I have a pi0 but cannot get TZXs to load
You will require a new updated dot/pisend and nextzxos/tzxload.bas from the git : https://gitlab.com/thesmog358/tbblue These need to be place in the correct folders on your SD card. These files have updated after the distro was released. You can check if the pi0 is correctly responding by going into Command Line and running “.term” You should see Terminex, press SYM+SHIFT+B to switch to 115,200 baud and press Enter. If you see the words “SUP>” then your pi0 is ready. You can quit Terminex by pressing SYM+SHIFT+Q
To load a TZX, place some TZX files on your SD card and you should be able to select the files from the Browser and the Next should do the rest. If you come across a game that doesn’t work please let us know.
