When I got my A1200, EdPlayer was preinstalled on in for demonstration purposes. It plays Protracker Mods and 4-voice MED files. That's it. It has a nicer look since it opens up on its own screen using a split-screen effect.
After a while I started using custom copper lists to make my 3 bitplane Workbench screen more colorful. This ruined the EdPlayer palette advantage. To make matters worse, I started playing with other formats than what EdPlayer supported.
Now I use HippoPlayer and am happy with it. HiP FTW!
