Hi, and thanks for a great initiative!

I tried to install and run the SWIFT, but it crashed with a "access violation at address 00541FAD in module Swift.exe. Read of address 00000010" when trying to open the Beeb-Invaders.swfprj

I was doing like this:
- download and install all neccesarry software:
- swift 4.2.4
- python-3.1.2.msi
- BeebEm412.zip
and the project SparseInvaders_Source.zip from the website.

When trying to open this project SWIFT crashes with the error mentioned above.
The excact same error appears if I go to Environment / Assemblers and click "Apply" after this first crash. (This works if it hasen't crashed yet.)
EDIT: Can this be caused by the invaders-project being made in an older version?

[EDIT:solved: In this config box I can't find the p65.py refered in the tutorial either, it's no such file in the Ophis-1.0-win32-installer.exe
I solved this by entering the full path to ophis.exe in Executable location, and nothing in Script file location]

Firstly , really sorry for not replying, just not been on the forums for a while. The video's are for much older versions. I need to redo them. Glada you sorted it
