That was kind of my point, the display capabilities have -NOTHING- to do with the processor or system, or the number of 'bits' a system has. PC may be 32bits or 64bits, but remmeber you can still run your desktop in 4color or 16color or 256color (8bit per pixel), 16bit (65,000 colors), 24bit or 32bi...

It just relies on having both a 'material color' and an alpha blended texture. The texture is of the explosion with an alpha mask, and then you can just make the textured quad get bigger over the course of 250ms or so, while also reducing the alpha of the material color. (So that the material color ...

You're going about it all the wrong way. Instead of manually getting each pixel, manipulating its values, and setting it back, which would be HORRENDOUSLY slow, do this: Make a quad, color it red, give it an alpha channel of like 40% or whatever, and draw it over your entire screen after your done d...

initials[3] = '\000'; ??? Why three 0's?? You only need: '\0' or, better yet, just do: initials[3] = 0; to answer some other questions from above, there are times when you need to take 0-25 (or 1-26) as a letter in the alphabet, and the easiest way to do that is: char mychar = 'A' + num; or (num-1)....

You arnt able to burn a CD or a DVD of the files... The files have to be generated using an internal tool that packages the files into the correct format that the testkit or devkit can use. As previously stated, sending them a memstick isnt advisable because unless they have a 1.0 or 1.5 retail PSP ...

The issue here is that if you're planning on making a loader that runs games from UMD, those games will never return. So both programs will be loaded and running at the same time after you start it. If you're displaying an image, you cant afford to 'steal' that memory from the game you're trying to ...

47 fps? If you are on platform you cant get any other FPS values than 60, 30, 20, 15, 12,10, and then you get some strange ones. It has a 60Hz refresh rate and everyone should be using vsynch, so only fps values that are 60/x (x = int) can work. Anyways, FPS is not a very good way of testing code sp...

I cant download the file to see exactly how you're doing this, but a bigger program should not be slower. Depending on what you're doing cache misses can be an issue, but honestly I think you're probably just going slower because of multithreading. If you want to run a test, Id suggest loading up th...

sceDisplayWaitVBlankStart() waits until the VSynch gets called to the OS. Its tied into the screen refresh rate, the PSP refreshes 60 times a second. So calling it 6 times in a tight loop essentially is the same thing as doing a sceKernelDelayThread( 6 * (1000000/60) ); which should be 100 milliseco...

One cycle isnt enough. The typical way to do key holding is to set a timer when you press the key down, and once that timer reaches some value (400ms or so) you signal the output again, and then set the timer back to something like 300ms, so that the next signal only takes 100ms... This is how you g...
