Realized I never looked at the video timings of Cave CV1000 back when I was looking at how the blitter worked, so went ahead and did that.
Results are at https://github.com/buffis/cv1k_research/tree/main/Video_Timings and they have been merged into MAME as of yesterday.
The quick summary is:
- Pixel clock: 6.4MHz
- Lines per frame: 262 (including sync)
- Lines of VSYNC: 3
- Active lines (rest is overscan): 240
- Pixels per line: 407 (including sync)
- Pixels of HSYNC: 29
- Active pixels per line (rest is overscan): 320
- Framerate: 60.0183806291 Hz (6,400,000 / (262 * 407)
For people emulating the games, this should not have any effect really. This is mostly for documenting the behavior of boards, and for people doing stuff such as custom video scalers.
