Just an update – still waiting on my replacement Tufty 2040 (post is never fast), however I managed to dig up my other [broken] Tufty 2040 - the one with the detached USB port.
Well… through determination and very steady hands, electrical tape also helped, I managed to firmware update the device to the latest (v.1.21.0) and copy all of the files [I’ve updated since I got the new one [aka: the one in this thread]] and still have the same problem - PicoVector Fonts do not display on the unit. Same gray/black screen. RiverRaid shows pixelated boxes for the ships, airplane, etc.
Could someone do me a favour, and please paste in a simple PicoVector Font script, tested to work on a Tuffty 2040, which I can run with.
