7 | About |
8 | ----- |
9 | |
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 |
3938f69a |
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 |
4ea086f6 |
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. |

22 | Compiling |
23 | --------- |
24 | |
25 | './configure && make' should work for the most part. |
26 | |
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: |
29 | |
30 | CFLAGS='-mcpu=cortex-a8 -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp' ./configure |
31 | |
32 | Cross compilation should also work if kernel-style CROSS_COMPILE variable |
33 | is set: |
34 | CROSS_COMPILE='arm-none-linux-gnueabi-' ./configure |
35 | |
36 | |

37 | Usage |
38 | ----- |
39 | |
06d2e1a5 |
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 |
43 | the emulator. |
303ee308 |
44 | |
33716956 |
45 | Supported CD image formats: |
f932e54b |
46 | - .bin/.cue |
47 | - .bin/.toc |
48 | - .img/.ccd/.sub |
49 | - .mdf/.mds |
303ee308 |
50 | - .Z/.Z.table |
33716956 |
51 | - .bz/.bz.table |
52 | - .ZNX/.ZNX.table (partial) |
53 | - EBOOT.PBP (PSP, partial) |
bab59f00 |
54 | - .cbn |
303ee308 |
55 | |
7ca0ce80 |
56 | CDDA (CD audio) only supported when .cue/.toc/.ccd/.mds files are present. |
900acfae |
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. |
303ee308 |
60 | |
c9dbba7f |
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 |
06d2e1a5 |
63 | to work. To use real BIOS, copy uncompressed BIOS files to bios/ directory |
64 | which itself should be in main emulator directory. |
65 | |
66 | For pandora, it should be: |
c9dbba7f |
67 | [sd card]/pandora/appdata/pcsx_rearmed/bios/ |
06d2e1a5 |
68 | |
69 | When the file is copied, BIOS should be selected in Options->BIOS/Plugins menu. |
c9dbba7f |
70 | |
b0c8d18b |
71 | On pandora, analog controllers are supported using nubs, but this is |
72 | disabled by default and needs to be enabled in 'Controls' menu. |
7ca0ce80 |
73 | There is also touchscreen based GunCon support, which also requires |
74 | appropriate controller selected in controls configuration. |

77 | Plugins |
78 | ------- |
79 | |
80 | GPU (graphics) and SPU (sound) plugins can be selected in |
81 | [BIOS/Plugins] menu: |
82 | |
c069dc1b |
83 | builtin_gpu - this is either Exophase's ARM NEON GPU (accurate and fast, |
06d2e1a5 |
84 | available if platform supports NEON, like on pandora), |
4ea086f6 |
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. |
c069dc1b |
89 | but has some glitches. |
4ea086f6 |
90 | gpu_gles.so - experimental port of P.E.Op.S. MesaGL plugin to OpenGL ES. |
ee78346e |
91 | Occasionally faster but has lots of glitches and seems to |
4ea086f6 |
92 | be rather unstable (may crash the driver/system). |
c069dc1b |
93 | builtin_spu - P.E.Op.S. SPU plugin, optimized for ARM. |
ee78346e |
94 | spunull.so - NULL plugin, i.e. no sound emulation. |
4ea086f6 |
95 | May cause compatibility problems. |
ee78346e |
96 | |
97 | |
9c27c205 |
98 | Cheats |
99 | ------ |
100 | |
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. |
