-PCSX-ReARMed - yet another PCSX fork
+PCSX-ReARMed - yet another PCSX fork, ARM special
http://notaz.gp2x.de/pcsx_rearmed.php
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).
+adjustments (N900, GPH Wiz/Caanoo, PlayBook versions are also available).
-PCSX ReARMed features GPU plugin from PCSX4ALL project.
+PCSX ReARMed features ARM NEON GPU by Exophase, that in many cases produces
+pixel perfect graphics at very high performance. There is also Una-i's GPU
+plugin from PCSX4ALL project, and traditional P.E.Op.S. one.
+
+
+Compiling
+---------
+
+For libretro build, just doing "make -f Makefile.libretro" is recommended as
+it's the way libretro team is building the core and only Makefile.libretro is
+maintained by them.
+
+For standalone build, './configure && make' should work for the most part.
+
+When compiling for ARM, it's advisable to tell configure script the CPU, FPU
+and ABI that matches your target system to get best performance, like this:
+
+CFLAGS='-mcpu=cortex-a8 -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp' ./configure
+
+Cross compilation should also work if kernel-style CROSS_COMPILE variable
+is set:
+CROSS_COMPILE='arm-none-linux-gnueabi-' ./configure
Usage
-----
-This version features a framebuffer driven menu that can be used to run
-games and configure the emulator.
+There are several different frontends that can be built from source (one
+generic and several platform specific), so usage slightly differs depending
+on that. Most of them have a menu that can be used to run games and configure
+the emulator.
Supported CD image formats:
- .bin/.cue
- .bz/.bz.table
- .ZNX/.ZNX.table (partial)
- EBOOT.PBP (PSP, partial)
+- .cbn
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
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
+to work. To use real BIOS, copy uncompressed BIOS files to bios/ directory
+which itself should be in main emulator directory.
+
+For pandora, it should be:
[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.
+When the file is copied, BIOS should be selected in Options->BIOS/Plugins menu.
+
+On pandora, 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.
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.
+builtin_gpu - this is either Exophase's ARM NEON GPU (accurate and fast,
+ available if platform supports NEON, like on pandora),
+ gpu_peops or gpu_unai (depends on compile options).
+gpu_peops.so - P.E.Op.S. soft GPU, reasonably accurate but slow
+ (also found with older emulators on PC)
+gpu_unai.so - Unai's plugin from PCSX4ALL project. Faster than P.E.Op.S.
+ but has some glitches.
+gpu_gles.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.
+ be rather unstable (may crash the driver/system).
+builtin_spu - P.E.Op.S. SPU plugin, optimized for ARM.
spunull.so - NULL plugin, i.e. no sound emulation.
+ May cause compatibility problems.
+
+
+Cheats
+------
+
+PCSX and cwcheat cheat formats are supported. PCSX .cht file can be loaded from
+"extra stuff" menu after game is loaded, while cwcheat cheats are automatically
+loaded from cheatpops.db file, if one is present in emulator's directory and
+has any cheats for the loaded game in it.
+If any of those files are successfully loaded, 'cheats' option will appear in
+the main menu where it is possible to enable/disable individual cheats.
Changelog
---------
+r21 (2015-01-12)
++ general: added ability to run SPU emulation on a separate thread, enabled it
+ by default when multicore CPU is detected. Significant effort was made to
+ avoid any compatibility problems which the old P.E.Op.S. implementation had.
++ pandora: added ability to run SPU emulation on TI C64x DSP by using bsp's
+ c64_tools.
+* libretro: fixed win32 build (mingw only)
+* some tweaks for the scanline effect and other things
+
+r20 (2014-12-25)
+* fixed various sound accuracy issues, like effects in ff7-ff9
+ for standalone build, audio will no longer slow down when emu is not fast
+ enough and stutter instead, as the former behavior causes accuracy issues.
+ Old mode can be restored in SPU plugin config options, but is not recommended.
+* savestates now save small parts of dynarec state to reduce dynarec related
+ slowdowns after savestate load
+* menu: fixed file browser issues with filesystems like exfat-fuse
+* menu: memcard manager: selected card is saved in config now
+* standalone: added some basic scanline efect
+* some CD image loading fixes
+* converted asm code to be compatible with more assemblers, like Apple's gas
++ libretro: added Makefile.libretro and support for various platforms like
+ iOS and QNX. Makefile.libretro is recommended way to do libretro builds
