I didn't have the header on the 12f I was using so had to solder one on.
What games are you running now?
I tried it with Grid Runner.
Just tried the C64 hdmi output through my hdmi capture card and I get a nice clear picture on the PC, but the pass thru signal from the device has noise on it, presumably due to the slightly strange signal frequency. So I should be able to capture the C64 output like I did for the SMS video.
So I now have the picture on 3 devices :)
@lawrie you can try slight changes in PLL frequency, in toplevel there are 2 PLL stages so very fine tune in clock around 32MHz is possible. Of course due to electrical incompatibility and phase offset between RGB and CLK it depends on video capture device will it have noise or be clean signal

@lawrie hi there is now c64 with st7789 quite good looking. Still paper is a bit off-screen at right side. Reducing x-size with divide by 6 instead of 5 as now would fit but font looks ugly then (commented in code). I'm thinking to center x fully and then blinking cursor will be off screen...
c64 is one of the harder retro computers to fit on the lcd as it is 320 pixels wide.
yes sms and probably nes too would be just fine with this lcd. Also I think ti99 and vic20 could work well, maybe apple2 too
I'm porting this to MiSTer and wondering if anyone would want to port to ulx3s https://github.com/menloparkinnovation/menlo_gigatron
@lawrie @Speccery I got ti99/4a display video on st7789. Complete text mode is visible, a bit of color stripes from title screen are cropped. For eventual pull I don't know is the implementation following style, as st7789 support is pulled out of sys module to toplevel https://github.com/emard/icy99
Here it is running Microsoft Basic:

It is an attempt to redo my Z80 retro computers with a common code base, starting with a template, and then adding the specifics for each computer or game console.
I am using @pnru_gitlab's 6850 ACIA implementation as the uart, as that is compatible with computers such as the RC2014
So I can run the roms from that project - https://github.com/RC2014Z80/RC2014/tree/master/ROMs/Factory
@emard would know that he tried
I think currently fastest way is using ESP32 to program it
@splinedrive external JTAG pins are there to connect external JTAG programmer. it can be much faster if fast software is used. I tried FT2232 with diamond, it works as native programmer but diamond programs FPGA slowly compared to other programmers using same FT2232 hardware... Goran uses ext JTAG during prototype troubleshooting when only FPGA is soldered onboard without any other parts onboard. Ext JTAG can be used if USB-FTDI and WIFI methods are not working or supported. I wanted that user never runs out of options to program ULX3S :)
