Step1
Name your GIF “bdXXX.gif” where XXX is the name of your board.
Step 2
Put your GIF into a Zip file named “bdXXX.zip”
Note the name must be identical.
Step 3
Create a text file with one line of text “Version 1.0”
Step 4
Delete the .txt file extension from the text file
Step 5
Add the text file without an extension into the bdXXX.zip file
Step 6
Delete the .zip extension from the zip file
You now have a usable Vasl board.
However this assumes that the original GIF image has been scaled correctly to fit the Vasl hex grid and the A1 hex is in the correct position otherwise there is more preparation needed.
