is there any way to run european nes games perfectly on the retroduo

[andreasaspenberg]

i got a retroduo console recently.(super nintendo with a nintendo slot.) a problem i encountered is that it runs the nintendo games as if they were american. that cause a lot of glitches in my european megaman games.(invisible wall in megaman 3, metal blade stuck in mid air in megaman 2 and too fast music in all of them.) what i am wondering is if there is a way to change that in order to make it run them as they are.

Use an emulator, saves you time and effort.

Depends on the internal circuitry. It might be as simple as changing the oscillator circuit to run at 50 Hz to as complex as needing to reprogram the firmware.
