Peter Wendrich has published the first C64 PAL core that is not considered to be alpha any more. CPU registers $0000 and $0001 are fixed now, CIA timers / TOD registers fixed, IRQ/NMI timing fixed. Peter is now accepting bug reports under the eMail address mentioned in the readme file. Tobias Gubener has released a new system flash that can now emulate a 1541 drive. The 1k30 FPGA can be fed with a new rom file containing the drive emulation code. Every core that uses the IEC port can make use of the emulation. Just hit F8 to get to choose the D64/PRG file.
