I could try to convert that whittaker's music into some low-rastertime tracker (ninja tracker or so), but I also care a lot about time and enthusiasm. Otherwise, of course, the music is almost the same as at ZX Spectrum AY, but I really like it :)
Pls keep original Whittaker music, maybe to make a choice! Adding an animated intro from the ZX Spectrum 128 version is also not a bad idea. Otherwise, thank you for superb work, this looks really great!
