there are many reasons for this, but I can only comment that they should have left GIS alone, and not let ACS divest. They'd have been stronger this decade with those performing assets.
It seems the affected update file seems to have been over written with 0s on the 42kb file, whereas the before and after sys files have obfuscated ays/config file info as expected.
They all use the same hardware in the joysticks and have been for years (maybe since 90s). there must have been a defective version made along the way, but it's not an easy nor cost effective repair.
so yeah, thanks Carl.
