David Horrocks released an update of his Commodore 64 emulator. This time the following changes: Option to enable/disable opposing joystick directions. Speed optimisation to the CPU, CIA and VIC. The emulation is noticeable faster on lines with no DMA fetches and no IRQs. Bug fix to the reverse keyboard matrix. Accurate emulation of the $DD00 VIC bank switch bug. David is now working on the debugger.
