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
15adjustments (N900 version is also available).
303ee308 16
c9dbba7f 17PCSX ReARMed features GPU plugin from PCSX4ALL project.
303ee308 18
23This version features a framebuffer driven menu that can be used to run
24games and configure the emulator.
33716956 26Supported CD image formats:
f932e54b 27- .bin/.cue
28- .bin/.toc
29- .img/.ccd/.sub
30- .mdf/.mds
303ee308 31- .Z/.Z.table
33716956 32- .bz/.bz.table
33- .ZNX/.ZNX.table (partial)
34- EBOOT.PBP (PSP, partial)
303ee308 35
7ca0ce80 36CDDA (CD audio) only supported when .cue/.toc/.ccd/.mds files are present.
900acfae 37There is support for .sbi files, which can be used instead of
38.sub files to save space (name it the same as .cue/.bin, just use .sbi
39extension). This is required for Libcrypt copy protected game support.
303ee308 40
c9dbba7f 41The emulator can simulate BIOS, which means BIOS files are not required,
42however implementation is not complete and some games still need real BIOS
43to work. To use real BIOS, copy uncompressed BIOS files to
44[sd card]/pandora/appdata/pcsx_rearmed/bios/
45then select the BIOS you want to use in Options->BIOS/Plugins menu.
799b0b87 47Analog controllers are supported using nubs, but this is disabled by
48default and needs to be enabled in 'Controls' menu.
7ca0ce80 49There is also touchscreen based GunCon support, which also requires
50appropriate controller selected in controls configuration.

ee78346e 53Plugins
56GPU (graphics) and SPU (sound) plugins can be selected in
57[BIOS/Plugins] menu:
59builtin_gpu - the P.E.Op.S. GPU plugin, most accurate but slow. - plugin from PCSX4ALL project. Faster but has some glitches. - experimental port of P.E.Op.S. MesaGL plugin to OpenGL ES.
62 Occasionally faster but has lots of glitches and seems to
63 be rather unstable (may crash the system).
7ca0ce80 64builtin_spu - P.E.Op.S. SPU plugin.
ee78346e - NULL plugin, i.e. no sound emulation.
