I would go ahead and swap the 245 on the lower pcb just so you can rule it out.
I dont think slot 4 is passing the check since you are getting the crosshatch instead of it loading the game. The graphics used to render the memory viewer comes from the S1 rom on the active slot. If the board isnt able to get at the S1 rom for whatever reason is common you will get a mostly blank screen, since the char data is all 0xff.
A. That would be true if you disconnected the input pin on the 245 coming from the slot board. If you disconnect the pin on the cpu side, it will normally take on the last state the data line was in (from being used to read other parts of memory)
B. Cant you just do the probing with it powered normally?
