VICE - C64 C128 PLUS4 VIC20 Emulator for PS3 v1.0.2

EmuCR: VICE-PS3VICE - C64 C128 PLUS4 VIC20 Emulator for PS3 v1.0.2 are released. TimRex has released VICE (Versatile Commodore Emulator) for PS3, which is a C64, C128, PLUS4 and VIC20 emulator for PS3 JailBreak users.

Build 1.0.2 (08-12-2010):
-----------------------

- ReSID emulation optimised to use AltiVec instruction set, yielding significant performance boost
against higher quality audio emulation in resampling mode. We now achieve 100% C64 CPU clock at
the highest quality.

Resampling (20) 100% CPU (warp mode - 313%)
Resampling (50) 100% CPU (warp mode - 296%)
Resampling (70) 100% CPU (warp mode - 286%)
Resampling (90) 100% CPU (warp mode - 216%)

Even DualSid (SidStereo) mode at 90% Resampling yields 100% CPU (warp mode - 114%).

- Default ReSID quality now set to maximum (Resampling at 90% Band Pass)

- Resampling quality automatically decreases by 10% if any underrun occurs.
This generally kicks in when the Bloom or CRT filters are active.

- Fixed minor redraw bug that caused the screen buffer to flip back to settings screen after a blit timeout
- Added PIC1.PNG

- Support to insert a disk image without rebooting (TRIANGLE)

- Added compatibility SlowLoad mode (SQUARE)
This will disable FastLoad and enable True Drive Emulation (TDE) for those titles that require it
for improved compatibility

- Mapped RUN/STOP key to L3

- Mapped right control-stick to cursor keys (up/down/left/right)

- Fixed F1/F3/F5/F7 key mapping

- Finally... Disabling audio emulation altogether during warp mode has increased CPU throughput to 1749%
That ought to help any long load times.

- Optimised audio buffer sizes

- Added C128 support (VDC 80 column display is emulated, but not viewable)

Build 1.0.1 (04-12-2010):
-----------------------

- On-Screen Keyboard fixed.

- Initial support for ReSID emulation.
- Currently defaults to FastSID
Edit the vicerc file to enable Interpolation or Resampling methods.

SidResidSampling=0 // FastSID (default)

SidResidSampling=1 // Interpolation (better quality, slower)

SidResidSampling=1 // Resampling (best quality, slowest)
SidResidPassband=90 // Sets the frequency band percentage to apply resampling.

Performance Notes:
ReSID emulation is currently unoptimised for the CELL processor.
As such, performance at the BASIC prompt (when no sound is playing) yields the following real C64 CPU speeds.

FastSID 100% CPU (warp mode - 1143%)

Interpolation 100% CPU (warp mode - 352%)

Resampling (20) 100% CPU (warp mode - 196%)
Resampling (50) 100% CPU (warp mode - 195%)
Resampling (70) 100% CPU (warp mode - 117%)
Resampling (90) 33% CPU
