Hi, i tried several games (Roms) and have the same problem.
i noticed this when i played Marvel vs Street Fighter, i thought i need to increase frame rate because the game a bit too slow, but when i increased to 3 fps the screen start to blinking, the more i increase frame rate, the more blinks it makes (until the screen totally black)... Ace Combat 2 works fine, need for speed works fine on frame rate 2 but starts blinking on frame rate 3...

Anyone have the solution?

Thank You

What you are talking about is frame-skipping, not frame rate. Frame skipping, the one you change from 0-9, is used to skip frames, as the name suggests, thus increasing the frame-rate. I'm not sure exactly how it works, whether it skips every 1-9th frame, or something else, but what I do know is that it doesn't work for every game, and for the games it does work, it works differently. If you get good results in CMR 02, with FS set to 2, then you probably won't get good results in Tekken 3, or many other games, using the same number of FS. Higher FS doesn't necessarily mean higher frame-rate and it many cases will cause the black-blinking screen you described.

ow okay, so basically i just keep looking and trying for the "perfect" game that suits my HTC HD Mini, right? but is there any additional method to solve this, such as increasing performance of my phone, or whatever?

Thanks, sorry if asked too much...
