I've now insured that all of my items include a Mac-Compatible download alongside the PC-Compatible download. I also include a "Mac Engine" to allow proper running of the included SWF files.

That depends. My software usually requires shifted punctuation for the buzzers (Shift + 1 thru 8 on a US Standard Keyboard: !, @, #, $, %, ^, &, *). If the buzzers do generate those keystrokes, then you've got a set compatible for my items. Unfortunately, if you have buzzers from Affordable Buzzers, it looks like they only generate numbers, so they will not work with my games.

AFFORDABLE BUZZERS UPDATE: I've been informed by a customer that reprogramming of the Affordable Buzzers equipment is possible. However, I want to test that in-house myself before I recommend them. Once that happens, I'll post it here and as a shop announcement!

There are several shops here on Etsy that can create custom USB buttons that can generate the necessary keystrokes. Here are their links:

My YouTube Channel is up and running, but minimal. I will occasionally do Livestream Tutorials for my software, which will stay on the channel to review later. As for "How To" instructions, send me a message with your game requests, and I can send you the Operations Manual PDF free of charge.

All of my software allows you to create custom game and question material, with some including separate "Builder" programs to help create the code to make it look good. However, if you need customization that goes beyond that (think logos, sound effects, et al), please send me a message and I will send you a quote. Any change to the software has the same base cost, no matter how minor the adjustment.

Most of the software in my shop are "Game Controls". What does this mean? Basically, it means they aren't video games. These are designed for someone to use for playing with other people at game nights, events, etc.

Also, most of the programs are "Two-Screen Experiences". They each have the Game Display program and a User Control Panel program. To get the optimal use from the programs, you will need to connect your computer to a second display (Monitor, TV, projector, etc.) to use both programs simultaneously.

I also include a fully-detailed Operations Manual with each game so anyone can run any game with little to no assistance. If help is needed, my email (gameshowmachine@gmail.com) is always open.
