Has anybody actually tried to write program code for the PAL TG16? I've said before I don't believe any exists. It'd be nice to at least have a tech demo of how real 50hz games would've performed.
They would perform the same as a 60hz game.
If it was written FOR PAL, it's reasonable to assume the developers would have tweaked the game during playtesting to play well.
So, it's kind of a moot point.
For example, lets say I wrote Atlantean for PAL. The end result would be the same.
The songs were written externally, so naturally, you would tweak the tempo so it sounds right (Similar to how if you play a PCE game on a PAL system, the songs are slower. I would adjust the tempo to compensate and fix this).
Then, the gameplay itself would have gone through the same playtesting and tweaking until it feels right.
Under the covers, the numbers would be different. Other than that, it'd play the same.
If you're curious how actual, commercially released PAL games play, go look at European C64/MSX games. Those were generally all written for PAL.
Oh, I could be mistaken because I hate the game, but Turrican on Turbo Grafx might be running too fast since it's a PAL game.
Compare it to the Amiga one and see, I guess.
At a quick glance, the tunes seem to be going too fast on Turbo Grafx.
So, Turrican TG16 might play less shittily on a PAL system.
It will still suck because it's Turrican though.
