Everyone keeps suggesting WHDLoad. WHDLoad is the answer. Avoid floppies with WHDLoad. But you need original disks to run WHDLoad.
I am not advocating piracy in the Amiga scene by suggesting that you should have a chestfull of Amiga games on "non-original" disks...but looking at how eBay auctions go for used Amigas - many come with a large sac of games / apps that are just on unmarked disks. And people sell sacs of these "blankable" Amiga disks by the hundred for $20 on eBay and I am sure many people get lots of Amiga apps this way.
I am just saying - it is probably not worth taking for granted that everyone who posts looking to setup a game system is looking to throw away the 100 disks that came with the used A500 they just grabbed and go out and try to find original games - so a qualifier to the WHDLoad suggesting might be wise to mention: that you need original disks (that is, un"broken" verrsions).
I just use my Amigas for demos - so I get to avoid even such temptation into the dark realms that I discuss here!
