hi elinkser, i'm impressed you got it working - really nice work! i'd be glad to add your patches to support any other Kobo devices. i'm a bit confused, though, because i also have a Clara Kobo HD and i'm able to compile and run the rmkit apps on there - maybe it's different firmware? (or maybe its the ARCH vs TARGET issue?)
the one major app you are missing is remarkable_puzzles (
https://github.com/mrichards42/remarkable_puzzles), which is a port of simon tatham's puzzles. let me know if you want me to send you a compiled version.
the docs are a bit out of date, because if you use `TARGET=kobo make <project>`, it will compile the font into the binary itself. i will update that now.
let me know if there's anything i can do to help. glad to see people are trying out rmkit
