I’ve tested again in winUAE and on real hardware and haven’t encountered an issue. However to be sure I have re-exported the ADF and updated the file on the page. Hopefully it will work properly this time!
Ok that sent me down a bit of a rabbit hole but there was a memory problem on certain configurations. Had to do some jiggery pokery - specifically to level 1 - but all seems to be working now! Thanks and apologies!
