Is there an application that can convert ntsc roms to pal version.
I find that it is better to play PAL version since you are running fullspeed of the game at 50fps. I can play donkey kong & mario kart fullspeed at 1 frameskip (50fps). If you are playing an NTSC rom at 50fps it is slow unlike in PAL it is at 100% of the speed.
But there lots of games that i like that doesn't PAL version. Is there an application/program that can convert? i've been searching for months now and I can't still find any.
I found something that can convert ps2 games so i was hoping that there is something for Snes roms. If you know some pls tell me

AFAIK the PS2 games mostly work out based on separate counters, independent on the frame rate pretty much. On old consoles like SNES though, games depended on the VSync rate (or counters that are relative to it) to count time.
Snex9xTYL has an option of something to do with PALN and NTSC though.

Not really. Try playing the same game between PAL and NTSC. ie. Mario kart. If you play a PAL mario kart running at 60fps the timing is incorrect. The game is played much faster. Now try Playing NTSC @ 50fps You'll notice is it slow. So playing PAL version of the game is advantage since you are playing 100% speed of the game at 50fps. It is like 20% speed increase from NTSC because you need 60fps to play 100% speed. If you have experimented enough you'll be amazed how much difference that 10fps makes.
I really hope there is a converter.

I know, that's not what I meant. I wanted to say exactly that: the game is hard-coded to run at a certain refresh rate. For example, if Mario should run 100 pixels per second, the code will move him 100/50 pixels in PAL and 100/60 pixels in NTSC.
That's why I don't think a general-purpose "converter" can work.

ahhhhh now i got it. Thanks for the explanation. I was kinda hoping there is one. Its disappointing  I've fiddled with some sega genesis games. I was amazed that they have roms thats is compatible with both PAL & NTSC. for instance "Sonic the Hedgehog (JUE) [!].zip" If i set the emulator to play as PAL it would play @ 50fps 100% speed and if set the emulator as NTSC it will play @ 60fps at 100% speed. It would be nice if SNES games where developed like this  |

that's more to do with the emulator eugene than the game I recon.. as in, it skips frames so it plays at 50hz or whatnot.. (I would think)
Unless there it's the same thing with the slow n fast stuff

manias - The Emulator sets the fps to 50 if it is PAL because the game is made to run at 50fps. The games timing is messed up if you manually set it to 60fps. That goes for the NTSC version too. Not all games for the genesis is both compatible with PAL and NTSC. like this one "Sonic Spinball (E) [!].zip" if you played it at 60fps it is faster than it should. So It has something to do with the the game itself not the emulator. Just like what Tinnus said from the post above. This is the reason why I'm using PAL version of games on emus for PSP (if the PAL version is available). Sadly most of the games i play doesn't have PAL version. Tinnus - Do you think its possible to create a converter? I'm not a programmer/coder. I just wanted to know if its possible.

you made it sound like in your previous post on a genesis emu that if you set the emulator to NTSC that exact game runs at 60fps at fullspeed, and @ PAL at 50fps at fullspeed! And now you're saying that the timing IS messed up.. LOL
Your first comments sounded like an emulator thing, but since that's not like you said, ofcourse it's game related. Hard coded for 50fps so that's what it wants to be at.
Anyway, this is only relevant for slow games. Most games are at fullspeed so you won't have to bother.

I don't think this is possible for nes/snes games, because as tinnus stated the games are hard coded to support the PAL/NTSC protocols. Thus the ways the games do it are unique for each game so no general application can be made to convert it, and i don't think (i could be wrong) this can be fixed by changing the emulator engine.
