I have noticed when importing a WHDLOAD games set under the Commodore Amiga platform, the vast majority of games import with the correct game title (without version numbers, etc).
However, some titles don't rename to the title found on the Games Database and instead keep the trailing version numbers and extra info.
When checking a test import it seems the games affected are those which have muliple versions merged under one title.
If I untick "Combine ROMs with matching titles into a single game", the games import correctly (although as seperate entries for each version, but the title is correct). Manually merging after this import seems to work however would be very time consuming.
