A new version of DSP, an emulator for various computer systems including the Amstrad CPC, is now, after a long time of development, available. You can download the new version from the DSP homepage.

Changes:

Added Motorola 68000 CPU!
• General
   +BUG: Fixed a stupid bug when looking for automatic updates.
   +BUG: When you select the list of drivers the current driver pause and stays in the background
   +BUG: Fixed joystick.
   +BUG: M6809 – At last! Fixed the last bugs in the M6809 core and G’n’G works correctly, the music on the Express Rider, Super Basketball, etc
   +NEW: M68000 – New CPU core, with many bugs but enough for some drivers from starting up.
   +ENHANCE: NEC765 – Implemented ‘Hexagon’ protection and other improved features, more games now load
   +ENHANCE: Added functions for generic moving of 8, 16 and 24 bits for the decryption of ROMs (Popeye, Toki, etc)
   +NEW: Added Z80CTC and Z80PIO devices, still very basic and not working so well (for the sound of StarForce and Sega System 1/2)
   +ENHANCE: Organized files of source code for more clarity.
   +BUG: Fixed when trying to boot a driver without the ROMs, DSP error gave one exception
   +ENHANCE: Fullscreen mode implemented in a rudimentary way. You must restart the emulator to change to full screen (first select ‘Full Screen’ mode, and then restart emulator), and with the keys ‘ALT-TAB’ you can change from the emulator to main screen.
