hehe, Lord Orwell... I had something similar a while ago.
I had a game on the Amiga called R3, I thought I'd recreate the game on the PC.

The problem was that all graphics were stored in .iff files with the header&palette missing! It took me quite a while to read the images and add headers,palette and save them out as .bmp files. But it was great fun.
