Free gem software for linux

Gem Drop X is a fast-paced puzzle game where its your job to clear the screen of gems before they squash you! (Youre at the bottom, theyre at the top, and they keep coming!)
Gem Drop X was directly ported from the original GemDrop for the Atari 8-bit, which was based on "Magical Drop III" by SNK.
You grab gems (up to 10) of the same color and use them to knock more gems off the screen. Match 3 or more of the same color in a column and >BAM!< they explode! Any adjacent gems of the same color also explode, causing a chain reaction that might cover the entire screen!
The more gems that disappear with one shot, the higher the score you get!
Main features:
- Special objects, which help (or hinder) you on the way. Activate them by including them in a match:
Bombs - stop the chain reaction and destory any gems on either side and above and blow it.
Wildcards - cause more chain reactions with adjacent pieces.
Stopwatches - freezes the gems so no more appear from the top for a few seconds, giving you precious time with which to clear more of the screen!
- Progressive levels. More gems when you start, and less time before new ones appear.
- Expert levels. Levels 15 to 20 have twice as many different colored gems as levels 1 to 14, making it even more difficult to get matches!
- Play with keyboard, joystick, or mouse.
- Beautiful graphics, most 3D rendered
- Stereo music and sound effects.
- Includes source code for both Gem Drop X (in C, using libSDL), as well as the original "Gem Drop" code (in Action!, for the Atari 8bit)!

Ruben provides Maven 2.x plugins for Ruby builds. It currently provides the bare basics for building Ruby classes with Maven 2.x.
Ruben project runs Ruby Unit Tests and fails builds if the unit tests do not pass. It also does dependency resolution, but this does not include transitive dependencies (so you will need to include every dependency in the pom.xml file) nor does it include downloading from a remote repo.
Enhancements:
- This is a minor release that includes transitive dependency resolution and gem packaging support.

Snes9X is a Super Nintendo Entertainment System emulator.
Snes9x is a portable, freeware Super Nintendo Entertainment System (SNES) emulator.
It basically allows you to play most games designed for the SNES and Super Famicom Nintendo game systems on your PC or Workstation; which includes some real gems that were only ever released in Japan.
Main features:
- ability to save in any location of the game, despite how the game was designed its amazingly useful when you dont want to redo the same level over and over.
- built-in peripherals. This is anything from multi-taps, to super scopes, to cheat devices.
- ability to rip sprites and music for your own personal use
- easier to organize and no stacks of cartridges that scare off non-nerdish women.
- filters can be used to enhance graphics on old games.
Snes9x is the result of well over three years worth of part-time hacking, coding, recoding, debugging, divorce, etc. (just kidding about the divorce bit). Snes9x is coded in C++, with three assembler CPU emulation cores on the i386 Linux and Windows ports.
Currently there are many ports of Snes9x available, please check the download page to see if a port exists for your system.
Enhancements:
- Pseudo-hires rendering flush, Old 2xsai endian fix
- Added oops auto-snapshot support

- Fixed JMA options in config
- Removed --with(out)-asmcpu option in config because the i386 assembler CPU core is out of date.
- Changed the default settings in config.
- Ported Snes9x to AMD64.
- Completed DSP-1 code.
- Updated DSP-3 and DSP-4 code.
- Fixed a lot of bugs.

Yet Another Time Machine is a command line Ogg Vorbis and MPEG audio player with the ability to control the tempo of playback without changing the pitch.
Primary usage would be to listen (for example) to audio books at 150% tempo. This is still understandable and saves time, hence the name of the program.
The following audio encoding formats are supported:
- Ogg Vorbis
- Ogg Speex
- MPEG
- All formats supported by libsndfile (FLAC, WAV, AIFF, ...)
Enhancements:
- Version 0.4 adds support for libsndfile.
- There is also an undocumented gem, you can use < and > to slow down or speed up by 10%, and hitting SPACE can be used to pause playback.

EasySok project is a sokoban game for KDE3.
In sokoban you are a warehouse keeper which has to push gems on their goals. The problem is, that the keeper can only push one gem and there are walls which stand in his way.
Sokoban was originally invented in 1982 by Hiroyuki Imabayashi at the Japanese company Thinking Rabbit, Inc. Sokoban has a (relatively) small, but very active group of fans around the world, which permanently create new levels and sokoban programs, so its unlikely that youll run out of new material.
If you dont use KDE3, just look at the link section, to find programs which are supported on your favorite platform (there are versions for Windows, Mac, PalmPilot, DOS and several Java programs, so you should find a program which you can use).
Main features:
- Playable with mouse or keyboard (or both).
- Automatically saves the last attempt for each map and all solutions.
- The best solutions for each level can be send to a highscore server and compared with the solutions of other users. The solutions are compared by the minimum number of pushes, the minimum number of linear pushes, the minimum number of gem changes and the minimum number of moves.
- A retro mode. In this mode you play the game backwards, starting from the end position. This allows you to quickly determine, in which order you have to push the gems on the goals.
- Saving and loading of games, level collections and solutions.
- A map editor, which lets you create your own maps and collections. It has also very limited support for auto generation of maps.
- Export a map as an image.
- Export a game either as an MNG-animation.
- An easy way to find duplicate maps.
- Annotation of solutions.
- Bookmarks for fast switching between games. You can also import your old KSokoban bookmarks.
- Unlimited undo/redo.
- You can let your moves be played.
- You can optimize your solutions for the number of moves or pushes made. This can also be done automatically for you.
- A basic solver (its not really clear, if this is a feature or a misfeature).
- You can change the look of the game by themes (currently the number of themes is really quite small).
- You can let the game honor dead fields (which are fields, where no gem should ever be positioned, because it cannot be moved to a goal from there). Depending on the theme, this dead fields are also marked. You have to try it, to really appreciate it!
- You can also let the programm show you all valid gem pushes.
- Its highly configurable.
Enhancements:
- Fixed configuration of toolbar.
- Made toolbar hidable.
- Updated admin dir to kde3.3 version.
