I am not sure about whether to use "match manual" or "match manually". I am not native but I know that the latter is grammatically correct as the word "manual" has to be used as an adverb in this case. However, "match manual" still sounds very correct to me. Is this a special case?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
It is correct to say like manual collection, manual transmission etc , but it is not correct to say like match manual. This is because collection, transmission etc are nouns, but 'match' is a verb, so it is perfect to say like match manually. i.e, with noun you should use 'manual' and with verb you should use 'manually'.
