Hey good on ya mate! That's great too we now have potentially two textures for the Dido types.
You take the deck textures from the GENxxxx files within the model. Use the Hex editor to FIND the files labeled GenBritish or GenUSA etc. These give the deck and flag textures. These are external files (of course) and you don't need to extract them with COVET's tools.
Do let me know which ones you plan to cover or are covering (no harm in doubling up though) so we can cover more ground in less time.
Right now I'll be working on Bruno's TA types so have a go at the Brit cruisers
Cheers,
Mountbatten
