Speccy is now on v4.8, but here is how to enable the Sam Coupe emulation in Speccy...
"The major Speccy-Android 3.0 release has hit the Google Play this morning:
https://play.google.com/store/apps/details?id=com.fms.speccy.deluxe (full version) https://play.google.com/store/apps/details?id=com.fms.speccy (free version)
In this version, I have added the initial Sam Coupe emulation. To enable it, go into Settings->Emulation and select "Sam Coupe" as computer model. All Coupe-specific display modes should work. The SAA1099 sound chip partially works, except for envelopes. If your device has physical keyboard, it will act as Coupe´s keyboard. Disk drives do not work yet, I am working on them.
I have also enabled Settings navigation with gamepad and added ability to reassign Moga controller buttons, something many Moga users asked for. Finally, I have fixed the battery drain that occurred when Speccy ran in the background.
