so i got the powerpak recently and been playing tgl along with tgl secret thats been done so far. so fater a few camera captures of some passwords i decided to play the euro version of the game on my nstc nes and i have to say the slight speed up and the pitch shift that appears to be present on the actual system is quite cool. all i can say is i don't think you can do this on an emu cuz the emulator auto corrects this difference
In emulator when u switch between PAL and NSTC it affects speed. U can use auto or choose by urself. Also usually there is speed options in emulators too.
