I've tried out this virus with other viruses and it gives some different effects. danooct1 said that it changes the video font to random gibberish characters, making the computer practically unusable until it is restarted. In addition, it changes the video font to rotated characters, they are not corrupted, you can still read it. Rotate your head for 90 degrees and you'll see it's still readable. In addition, it adds an extra space for use if you need it.
The following viruses were ran with Radish Virus: Green Caterpillar, Abraxas, Burma, Apadana, Casino, Shatin, Alert, Suicide
Few notices: You'll see that Abraxas wrote some garbage text, Burma got 2 errors about Floppy A not being ready (I've used fail on 1st error, abort on 2nd, virus was terminated). These events happen even if a Radish virus is not running. Suicide virus won't disinfect itself...
Most of viruses doesn't fill the "extra" part made by Radish virus.
