I have had a look at the code in the V 1.3 rom.
The error #4 is displayed when slot slow down doesn't work correctly.
It sets the speed to 1MHz and measures the number of loops between two
VBL
Then it sets the speed to Fast and accesses slot 6 port C0E0 (I guess
it is expecting CPU to slow down) and repeats the follow 30 times,
measures loops during VBL again and compares it to the orginal value
measured.
If you check your speed setting on slot 6 you may find it set to fast?
