Yes but both emulators are supposed to follow most hi-res schemes ( the demo is WRX ) especially Eighty One, the file being available in P format would confirm that it is for emulator use also.
It also comes with a Windows based mini emulator ("cdx81") derived from the z81 emulator, which loads .wav files
I did successfully run the 1kB rezurrection code on cdx81. (Load "" starts the high speed loader, then F1 loads the first wav file)
I did not manage to get the 1kB version to run on either SZ81 or EightyOne, but perhaps others will have more luck?
For a quick 1K test on real hardware, I think Dr Beep's programs are easier to load
