| File Description Homebrew developer TTYman has just released a new PSP compatible build of emulator MAME4ALL, bumping it up to version 4.9r2 Hires. This specific program allows PlayStation Portable owners to run and play games released on the Multiple Arcade Machine Emulator. Anyway, a lot have changed since the last release so those who love playing old school arcades games on the go should update to this version. TTYman provided the following changelog: * Usermode builds now works. * Dipswitches settings added. * Some Z80 core speedups. * Vector based games like Asteroids now run at native resolution of 480x272 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. TTYman added several documentation files to PSP MAME4ALL v4.9r2 Hires. Be sure to read those first before doing anything to avoid problems. The download package below contains the emulator itself, the emulator with MD5 checksum file, as well as the source codes for both. |
