Free game platform emulators software for linux

Golly project is an open source, cross-platform Game of Life simulator currently under development by Andrew Trevorrow and Tomas Rokicki.
Our goal is to write a world-class Life simulator, solicit ideas and help from the planets best Life hackers, and share some of our excitement.
Main features:
- Unbounded universe (limited only by memory).
- Fast, memory-efficient conventional algorithm.
- Super fast hashing algorithm for highly regular patterns.
- Responsive even while generating or garbage collecting.
- Reads RLE, Life 1.05/1.06, and macrocell formats.
- Can paste in patterns from the clipboard.
- Auto fit option keeps patterns sized to the window.
- Full screen option (no menu/status/tool/scroll bars).
- Built-in HTML help system (thanks to wxWidgets).
Enhancements:
- The X11 version of Golly has a number of bugs and limitations, so use the GTK version if you can (it requires GTK+ 2.x).
- If you want to build Golly from the source distribution then to avoid various bugs use wxGTK 2.7 or later.

Jagacy 3270 Emulator is a feature-rich 3270 terminal emulator. It supports SSL, TN3270E, and over thirty languages. The project does not contain the screen-scraping library, and is a cost effective solution for a stand-alone Java 3270 terminal emulator.
The emulator can be configured to help create screen-scraping applications. Developers can also develop their own custom terminal emulators (with automated logon and logoff). Jagacy 3270 screen-scraping is faster, easier to use, and more intuitive than HLLAPI. It excels in creating applications reliably and quickly.
Main features:
- 100% pure Java.
- Feature rich 3270 terminal emulator.
- SSL support.
- Extended TN3270 (TN3270E) support.
- 17 different terminal types (including 132 columns).
- Internationalization support. Over 30 different languages supported.
- Configurable using properties, if desired. No changes necessary when host name or screens change.
- Easily create a custom 3270 terminal emulator.
- Small footprint (less than 150K). Runs efficiently within the Eclipse and NetBeans IDEs.
- Can display the 3270 session in a window while an application is running.
- Includes a full-featured 3270 terminal emulator tailored to developing and debugging applications.
Enhancements:
- Add features/limitations/changes here

Worminator 3 is akin to many Apogee Software and ID Software classic action games such as Duke Nukem and Commander Keen.
In Worminator game, you play as The Worminator (or as several other optional characters) and fight your way through many levels of madness and mayhem.
It features nine unique weapons, visible character damage, multiple supported resolutions, full screen scrolling, sound and music, and more.
Original Worminator story...
The year is 2028, 14 years after the start of the deadliest war in the history of worm kind. Much has changed... In the year 2012; a brilliant American scientist discovered how to make W.O.R.M. (Wormborg Operated Remote Missile) Weaponry, and to work them, the "WormBorgs" cyborg fighting machines.
These so called "WormBorgs" were the elite fighting force and the pride of the United Worms of America. Their life-like roles soon became far too life-like. They thought on their own, and acted on their own whims, under their own leader "DirtNet." No one exactly knows who or what "DirtNet" is, but it soon began to take over.
First, it launched the W.O.R.M.s at the Woroviet Union, in the hopes that they would retaliate and initiate a war between the Woroviet Union and the UWA. However, "DirtNet" obviously had a few bugs to work out, and the W.S.S.R was obliterated into millions of radioactive hunks of mud and dirt. Despite the fact that no one liked Wormunism anyway, all of Wormurope retaliated against the UWA.
Soon, the world was turned into a nuclear wasteland. Nuke drops became daily ordeals, and the giant bombs turning whole forests into matchsticks was to be expected. As if the sewers werent loaded with enough mutated alligators as it was, the hunks of radioactive material combined with the primordial soup of the sewers are said to have created blobs of sewage ooze, powerful enough that they fed off the mutated alligators for lunch.
After what was left of Wormurope had realized what tricks had been played on them by "DirtNet," they began to rally and fight back. For 8 years, the WormBorgs dominated the lands, crushing the rebels... until one faithful day, when the now famous rebel hero emerged. It was Wrom Conner.
No longer acting as individual factions, countries or nations, the rebels struck quickly and fiercely under Wroms command, using tactics that even the powerful W-1000s processors could not predict. The tide of the war had turned.
Over the next 5 years, the rebels devastated the WormBorgs. Using guerilla tactics and reprogrammed WormBorgs to fight for them, the rebels were a resourceful army indeed. Now, in desperation, "DirtNet" has just brought its proto-type WormBorg online, equipped with the latest in armor and weaponry, in one last attempt to regain control...
Main features:
- Fast, fluid scrolling
- 12 unique weapons, and many types of ammo
- Lots of gibs and shrapnel (all cartoonish, though)
- Visible character damage (as you get hurt, the Worminator actually becomes bloody)
- Visible weapons (every weapon actually appears differently on the Worminator. Most platform games have a single weapon graphic that shoots every type of projectile)
- Over 12 fully animated enemies

- Many sound effects (All from Internet sites such as Sound America and Meanrabbit. Let me know if there are any copyright problems, and I will deal with them immediately)
- Parallax scrolling, plus four data layers in every map. This makes the engine very flexible
- Game includes a campaign game with special scripted events, as well as an option to load custom maps
- Stereo sound effects (where available)
- Limited skins support; you can play as different characters!
- Built using Allegro + DJGPP. Source code may be made available if the demand is there
- If you wish to use the Worminator engine, contact me and we will discuss it (I would never charge any money for it, so if your interested, drop me an email. You have nothing to loose)
- Totally Freeware!
Enhancements:
- made worminator compile and run on Linux (Unix)
- made worminator yield the cpu when its idle
- save settings in textfile format under $HOME/.worm3.cfg instead of as binary blob in cwd
- save / load game to / from $HOME/.worm3.sav
- load datafile from DATADIR as defined during compilation instead of from cwd
- speedup: dont redraw borders and statuspanel unless nescesarry
- check all file accesses and give an error and continue when possible instead of just segfaulting
- fix a crash when changing audio options after loading a savegame of a custom-level or the tutorial
- fix a crash (unix only?) when changing video options and one similar on exit
- fix crash on exit caused by a few double frees on exit
- dont ask for confirmation on load/play_demo/exit when their is no game in progress
- show a message when trying to save when no game is in progress, instead of just silenty ignoring the request
- when clicking on another submenu when in one not only close the current one, but also open the new one
- fix map / savegame / demo read/write routines so that they work on Big Endian archs like PPC too

ClanBomber is a free (GPL) Bomberman-like multiplayer game that uses ClanLib, a free multi platform C++ game SDK. First "ClanBomber" was only a working title for a small game started in September 1998, that has only been started to learn how to use ClanLib.

But the ClanBomber project has grown into a real game. It is fully playable and features Computer controlled bombers, however, it is recommended to play ClanBomber with friends (3-8 players are really fun).

RealmForge project is a cross-platform 3D game engine for .NET.
RealmForge is a .NET 3D game engine predecessor to Visual3D.NET (www.visual3d.net), which is a framework and toolset for the visual design and development of 3D games, simulations, and interactive environments using C#, .NET 2.0, visual scripting, and the XNA Framework.
Enhancements:
- Access InGame Editor
- Press F11 with any application to toggle the InGame Editor on and off for editing games at runtime
- Controllerbased Input
- Intuitive componentbased input handling and behaviors that are easily extended
- Support for Editor/DevTool Plugins
- Devtools have been factored out of WorkspaceManager and are organized as simple and extendible or plugins
- Input focus fix
- Input isnt handled when working with the devtools
- Clicking on the render window will remove focus from devtools, enabling input again
- DragDrop Scene Creation
- Drag templates from the Scene Object Templates window onto the Scene window
- Reorganize the scene graph in the scene window and the templates in the Scene Object Templates window
- Click on nodes in the Scene window to select them
- Property Editing:
- Select nodes by clicking on them in the render window or Scene window and edit their properties in the Properties window (Property Inspector)
- Select components (such as the rendering engine or application) from the Components menu in the InGame Editor to edit their properties
- The properties are grouped and have descriptions and any custom properties added will show up as well
- New properties and ways of editing properties (especially collections) will be added in the future as well as fixes for properties like Orientation angles, Absolute Position, Direction, etc that may not work properly at the moment.
- About Box:
- The Help > About RealmForge GDK menu item now shows the About Box properly with information about the project and its developers.
- Event Editing:
- Click on the "View > Event Scripting Designer" menu item to work with the designer to visually script events
- Selecting a target from the dropdown list and an event from the list right below it
- Drag scripts from the Tree of all scripts or from the list of named delegates
- Add any method in the entire framework or from plugins that has a void SimpleMethod() or void Script(object owner, object args) signature by specifying the fully qualified (include namespace) class name and members (fields and properties) that need to be traversed to get to it from a static member of that class
- You can leave the class name empty an will default to the RealmForge.RF, the singleton aggregator.
- Saving your game:
- The File > Save menu item now actually works and will save the current scene (for applications that load the scene from a master module, doesnt work for the Sample Browser tech demos yet). This feature is buggy and verbose, however since it is finally supported it wont be long before the editor will be fully usable for game development!

Wyrm Tools is a suite of tools to make your gaming more productive regardless of which rules system you use. More importantly, Wyrm Tools is an RPG tool platform.

While this project anticipates to offer the standard RPG tool fare (such as a character generator and editor), it gives users the flexibility to add their own tools, even to the point of defining their own game systems.

The foundation of Wyrm Tools is the Eclipse Rich Client Platform. Wyrm Tools is to be to RPGs what Eclipse is to, well, everything else.

The overall project has progressed to a pre-alpha release. The core platform functionality (i.e. the game system agnostic bits) are mature. Currently, the d20 3.5 game system is being implemented along with a d20 character editor.
