Hello

I succeed to use SIGIL with original ultimate DOOM DOS on real old hardware with soundblaster AND MIDI out music.<
Thanks to ShadowHog, I found a modified version of the original DOOM.EXE that changes several game limits :
limit : old * k = new
-------------------------------------------------------
visplanes[MAXVISPLANES] : 128 * 8 = 1024
drawsegs[MAXDRAWSEGS] : 256 * 8 = 2048
SAVEGAMESIZE : 180224 * 16 = 2883584
activeplats[MAXPLATS] : 30 * 256 = 7680
vissprites[MAXVISSPRITE] : 128 * 8 = 1024
linespeciallist[MAXLINEANIMS] : 64 * 256 = 16384
openings[MAXOPENINGS] : 16384* 4 = 65536
-------------------------------------------------------

Now, Sigil is playable with vanilla DOOM
https://sourceforge.net/projects/prboom ... us/1.92.2/


An other developper has modified this Doom+ exe to improve SIGIL compatibiliy :

Thanks for posting this! Wanted to try out Doom Plus after leileilol findings, but this is even easier. Running this with a SB16 fox FX and a GUS for music is really great. I do seem some drops in framerate in the more complex scenes, but no issues otherwise.
