Snapload V3.2
Posted on November 14th, 2018Added a little feature to the NMI menu of the SMART Card’s snapload ROM: When a .tap file has been loaded, the current position of the (virtual) tape can be stored and restored allowing “rewinding” for multi-load games (the tape now also automatically rewinds at the end). The latest ROMs are – as always – available at www.retroleum.co.uk/smart.zip
