I found this thread by accident on the TIZ forums and though that some users here would find this interesting. It's a pretty cool tool by MarvelousMirth, but it's still very early in development (I personally couldn't get 720p to work in the games I tried so far).

Out of about 10 games I've tried so far, I've only had some success with one, which was the demo of Lamborghini. I can't test any more, as I only have the stock 10gb hard drive, and need to get a larger one, which is why I'm making the tool public now, so hopefully some of you can try it out, and let me know if you get any positive results.

I don't quite see the appeal of this, none of the games seem to run right after they are patched from the Images hes posting. The menus are all still super small and theres a odd Box in the top left side of the screen where im guessing the original resolution would have stopped at. If it enlarged the complete game to 720p I'd be interested, it just makes the game look broken to me. But maybe Im just misunderstanding..
How many games render internally at 720p? I guess none of them. There is no point to have such application. I'd rather like to see a 240p hack. FOr years and years noone has been able to do such thing, though you have dozns of people building retro-gaming Xboxes full of NES and Amiga games but running all of that in totally wrong video modes! Of course, if using crappy LCD noone cares, the video is shitty anyway, but how about the real deal of 15 kHz CRT TV? Well, no chance my dear Xbox. Microsoft did not bother, noone else either. Groovy or Advance MAME is your only option. Sad story I know.
