Me too. Life is too short. Similarly, although I accept that SDL2 emulator
must accept the mouse/kybrd event delivered by rPi, the documentation
<try this try that> indicates that it's not yet mature/stable for rPi.
Like *we* could spend much time getting LNO working on some
hardware, and then need to repeat the effort, on other hardware.
OTOH, LEO worked immediately, and I've been using it everyday
since. IMO risc.img + SDL2 is a clever acrobat, but fails the simplicity
Re. <a place for ETHO to live> if ETHZ can't guard our jewels:
I looked at your
All pdf. I don't like pdf.
I fetched <ARM compiler helicopter project> and 'cleaned'
some parts, for my new format: lying-down like a baby, and
having rPi read it to me via TestToSpeech.
