2PCSX-ReARMed - yet another PCSX fork
c9dbba7f 4
303ee308 6
10PCSX ReARMed is yet another PCSX fork based on the PCSX-Reloaded project,
11which itself contains code from PCSX, PCSX-df and PCSX-Revolution. This
12version is ARM architecture oriented and features MIPS->ARM recompiler by
3938f69a 13Ari64, NEON GTE code and more performance improvements. It was created for
14Pandora handheld, but should be usable on other devices after some code
b0c8d18b 15adjustments (N900, GPH Wiz/Caanoo versions are also available).
303ee308 16
c069dc1b 17PCSX ReARMed features ARM NEON GPU by Exophase, that in many cases produces
18pixel perfect graphics at very high performance. There is also Una-i's GPU
19plugin from PCSX4ALL project, and traditional P.E.Op.S. one.
303ee308 20
25This version features a framebuffer driven menu that can be used to run
26games and configure the emulator.
33716956 28Supported CD image formats:
f932e54b 29- .bin/.cue
30- .bin/.toc
31- .img/.ccd/.sub
32- .mdf/.mds
303ee308 33- .Z/.Z.table
33716956 34- .bz/.bz.table
35- .ZNX/.ZNX.table (partial)
36- EBOOT.PBP (PSP, partial)
bab59f00 37- .cbn
303ee308 38
7ca0ce80 39CDDA (CD audio) only supported when .cue/.toc/.ccd/.mds files are present.
900acfae 40There is support for .sbi files, which can be used instead of
41.sub files to save space (name it the same as .cue/.bin, just use .sbi
42extension). This is required for Libcrypt copy protected game support.
303ee308 43
c9dbba7f 44The emulator can simulate BIOS, which means BIOS files are not required,
45however implementation is not complete and some games still need real BIOS
46to work. To use real BIOS, copy uncompressed BIOS files to
47[sd card]/pandora/appdata/pcsx_rearmed/bios/
48then select the BIOS you want to use in Options->BIOS/Plugins menu.
b0c8d18b 50On pandora, analog controllers are supported using nubs, but this is
51disabled by default and needs to be enabled in 'Controls' menu.
7ca0ce80 52There is also touchscreen based GunCon support, which also requires
53appropriate controller selected in controls configuration.

ee78346e 56Plugins
59GPU (graphics) and SPU (sound) plugins can be selected in
60[BIOS/Plugins] menu:
c069dc1b 62builtin_gpu - this is either Exophase's ARM NEON GPU (accurate and fast,
63 available if platform supports NEON), else it's P.E.Op.S.
64 soft GPU (accurate but slow). - plugin from PCSX4ALL project. Faster than P.E.Op.S.
66 but has some glitches.
ee78346e - experimental port of P.E.Op.S. MesaGL plugin to OpenGL ES.
68 Occasionally faster but has lots of glitches and seems to
69 be rather unstable (may crash the system).
c069dc1b - P.E.Op.S. soft GPU (in case builtin one is NEON)
71builtin_spu - P.E.Op.S. SPU plugin, optimized for ARM.
ee78346e - NULL plugin, i.e. no sound emulation.
