    • Multiple Arcade Machine Emulator for the PSP.



    • Fixed from 4.9r1
      - Usermode builds now works.
      - Dipswitches settings added.
      - Some Z80 core speedups.
      - Vector based games like Asteroids now run at native resolution of 480×272 pixels.
      - Preliminary memory management to clean-up things in certain romset (due to original MAME bugs) before starting a new emulation.
      - In case of memory fragmentation errors emulator now quits without lockups.
      - Better sound support in certain games, like Teenage Mutant Hero Turtles etc.
      - Graphics themes disabled in 1.50 kernel mode to gain more memory available, used a simple blue gradient instead.
      - Graphics mode saved with settings.

      Fixed from 4.7r3 (same as 4.8r1 unreleased)
      - Crash when sampled used.
      - Unified builds, thanks to new Z80 core, Mame 0.53 based, compatible with system16, neogeo and classic roms.
      - Implemented PSP-2000 (slim) specific support, so double memory available to load roms, thanks to keiich-san code.

      Fixed from 4.7r2:
      - Sounds now are near arcade perfect, with minor gliches in some sound chips emulations;
      - Gold (CPS1, System16 and Neogeo) specific emulations are now stand-alone, as require different z80 cpu implementation;
      - Improved performance with sounds, oldies with 0 frame skip and vsync on, others with auto-1 and auto-2;

      Fixed from 4.7:
      - 133 MHz in menu and while paused, for battery saving;
      - VSync really works now;
      - Corrected build configuration and Makefile, so sounds in various games are now back;
