Simply load the desired .pk3 archives with the Wolf3D Macintosh version using latest ECWolf nightly.
Music - DONE
All 8 music files were converted and match perfectly with TFE/TSE/TTE levels.
Download .OGG version
Download .FLAC version
Sounds - WIP
So far only Minigun firing sound has been changed due to ECWolf not supporting all sounds properly just yet.
Bigger weapon sprites - Hard
Super 3-D Noah's Ark has this feature, but Blzut3 made it specifically only for it due to its hacky nature.
Sprite Changes - Impossible
Such as machine gun having orange muzzleflash. No idea how to extract them
Startup videos - Impossible
ECWolf can't play startup videos yet, but it may be added in the future
Then it should be piece of cake.
Menu - Unknown
No idea how menu system will evolve with ECWolf, but I'm going to assume this definitely isn't possible now.
Blzut3 - For making ECWolf and helping me with various stuff
All the devs involved in the cool 3DO port!
