"vi is hard on the brain, but Emacs is hard on the hands." (Of course, you can always rebind Emacs to something else. Besides, what other editor can play gomoku? :-D )

You can (like I did) compile GNU Emacs 22.3 from srcs for DJGPP. Since 22.1, the buffer limit is 256 MB now (although modern Windows, esp. Vista, greatly hinder it by reporting bogus DPMI memory amount values). However, I've been told by a certain Emacs Lover Infinitum that 23.0.60 (in CVS) is the only active branch, so maybe waiting for that is best (unless you need UTF-8 support, like, now, which 20.5 doesn't have. 23.x will have internal UTF-8 and is already considered plenty stable by some.)

The only tiny bug (bogus warning, really) is in startup and is fixed below (in case anybody cares to compile it themselves: 39 MB .tar.gz srcs, unpacks to 150 MB on NTFS or worse on FAT, just do "config.bat msdos" then "make install"):
