I am mainly interested in the old skool PC Core. I have a MiST and ZX-Uno but only the ZX-Uno has a PC Core, but mine only has 512Kb of RAM so the PC Core is very limited.
Being able to play SWOS perfectly with a pocket travel device on HDMI is also very interesting
I thought I read somewhere the AMIGA Core could be 68020 ? MiST has 68020 so it would be good if a WHDload setup could be run on the Flea.
I think it best to almost follow a RPi Zero guide which puts it in a NES cart, so that the ports are protected by extension leads. MicroSD ports are not the best for lots of plugging/unplugging.
It looks like sound out is through HDMI? Nice if you had option to route out via gpio pins to 3.5mm jack. Handy for using with DVI monitors.
