PCSX-ReARMed - yet another PCSX fork

http://notaz.gp2x.de/pcsx_rearmed.php


About
-----

PCSX ReARMed is yet another PCSX fork based on the PCSX-Reloaded project,
which itself contains code from PCSX, PCSX-df and PCSX-Revolution. This
version is ARM architecture oriented and features MIPS->ARM recompiler by
Ari64, NEON GTE code and more performance improvements. It was created for
Pandora handheld, but should be usable on other devices after some code
adjustments (N900 version is also available).

PCSX ReARMed features GPU plugin from PCSX4ALL project.


Usage
-----

This version features a framebuffer driven menu that can be used to run
games and configure the emulator.

Supported CD image formats:
- .bin/.cue
- .bin/.toc
- .img/.ccd/.sub
- .mdf/.mds
- .Z/.Z.table
- .bz/.bz.table
- .ZNX/.ZNX.table (partial)
- EBOOT.PBP (PSP, partial)

CDDA (CD audio) only supported when .cue/.toc/.ccd/.mds files are present.
There is support for redump.org .sbi files, which can be used instead of
.sub files to save space (name it the same as .cue/.bin, just use .sbi
extension). This is required for Libcrypt copy protected game support.

The emulator can simulate BIOS, which means BIOS files are not required,
however implementation is not complete and some games still need real BIOS
to work. To use real BIOS, copy uncompressed BIOS files to
[sd card]/pandora/appdata/pcsx_rearmed/bios/
then select the BIOS you want to use in Options->BIOS/Plugins menu.

Analog controllers are supported using nubs, but this is disabled by
default and needs to be enabled in 'Controls' menu.
There is also touchscreen based GunCon support, which also requires
appropriate controller selected in controls configuration.


Plugins
-------

GPU (graphics) and SPU (sound) plugins can be selected in
[BIOS/Plugins] menu:

builtin_gpu    - the P.E.Op.S. GPU plugin, most accurate but slow.
gpuPCSX4ALL.so - plugin from PCSX4ALL project. Faster but has some glitches.
gpuGLES.so     - experimental port of P.E.Op.S. MesaGL plugin to OpenGL ES.
                 Occasionally faster but has lots of glitches and seems to
                 be rather unstable (may crash the system).
builtin_spu    - P.E.Op.S. SPU plugin.
spunull.so     - NULL plugin, i.e. no sound emulation.

* some moderate builtin GPU and SPU optimizations
+ added redump.org SBI support
* tuned frameskip code again
* fixed one 'analog controller not working' issue
* fixed a crash in builtin gpu code
* fixed cdrom slowdown issue
* fixed my stupid bug in the recompiler that slowed down
  recompilation a lot
* some other refactoring

r6 (2011-02-10)
+ added analog controller support using nubs (disabled by default)
+ added control config saving
+ added support for ingame actions (eg. savestate load)
