It looks like a problem with the active converter. I'll have a play with loader and see if I can reproduce it.

<![CDATA[SID talk]]> https://www.fpgaarcade.com:443/punbb/viewtopic.php?id=256&action=new It something I keep meaning to go back to. We have improved the RTL to match the schematics a little better, and we have a lot of extracted layout data now to work with.

The issue is still how to model the analogue bits sufficiently well in an FPGA.

<![CDATA[Cycle exact TED chip]]> https://www.fpgaarcade.com:443/punbb/viewtopic.php?id=1207&action=new Hi Istvan and welcome. Looks great.
I've looked at the TED schematics for years but never found the time or enthusiasm to work on it.
I would love to include your core in our ecosystem if that's ok.
btw you are more than welcome to join us on the slack group.

<![CDATA[Software emulation features possible with FPGA?]]> https://www.fpgaarcade.com:443/punbb/viewtopic.php?id=1378&action=new I really love FPGAs for their baremetal nature, but I do wonder whether it would be possible in theory to implement some of these useful software emulation features:

- Black Frame Insertion (BFI) for reducing motion blur: https://emulation.gametechwiki.com/inde … _insertion

- Quick Frame Transport (QFT) for latency reduction: https://forums.blurbusters.com/viewtopic.php?t=4064

- Run-Ahead for latency reduction: https://arstechnica.com/gaming/2018/04/ … -consoles/

- Overclocking without speeding up the video and audio: https://arstechnica.com/gaming/2019/08/ … rclocking/ (people in the comment section there even started discussing whether it is possible with FPGAs)

- more advanced CRT/LCD filters, for instance: https://mattiasgustavsson.itch.io/dosbox-crt (a filter for DOS, and there actually is an open-source FPGA DOS core, so this could be useful)

And what features of software emulators do you miss the most?

<![CDATA[Hello from northern Germany]]> https://www.fpgaarcade.com:443/punbb/viewtopic.php?id=1377&action=new Hi and welcome!

Nice to learn that you were successful in setting up the Vidor and running cores.
Personally I also like the Vidor for being compact and cheap (Arduino.cc shop has special offer for it atm). Integration with Replay still has some edges but these should be ironed out in the future. It's amazing what's possible just out-of-the box though.

I'm especially glad that you reproduced the ZX Spectrum tape fix since it was a real bugger to track down and fix.

I'd guess a C64 should be feasible on the Vidor (don't quote me, I haven't actually looked into details).

Cheers from southern Germany smile
