Hi I will give it a go and will pop you a few GBP if it works. I think that the issue is with new games, which don't have an entry in the WHDbooter xml file. When the mini can't find the entry the game fails to load even if there is nothing wrong with it. Some recent games like Maria Renards Revenge and the Turrican 2 AGA remake had the extra bits to add to the xml file on the itch.io page. ADF files don't have this issue, they usually just work.
