+Even though ZX-81 ported my Wiz version to Caanoo, some people kept
+asking me to do the port instead because of apparent sound problems,
+so here it is. Note that I did not use ZX-81's work for this release,

+possible. Savestates might also be incompatible.

+I've appended the original gpSP GP2X readme file as it contains lots
+of information that is still relevant for this version, as well as
+development history of this project.
