Here is the final version of PSPSim the SamCoupe Emulator for PSP. SimCoupe emulates a SAM Coupe – an 8-bit, Z80-based home computer released in 1989 by Miles Gordon Technology.

Changes:

– Many optimizations to speed up the emulation in
z80, video and sound emulation part.
Many games are now fullspeed (50 fps) even at 222Mhz !!
– Many new render modes and screen size options
(normal, fit, max etc …)
– The emulator window can now be moved to fit the screen properly
– Add new hotkeys to setup render mode etc …
– Bug fix in the low battery watchdog
– RTrigger/LTrigger keys can be used in the keyboard
settings menu to navigate between Normal, LTrigger
and RTrigger compose mapping.
– Default Hotkeys can now be set in the keyboard mapping menu
(useful to add hotkeys on existing/previous keyboard files)
– Code cleaning
