We'll look out for those.

It might not feel like it but with the restoration of the video RAM and video chain you've taken another major step forward today. If these next measurements don't point to any specific area we'll try the memory bank swap / memory halving tricks to see if they show anything useful. They might, might not.

We'll also work out a way to get Slothie's test code into the machine to test the system RAM in-situ, if possible.
