Most cheap IR toy remotes use a simple pattern of pulsed light at 38 kHz. Typically, each button turns the LED on and off at a slightly different square wave pattern around 10 Hz. More sophisticated remotes use a Morse code-like pattern to differentiate different functions.

So if you have an Arduino and an IR-LED, set it to strobe continuously at 38 kHz, then pulse it on and off around 5 times per second, steadily increasing that by 100thof a second. At some point you're likely to find a pulse rate that will activate one of the functions on the Disk Shot. Rinse and repeat.
