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;
