Currently undergoing changes for maps with BOOM support. Countless code lines have been adopted from DOOMretro to achieve this goal. Still fighting with a few bugs, but currently looking good so far. For a test, VALIANT.WAD and MONSTER HUNTER 2 (MOHU2.WAD) do work. The rendering engine as well as DEHACKED engine have been completely adopted from DOOMretro with a few slight changes by me for this port.
