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_unai_old.so- Unai's plugin from PCSX4ALL project. Faster than P.E.Op.S.
+ but has some glitches (old version).
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 driver/system).
Changelog
---------
+r24 (2024-01-22)
+* HLE compatibility has been greatly improved
+* various compatibility and accuracy improvements
++ support for more lightgun types
+- savestates from older versions might not work, especially if HLE was used.
+ Memory card files remain fully compatible.
+* many small changes I forgot about
+
+r23 (2022-03-14)
+* many fixes from various contributors on github and from the libretro fork
+* dynarec related slowdowns have been greatly reduced
+* many dynarec bug fixes
++ added chd disk image support
+
+r22 (2015-02-05)
+* general: fixed a race condition/crash in threaded SPU mode
+* pandora: C64x: fixed compatibility with newer c64_tools, enabled L2 cache
+* frontend: fixed control config corruption on load for devices that are
+ disconnected on startup
+* some dma accuracy improvements, might fix occasional glitches in ff7
+* ARMv6 build and the dynarec now make use of available instructions (gizmo98)
+
+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
