Nice tool, what devices does it recognise ? On my TR ST it has some question marks for slot 0-3 page 1, slot 3-1 page 2, slot 3-3 page 0,1,2.
It looks like it doesn't detect SCC+ or SCC cartridges, my Memory Mapper in the extender isn't found and the music module in the extender has 2 question marks at slot 2-0 page 1,2. From the sunrise CF ATA-IDE it does detect the dos2 rom.
