Peter Wendrich has released a new core for the C-One. Some of the improvements are: Partial support for the cartridge port on the C-One. (This needs a small modification of the PCB.) Rewritten large parts of the VIC-II code. Now it properly supports delayed-dma tricks. Sprite-stretching is correct. 9th sprite is displayed on correct position in the Krestage 3 demo. Timing between $D020 and screen pixels is cycle correct. Fixed bug in keyboard matrix and merged Mark McDougall's keyboard extensions. Lots of small fixes to the CPU.
