I've seen a lot of requests for Ultimate Bet mods. I finally got around to doing this for myself and thought I'd post the steps.
UB graphics are stored in resource dlls. There are a bunch in the UB directory. The tables are in resSplash.dll but there are others.
This is how you mod a table:
1. download PE Explorer
http://www.heaventools.com/
2. open resSplash.dll (make a backup first!)
3. select View/Resources from the menu
4. find a table under IMAGE
5. right-click on the image and Copy
6. paste the image into an image editor (Photoshop, Jasc Paint Shop Pro...)
7. edit. The easiest edit is to take the table with black background and fill the background with another color. For my own edits, I've taken the ub logo off the table using the clone tool in PSP.
8. copy your image to the clipboard
9. back in PE Explorer, double-click on the table number under IMAGE
10. paste your image into the Replacement source. Click OK. Save your results.
If you want to get fancy and complete, when you change the tabletop, you need to edit the folded card bitmaps because they contain parts of the table. They are in res2D.dll.
Good luck.
