Err... should have qualified that, might have been seen as impolite :oops:
I wasn't sure if it was a hardware problem, that it was 2.17c made sense.

I've had a look and the associated MDV routines in 1.36 and 2.17 are identical. The RAM driver code is completely different, 2.17 looks like an early version of SMSQ/E level 2 RAM driver. Need to delve deeper into inner workings of 2.17 RAM driver.

Here's a fixed version of Trump card V2 ROM with working FORMAT RAMn_MDVn.

I've only tested it on my Trump card V1 hardware but it should be OK since the problem was with routine converting the MDV sector dump to RAM driver filing format (level 2).
