+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,
+because I had various changes for Pandora version and wanted to have
+them in, so different set of bugs then in ZX-81's version are
+possible. Savestates might also be incompatible.
+
+To use this, you'll first need to copy authentic GBA BIOS to gpSP
+directory. It must be named gba_bios.bin and should be 16kB in size.
+
+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.
