HeHe... the only disconnect with WHDLoad is that it's still the best kept Amiga secret on the planet! I couldn't figure out what the heck it was all about and didn't really try for years. Once I figured out the real potential of WHDLoad, I bought an A1200 the same day just to have an AGA WHDLoad machine, That was in 2010! I'm convinced that a whole lot more people would be buying Amiga machines if there was a big 'ole button to click, prominately displayed on this site, explaining WHDLoad in simple terms and what it's capabilities are.
To accomplish what your asking for, you need 3 things.
1. The WHDLoad program itself here...
http://whdload.de/whdload/WHDLoad_usr.lha2. Legal ROM files...you can either create these yourself from your real Amiga machines or you can download and pay for them here...
http://www.amigaforever.com/3. Some game files.... I won't directly point to the files but, everything you need is right here....
http://www.lemonamiga.com/There are alternatives, Google is your friend.
Follow the WHDLoad guide to install your ROM files. Create a folder on your A1200 HDD named WHDLoad games. Create subfolders named A B C etc.... and place game files corresponding alphabetically in appropriate subfolders. You really don't need iGame or any other launcher.
As far as unzipping files with a GUI, these two programs work great on my A1200....
