I noticed that what you wanted was actually something else, but I'm anyway answering these...

Atari demos in general don't support/require long filenames (or other MiNT GEMDOS extensions). As to emulators, e.g. Hatari presents long file names in 8+3 format accepted by normal single-TOS compatible Atari programs.

Inside one of the Atari emulators. In Steem you need 68000 build of MiNT (rare), in Hatari you can use normal 030 version (e.g. under TT emulation). You need to use hard disk image for that though. With Aranym, there's Atari MiNT driver which interfaces so with the emulator that long file names on the host computer are also visible inside the emulation (as MiNT replaces TOS GEMDOS part with its own version that supports long file names).
