v1.0.2

There's some variation in the timings of different Thumby screens. If the previous releases don't work, or are very flickery, one of these might be better.

These don't include the level data, but if you upload the single install release first, then one of these on top of it, the data should persist.

Single Install

This release packages everything up into a single installer.
Plug your Thumby in to USB, then switch it on while holding the 'down' button. This will make it pop up as a USB drive on your computer. Drag and drop thumby-doom.uf2 into this drive.
Everything on your Thumby will be deleted and replaced with Doom.

Thumby Doom v1.0.0

Installation is a two step process. Install doom_tiny.uf2 by putting the device in bootsel mode, then install the data using picotool.

picotool load -v -t bin doom1.whx -o 0x10040000.

This will delete everything on your device!
