Quake!
This ports id Software's Quake to run on the SDL plugin runtime. The source code originated from id under the GPLv2 license. I used https://github.com/ahefner/sdlquake as the base of my port. Performance is, unsurprisingly, not on par with what you're probably used to on PC. I average about 10FPS on ipod6g, but it's still playable. Sound works well enough, but in-game music is not supported. I've written ARM assembly routines for the inner sound loop. Make sure you turn the "brightness" all the way down, or colors will look funky. To run, extract Quake's data files to /.rockbox/quake. Have fun! Change-Id: I4285036e967d7f0722802d43cf2096c808ca5799

+All of Quake's data access is through a hierchal file system, but the contents of the file system can be transparently merged from several sources.
+
+The "base directory" is the path to the directory holding the quake.exe and all game directories. The sys_* files pass this to host_init in quakeparms_t->basedir. This can be overridden with the "-basedir" command line parm to allow code debugging in a different directory. The base directory is
+only used during filesystem initialization.
+
+The "game directory" is the first tree on the search path and directory that all generated files (savegames, screenshots, demos, config files) will be saved to. This can be overridden with the "-game" command line parameter. The game directory can never be changed while quake is executing. This is a precacution against having a malicious server instruct clients to write files over areas they shouldn't.
+
+The "cache directory" is only used during development to save network bandwidth, especially over ISDN / T1 lines. If there is a cache directory
+specified, when a file is found by the normal search path, it will be mirrored
+into the cache directory, then opened there.
+
+
+
+FIXME:
+The file "parms.txt" will be read out of the game directory and appended to the current command line arguments to allow different games to initialize startup parms differently. This could be used to add a "-sspeed 22050" for the high quality sound edition. Because they are added at the end, they will not override an explicit setting on the original command line.

+
+cvar_t variables are used to hold scalar or string variables that can be changed or displayed at the console or prog code as well as accessed directly
+in C code.
+
+it is sufficient to initialize a cvar_t with just the first two fields, or
+you can add a ,true flag for variables that you want saved to the configuration
+file when the game is quit:
+
+cvar_t r_draworder = {"r_draworder","1"};
+cvar_t scr_screensize = {"screensize","1",true};
+
+Cvars must be registered before use, or they will have a 0 value instead of the float interpretation of the string. Generally, all cvar_t declarations should be registered in the apropriate init function before any console commands are executed:
+Cvar_RegisterVariable (&host_framerate);
+
+
+C code usually just references a cvar in place:
+if ( r_draworder.value )
+
+It could optionally ask for the value to be looked up for a string name:
+if (Cvar_VariableValue ("r_draworder"))
+
+Interpreted prog code can access cvars with the cvar(name) or
+cvar_set (name, value) internal functions:
+teamplay = cvar("teamplay");
+cvar_set ("registered", "1");
+
+The user can access cvars from the console in two ways:
+r_draworder prints the current value
+r_draworder 0 sets the current value to 0
+Cvars are restricted from having the same names as commands to keep this
+interface from being ambiguous.

+ memory allocation
+
+
+H_??? The hunk manages the entire memory block given to quake. It must be
+contiguous. Memory can be allocated from either the low or high end in a
+stack fashion. The only way memory is released is by resetting one of the
+pointers.
+
+Hunk allocations should be given a name, so the Hunk_Print () function
+can display usage.
+
+Hunk allocations are guaranteed to be 16 byte aligned.
+
+The video buffers are allocated high to avoid leaving a hole underneath
+server allocations when changing to a higher video mode.
+
+
+Z_??? Zone memory functions used for small, dynamic allocations like text
+strings from command input. There is only about 48K for it, allocated at
+the very bottom of the hunk.
+
+Cache_??? Cache memory is for objects that can be dynamically loaded and
+can usefully stay persistant between levels. The size of the cache
+fluctuates from level to level.
+
+To allocate a cachable object
+
+
+Temp_??? Temp memory is used for file loading and surface caching. The size
+of the cache memory is adjusted so that there is a minimum of 512k remaining
+for temp memory.
