UnZip will list, test, or extract files from a ZIP archive, commonly found on DOS and Windows systems. A companion program, Zip, creates ZIP archives; both are part of the Info-ZIP project. Both programs are compatible with archives created by PKWARE's PKZIP or Nico Mak's WinZip, but in many cases the program options or default behaviors differ.
Vim is an almost fully-compatible version of the Unix editor Vi. Many new features have been added including multi-level undo, syntax highlighting, commandline history, online help, filename completion, and block operations. It is descended from the vi clone "stevie" and runs on many systems, including Unix, MS Windows, OS/2, Macintosh, VMS, and Amiga.
Zip is a compression and file packaging utility for Unix, VMS, DOS, OS/2, Windows 9x/NT, Amiga, Atari, Macintosh, BeOS, SMS/QDOS, MVS, VM/CMS, and others. It is analogous to a combination of the Unix commands tar(1) and compress(1) and is compatible with PKWARE's PKZIP and Nico Mak's WinZip. It's part of the Info-ZIP project.
gnuboy emulates the Color GameBoy handheld console in portable C, with interfaces for X11, Linux fbcon and svgalib, SDL, DOS, and Windows, with other ports planned in the future. Compatibility with ROMs tested is around 99 percent, and all major hardware features except SGB extensions are supported. With the optional optimized i386 assembly code, gnuboy can run at the full 60 FPS even on Pentium/75s and below. No special libraries are required to compile, and gnuboy is known to build on many *nix variants.
