It is now using my ARM Assembly Core so it runs fullspeed with (48K) sound at a battery friendly 66Mhz (some games run fine at 40Mhz!).
It supports both 48K and 128K spectrums with all op-codes supported including all undocumented ones.
See the read-me file for further info.
Thanks to Christophe Lennard for the icon.
