So you buy a game called Earthquake and then complain it looks beat up.... do you not see the Irony in that
Ok enough
humor for now.
Glass + Strips + 2 chips makes up your game kit.
The chips are a Reel Chip - which is the theme, and the Game Chip which controls the function of the machine (ie hopper limits, reel sounds, etc).
Reel Chips have a "type" - Type 0 is no features, so if you go from Cats and Dogs to Black Tie both are Type 0 games and you don't have to change the Game Chip.
If you check out Ricks Faqs - home page bottom right, he walks you through a game change.
In Rick's ....You will also find the IGT game bible there that has a listing of all the different themes for the S+ and which chips are necessary for each.
If you change the game you will need to reactivate the Bill Validator so you should get a SET chip, and while your at it get a Clear chip.
The cost of shipping will be more than the cost of the chips so get both.
The clear chip is not often needed but it takes the machine back to factory settings and if you change the battery on the MPU board you can sometimes get into a funny setup loop after the battery change and the only way to resolve that is to use the Clear Chip.
Again I will refer you to Ricks for the detailed instructions but basically you remove the Game Chip, pop in the Set Chip, set the denomination for the Validator, and then pop in the game chip again.
Clear basically works the same way, except it will leave the Bill Validator disabled, and you then run the Set to enable it.
If you change denominations ie 25c machine to a Penny machine or a dollar machine. Then you need to possibly change some of the coin handling.
You may note that the IGT glass is all stated in Coins so its not like you will buy a theme and then say %^&*( I need to change denominations - its more likely that you have already bought 3 quarter machines and your latest deal is a dollar machine and you want them to be all the same. In my case I run quarter sized tokens in mine and they all need to be the same.
For coin handling changes, the Coin head (shiny metal thing on the outside where you put your coin in) changes in width between, Penny, quarter, dollar. Some have an imbedded currency stamp like $.05 embossed others are just silverish. The coin comparitor has to have the right sample coin. The CC-16 is for small coins and the CC-33 is for larger like $1 and big tokens. The coin optics below the coin comparitor has spacers as a nickle and dollar are wider than a quarter or a penny and of course a dime is thinner. Dime machines are not common. Finally the hopper wheel gets changed out to match the coin size, and depending on the hopper the hopper optics need to be set higher for large tokens.
Some warm water and vinegar does wonders for the look and smell of the glass, and the same with a sponge on the reel strips.
I typically use a liberal amount of Oven Cleaner on the interior metal of the machine along with an abrasive kitchen sponge to cut through the casino funk.
