Hello all! First post here.

I'm trying to port the original doom source to a mips device with no X11 server let alone SDL (and no svga either but i guess that would be easier to install). As far as i searched i found that there were a svga port (i found the linxsdoom executable) of the original code but i can not find it's source anywhere. Can any one help me please?

It's all too easy to find. All you needed to do was search for the original source code release of Doom since they never released the DOS version because of issues regarding the sound library. But here's the github page for the official release of the linuxdoom code.

Indeed this is very easy to find but i'm searching for a version which does not use the X11 library but svga (or at least includes an svga driver as an alternative)

I think it would be easier to use a SDL Doom port as a base. SDL as been ported to many devices and its API is very straightforward if you want to rip it out and replace it with you own.
