The game code has some data embedded in it for processing strings such as "COINS IN", or "ROYAL FLUSH". Using the offsets I discovered in the graphics files, I was able to come up with a chart of letters that correspond to data found in the game. With this information I then added comments to the source code wherever I found a string being used.
The more strings I find, the more the code starts to document itself. I am finding the same subroutines being called after loading the strings, which makes me think its routines for painting to the screen. Time to dig around in the code.
