A lot of the in-game pictures like Photo Hunt are jpeg's. Just replace the files

There is a video on YouTube showing how to do this:

How were you able to achieve the animation on the background?  I know this is Ion and not Force, but it looks like the force animations are in a proprietary format.  There's a tool that has a symlink to it on my 10.5 machine called sprcompress, but it's not actually on disk (it should be in /Software/usr/local/bin which does not exist on disk.).

Any info or suggestions would be appreciated!

The same Sprite format is used in both Force and ion. I have code to convert back and forth between Sprite and tga.

I wouldn’t even know what to have you convert to be honest. I’d want to decode existing SPR files and see how they are structured (individual images? Sprite sheets? Etc). Would be interesting to skin the existing games/menus.

It’s more of a raw morbid curiosity to see how they did their sprite packing, etc.  considering I’m sure my method is wholly inefficient: http://forum.arcadecontrols.com/index.php/topic,156300.0.html

The animations are individual images all in the same file. The Sprite format is pretty basic. Don't remember the exact format from the top of my head but there is a series of bytes that contains the color info in RGB, a byte that sets transparency, followed by the number of pixels to repeat.
