Thanks are also due to Mark Woodmass for his excellent SpecEmu ZX Spectrum emulator for Windows. I have made extensive use of the debugger in SpecEmu while reverse-engineering the above music engines, and while debugging Beepola. And thanks also to the FUSE (Free Unix Spectrum Emulator) team for their open source, multiplatform spectrum emulator, which I also use for testing and debugging.
Beepola is written and maintained by Chris Cowley.
