2 PCSX-ReARMed - yet another PCSX fork, ARM special
4 http://notaz.gp2x.de/pcsx_rearmed.php
10 PCSX ReARMed is yet another PCSX fork based on the PCSX-Reloaded project,
11 which itself contains code from PCSX, PCSX-df and PCSX-Revolution. This
12 version is ARM architecture oriented and features MIPS->ARM recompiler by
13 Ari64, NEON GTE code and more performance improvements. It was created for
14 Pandora handheld, but should be usable on other devices after some code
15 adjustments (N900, GPH Wiz/Caanoo, PlayBook versions are also available).
17 PCSX ReARMed features ARM NEON GPU by Exophase, that in many cases produces
18 pixel perfect graphics at very high performance. There is also Una-i's GPU
19 plugin from PCSX4ALL project, and traditional P.E.Op.S. one.
25 './configure && make' should work for the most part.
27 When compiling for ARM, it's advisable to tell configure script the CPU, FPU
28 and ABI that matches your target system to get best performance, like this:
30 CFLAGS='-mcpu=cortex-a8 -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp' ./configure
32 Cross compilation should also work if kernel-style CROSS_COMPILE variable
34 CROSS_COMPILE='arm-none-linux-gnueabi-' ./configure
40 There are several different frontends that can be built from source (one
41 generic and several platform specific), so usage slightly differs depending
42 on that. Most of them have a menu that can be used to run games and configure
45 Supported CD image formats:
52 - .ZNX/.ZNX.table (partial)
53 - EBOOT.PBP (PSP, partial)
56 CDDA (CD audio) only supported when .cue/.toc/.ccd/.mds files are present.
57 There is support for redump.org .sbi files, which can be used instead of
58 .sub files to save space (name it the same as .cue/.bin, just use .sbi
59 extension). This is required for Libcrypt copy protected game support.
61 The emulator can simulate BIOS, which means BIOS files are not required,
62 however implementation is not complete and some games still need real BIOS
63 to work. To use real BIOS, copy uncompressed BIOS files to bios/ directory
64 which itself should be in main emulator directory.
66 For pandora, it should be:
67 [sd card]/pandora/appdata/pcsx_rearmed/bios/
69 When the file is copied, BIOS should be selected in Options->BIOS/Plugins menu.
71 On pandora, analog controllers are supported using nubs, but this is
72 disabled by default and needs to be enabled in 'Controls' menu.
73 There is also touchscreen based GunCon support, which also requires
74 appropriate controller selected in controls configuration.
80 GPU (graphics) and SPU (sound) plugins can be selected in
83 builtin_gpu - this is either Exophase's ARM NEON GPU (accurate and fast,
84 available if platform supports NEON, like on pandora),
85 gpu_peops or gpu_unai (depends on compile options).
86 gpu_peops.so - P.E.Op.S. soft GPU, reasonably accurate but slow
87 (also found with older emulators on PC)
88 gpu_unai.so - Unai's plugin from PCSX4ALL project. Faster than P.E.Op.S.
89 but has some glitches.
90 gpu_gles.so - experimental port of P.E.Op.S. MesaGL plugin to OpenGL ES.
91 Occasionally faster but has lots of glitches and seems to
92 be rather unstable (may crash the driver/system).
93 builtin_spu - P.E.Op.S. SPU plugin, optimized for ARM.
94 spunull.so - NULL plugin, i.e. no sound emulation.
95 May cause compatibility problems.
101 PCSX and cwcheat cheat formats are supported. PCSX .cht file can be loaded from
102 "extra stuff" menu after game is loaded, while cwcheat cheats are automatically
103 loaded from cheatpops.db file, if one is present in emulator's directory and
104 has any cheats for the loaded game in it.
105 If any of those files are successfully loaded, 'cheats' option will appear in
106 the main menu where it is possible to enable/disable individual cheats.
