After playing a while I noticed that because of PAL it's slower than the PC version - and it's much much easier because of this! So I switched the C64 to NTSC and it feels a lot more challenging like the PC version! But sounds are also much faster in NTSC mode, would be nice if the sounds can be the same speed as in PAL. Maybe there should be a witch PAL/NTSC in the options...

It's strange that you say the game is slower on the PAL C64 version (and therefore easier?) than the PC version. I remember well that when I programmed the PC version, I calculated all the timings based exactly on the PAL C64 version. In fact, I used a stopwatch to time how long it took me to complete the first level, both on the PC and PAL C64 versions, and the time is practically the same. I should add that I won't provide any option to "align" the game and sounds speeds between PAL and NTSC, so everything is exactly like the original game.
Must be something in the Emulator I tried with. This afternoon I installed H.E.R.O. Is Back in my MiSTer and now speed is the same as the PC version. Weird.
I also tried the original H.E.R.O. In NTSC mode on MiSTer and the sounds are faster there, too. It looks like there was never a NTSC/PAL fix for that game. Maybe it would be nice for all NTSC users to have the same experience…
