-GINGE - Ginge Is Not GP2X Emulator
-
-(C) notaz, 2010
-http://notaz.gp2x.de/
-
-
-About
------
-
-Ginge is an application that can run many GP2X F100/F200 games on other ARM
-Linux platforms, which currently includes Wiz. It is not a full hardware
-emulator like MAME, PicoDrive or similar, it does not emulate the CPU. It can
-be considered as compatibility layer similar to Wine on PC Linux, however it
-does emulate small portion of MMSP2 system-on-chip. It operates by hooking
-certain system calls and using realtime patching of code that accesses memory
-mapped hardware directly.
-
-
-Usage
------
-
-Ginge comes with a launcher that is started when you run Ginge. The launcher
-can then be used to start GP2X software, which will either run if it's
-compatible, or just return back to the menu if it is not. In some cases it
-might hang though.
-
-
-Structure
----------
-
-Ginge actually consists of 4 independent executables and a few scripts:
-
-+ ginge_sloader - loader of static executables
-+ ginge_dyn     - dynamic executable handler
-+ ginge_prep    - .gpe parser that selects the right handler from above
-+ gp2xmenu      - the launcher/menu program
-+ ginge_dyn.sh  - environment setup script for ginge_dyn
-+ ginge.sh/gpe  - menu launcher script
-
-The menu is optional and can be replaced or bypassed completely. The only thing
-it does is running ginge_prep on GP2X .gpe program, ginge_prep handles the rest.

-Remaining portion is released under custom closed source license. It is not
-derived from gp2xmenu and is completely standalone, the menu is only included
