Rock'N Roll Your Own (Windows/Classic Mac, Medior, 1995)
You can download it as RNRYO.toast_.sit here or here, and run it on modern systems by following the instructions below the images.
Open this in-browser emulator.
Drag the file you downloaded onto the emulated desktop.
Open The Outside World, then Downloads, and open the file you'll find there. Wait while its contents are extracted. Ignore the error message that may appear. If nothing new appears afterwards, close and re-open Downloads.
Drag the .toast file that will have appeared into Uploads in The Outside World. Wait for your browser to suddenly download it all at once as a .zip file.
Close the emulator's tab or window and open this other in-browser emulator.
Extract the .toast file from the .zip file and drag it onto the emulated desktop.
Open the icon if it doesn't open automatically, and run the program. If it wants installing, install it into Infinite HD, not Macintosh HD.
