In my last post we left of having successfully decoded the PAK and EGA image formats used by Electronic Arts with 688 Attack Sub. In this post we will reverse the process allowing us to convert an input image into the format. This post will mostly concentrate on the EGA image format, as there really isn’t anything to do with the PAK image format as it was just raw image data. The EGA format is more interesting in that it uses a form of RLE compression we had not seen until this point with the formats we’ve looked at so far.

Attack of the subs
A little diversion while I wait for parts to arrive for my RAID data recovery and rebuild. Fingers crossed we don’t end up in a whole series of reverse engineering the Drobo BeyondRaid Filesystem format. (Though that could be fun for sport, AFTER I’m back up and running) Today’s target comes as another request. This time it’s 688 Attack Sub from Electronic Arts. Looks like there are a couple of different image asset files, PAK (and an accompanying PAL file), and EGA. So let’s dig in and see how far we get.
