Topic: Software emulation features possible with FPGA?

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?
