+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, GPH Wiz/Caanoo versions are also available).
+adjustments (N900, GPH Wiz/Caanoo, PlayBook versions are also available).
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
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.
+
+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.
[BIOS/Plugins] menu:
builtin_gpu - this is either Exophase's ARM NEON GPU (accurate and fast,
- available if platform supports NEON), else it's P.E.Op.S.
- soft GPU (accurate but slow).
-gpuPCSX4ALL.so - plugin from PCSX4ALL project. Faster than P.E.Op.S.
+ 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.
-gpuGLES.so - experimental port of P.E.Op.S. MesaGL plugin to OpenGL ES.
+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).
-gpuPEOPS.so - P.E.Op.S. soft GPU (in case builtin one is NEON)
+ 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
---------
+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
+ (patches from CatalystG, squarepusher, notaz and others, see git).
