I've been slowly working on documenting some stuff about PC-98 game floppies: if they are bootable or not and what DOS they use.

I've noticed there are quite a few "custom DOSes", some which were sold to other devs (SPS MEGDOS) , others that were made by the game devs themselves (Agumix's TDOS).

I wanted to ask about one in particular, a custom DOS used by several games by Active (3ta-kun, Hana Yori Dango, Hana Yori Dango II, if, if 2, Mahjong Gensoukyoku, Mahjong Gensoukyoku 2, Mahjong Gensoukyoku 3, 3ta-kun 2, Sweet Angel).

The file that implements the main DOS is LOADER.SYS, and it doesn't have a name inside it, only a version number.

At the end of the file is the Shift-JIS string "池辺君です !", so I've called it "Ikebe-kun's DOS" in my list.

Does anyone know what the real name of this DOS is?
