I'm glad you got it to work,
As for the rules, it's pretty complex. Pachislot has its own lingo, just like video games, so it's quite difficult to understand if you don't know a lick about Pachislots. A couple on months back, I tried figuring it out by looking at the instruction booklet and watching some videos, and I succeeded for the most part. I wrote a pretty extensive wiki article about it, and I should be correct about the general rules of the game. I also figured out all the menu options. So If you got any questions, feel free to ask.
