does the m30 support xinput?
you can use xinput plus to remap it if that is the case.
you can map the buttons however you like in most indies.
i used pic related (with the dongle connected to an adapter to get it recognized as an xbox controller) to play momodora moonlit farewell and shantae 7 sirens.
i try to use it or the 8bitdo neogeo controller whenever i play 2d platformers on pc. changing the mappings is a one time deal, so it isn't a pain.
