Do not use "Hero Quest (USA) (Proto).nes" as it is an early (and more unfinished) prototype that is already NTSC. 

The later PAL prototype is much more complete, so I replaced the section of PAL ROM containing PALHERO.MUS with NTSCHERO.MUS from the source code. 

Same number of bytes, it just worked.

After patching, remove "(Europe)" from the file name so emulators won't think it's still PAL (FCEUX).
