We have been working on improving the video output and timing of the MEGA65 lately. This includes getting HDMI video output at PAL 50Hz and NTSC 60Hz working. We now have the PAL mode working with exactly the right number of clock cycles per frame, and can even run the nasty freeze-combined.prg test programme from the VICE emulator test suite. The video frame is perfectly timed, but the CPU timing for bad lines is not yet perfect, so the inner part is not quite meta-stable. Also, freezing doesn't synchronise entry with exit when unfreezing, so the synchronisation of the bars in the border with those in the screen gets messed up (except when you are trying to show it ;)
