GRX, only C API, no BGI, no add-ons, only 4 platforms supported: djgpp, mingw, linux-framebuffer and linux-X11. A new and different input API. And support for x86-64.
The main site is http://mgrx.fgrim.com
Greetings, M.Alvarez
