This a port of DOOM to the MicroBlaze architecture.
A Sconscript file is provided to compile the source code into a little-endian MicroBlaze elf file.
$ cd linuxdoom-1.10
$ scons
To run it you'll need to compile the MicroBlaze emulator (https://github.com/finalpatch/mbemu) from source:
dub build --config=doom --build=release
