Hi, I'm working on modding my first Pachislo machine, I'm a graphic designer by trade so I have the means to create custom reel artwork, but I don't know how to properly remove and reattach new artwork. Is there certain positions I need to pay attention to? I'm sure this topic has come up but I haven't found it in searches or on youtube.

I also saw a youtube video about custom sounds added to the machines. Is there an easy way to go about this or does it require new electronics?

Thanks in advance for your help!
