Mistification from slingshot, many many many thanks!
basic mist ypbpr support
Split the concept of hsync, vsync and composite sync. When composite sync used tie vsync high. The offset hsync pulse of pal/hsync is only present for 15khz composite sync. Remove rom selection since its unused.
Missing entry in process sensitivity list
Press windows key to toggle paddle mode. Press alt to toggle scanlines.
Paddle on mist a800. Added NTSC palette. Added support for 4k and 8k roms to 5200 - need to wire up to cartlogic really...
These were cross connected - no idea why it was building. SD init gets further now, but still no dice.
Changed mist to use simulated sd card, rather than the custom protocol
Merged turbo freezer support from Hias. Working pretty well. PIA freezing not working yet though, so no joystick after freeze. Scoll lock to freeze.
Merged in first cut cartridge emulation support from Hias. Excellent:-)
Split PAL pll into two - now much closer to real frequency
Improved timings for PAL and NTSC
Add 32GB SD support
Connect up scanlines to spare mist dip switch!
Add some mist button support for keyboard less setups
Button 0=F11. Switched swapped joysticks. connected led to sio
Added scandoubler. Build some variants.
Added ZPU. Added read/write SD support. Fixed joystick. Switched to new mist keyboard mode (ps2 emulation).
Fixed turbo
Use video bits generic
Connected up SDRAM. Make 800XL core wait for SDRAM reset to complete. Also had to adjust phase offset to make it work - need to get a proper setup for mist
Wired up mist with internal ram/rom. Tested OK.
Current unmerged vhdl for my Atari800 core and start at merging them into one tree with a common core
