The palettes are different for each game...but i imagine you can just do a search on google for snes pictures, then grab on of them and save the palette in Psp/ps,and load it when creating a new pic
SNES ran at 320x240 resolution with 256 colors. As long as you keep to those limits, and only use 16 colors or so in your sprites, it will look pretty authentic. Of course, you can also do things like look at some old games and copy their interfaces for an even more convincing appearance.
If you wanted to really go for the authentic look, and you're planning on having a lot of objects, you could have a counter that keeps track of how many active objects there are, and then randomly flicker them if you exceed 128 on the screen. It might be annoying, but at least it would be authentic. The SNES could display a max of 128 sprites, with 32 per line. If you do this, make sure you can disable it, as some people would find it more irritating than nostalgic.
There is a 'flash' action you can do. This flashes the object visible/invisible at an interval you decide. To stop it flashing, set it to 'visible' again.
theres alot of good advise for making authentic SNES games here.
what do I need to save the picture file as to be able to load it as a palette?
my main problem in recreating the SNES graphics is I tend to use too many different colours, so if i can just load a palette with the exact amount of colours, it should make my job easier.
anyway, im gonna get back to "studying" my old SNES games (using an emulater, ofcourse).
