Were there any dos games that did not use HIMEM.SYS, XMS or EMS to provide extended memory but used the old bios Int15 function instead.
Probably limited to late 1980s games to very early 1990s. I'm thinking of games that probably still worked with around 590kb conventional memory but were 'enhanced' when taking advantage of extended memory via int15.

Sierra On-Line games ? Space Quest 3 (re-release version) ? 😀
Command Keen IV supports several memory types, afaik.
There's a message before the game starts.

Thanks for the list, I have only found one game so far, Ultima VII uses Int 15 for extended memory.
