I've only tried this with MirageOS but it should work on Ion, CrunchyOS, and all the rest.

At the start of the program, type in: :"(what you want the OS's to display as the name).
This should have, due to the preceeding colon: ::"(OS name)
For example, type :"PUNK QUEST to have the OS's say "PUNK QUEST" wherever it displays the name(usually at the bottom.)
In the editor this will show up as ::"PUNK QUEST .
