Ahoy @gap
Your question as to whether the modes available here are compatible for your SH2 and DC depends on the language and country of purchase.
As far as I can remember, sometimes the file managers - depending on language and nation - had a slightly differentiated structure within the game folder.
Therefore, for example, such outstanding big-modes as "Frontflottille" and "Zerstörerflottille" of the 9teUflottille work only with the German versions of SH2/DC.
I'll check tomorrow what I find on modifications on an old record - with a nice sound mod for DC I can serve anyway.
