Aleph One is a 3D first-person shooter game based on the game Marathon 2 by Bungie Software. It is set in a Sci-Fi universe dominated by deviant computer AIs and features a well thought-out plot. Aleph One was originally a MacOS game, but a cross-platform version ("Aleph One/SDL") based on the Simple DirectMedia Layer (SDL) library is currently under development which runs under Unix, BeOS, and Windows.
cxmon is an interactive command-driven file manipulation tool inspired by the "Amiga Monitor" by Timo Rossi. It has commands and features similar to a machine code monitor/debugger, but it lacks any functions for running/tracing code. There are, however, built-in PowerPC, 680x0, 80x86, 6502 and Z80 disassemblers and special support for disassembling MacOS code. cxmon is primarily intended for emulation development but it can be used as a generic tool for manipulating and analyzing binary data and machine code, or just as a hex calculator.
Frodo is a free, portable C64 emulator. It focuses on the exact reproduction of graphical effects possible on the C64, and comes in three "flavors" (Frodo, Frodo PC, and Frodo SC) with increasingly higher quality of emulation, but at the cost of higher processing power requirements. Frodo has been ported to a number of systems, including handheld computers. The Unix version can use either SDL, X11, or SVGAlib to display the graphics.
SIDPlayer is a replayer program for C64 music (SID tunes), running under BeOS and Unix. You can think of it as being a stripped-down C64 emulator that only emulates the CPU and the sound chip of the C64. SIDPlayer can be used as a stand-alone player or, under BeOS, as a plug-in for CL-Amp and SoundPlay.
The aim of xloops is to calculate 1PI Feynman diagrams with one or two closed loops for arbitrary processes in the Standard Model of particles and related theories. Results can be returned both algebraically and numerically. All necessary tensor integrals are treated for arbitrary masses and momenta. xloops-GiNaC is a partial re-implementation of the original xloops program based on the GiNaC C++ library for symbolic computation. It currently supports calculating one-loop 1-, 2-, and 3-point integrals to any tensor rank.
