Comment (by compn):

 there is an open source sega cg emulator
 https://emulation-evolved.net/
 with source http://mk2k.net/releases/pc/emu/gensplusrewind-1.1-src-
 mk2k.zip

 so at least , if the segacd format isnt already reverse engineered
 https://wiki.multimedia.cx/index.php/Sega_CD
 some sega cd video formats have been looked at:
 https://wiki.multimedia.cx/index.php/LMS and
 https://wiki.multimedia.cx/index.php/Amazing_Spider-Man_BIN well probably
 more https://wiki.multimedia.cx/index.php/Category:Game_Formats

 we can use that emulator source to reverse engineer it. possibly.

 if you know of other emulator source code we can look at, it makes things
 easier for us.
