fujprogfrom source on 24/8 on Catalina 10.15.3, using the provided CMake build script(s). This binary works for me on Catalina without sudo. The same binary also works for me on Mojave and High Sierra. I do not have a 3.0.8 board to test with. Over the last month this build of fujprog has worked for me without issues.
BTW on FB textmode and colors, do vt100 color numbers 100-108 work, they are "bright" versions of normal text bg colors 40-49. Visually it colors appear identical as non-bright... Well it's just for tetris, and generally completely unimportant :)
that's correct, due to IBM PC legacy, linux console doesn't support the bright background colors as separate color, the trick was always to use blink (SGR parameter 5), this sets the attribute bit in question
