EOB 1 & 2 has been converted to AGA by CFou! (great job!!) so I guess the asm code is a bit better than raw output.
I've got a reassemblable version of Battlechess (not really resourced, though) where I had hacked to replace trackloading by diskimage loading (to create a HD version)
BTW Cinemaware confess having lost all sources of their games
Near 1996 some editor wanted me to do a HD version of a football management game, and he sent me the asm source. I could not do anything with it (I don't remember the name of the game either!) so I either deleted it or it's lost in my backup CDs (knowing the name would help
I remember it was 68k assembler but the production machine was already a PC so I was having a hard time rebuilding it with phxass!!
