Would it be possible to upload the gerber files you used to print the PCB to github? I see the KiCAD files but no gerbers. Thanks!

I've added gerbers, BOM and CPL files.

Yes, this week hopefully. Just waiting for a PCB delivery.

FWIW, only the first four signals are used by the Laggy, so just VBUS, D-, D+ and GND.

This round is pretty much sold out but I will have another batch soon. I will try selling through etsy also which I believe handles the various import duties.

This is cool! Will it only work on LCDs or can it also be used on CRTs?

It will work on CRTs, yes. It's a normal mister core so it outputs analog video along with HDMI.

Make sure there are no other IremM92 files in the _arcade/cores directory.

The Dream Soccer issue is known https://github.com/MiSTer-devel/Arcade- ... /issues/10

The In The Hunt issue is unrelated to this. Are you sure that all extra M92 rbf files have been removed?
