I have an odd question that I hope I can explain correctly. If it's correct, then that'd be cool. Suppose I want to RNG an egg on Emerald, so that it is shiny on my FireRed cartridge. For that to work, I would need to search for a shiny egg frame that is possible with the TID/SID combo from FireRed. Once I find one, I would hit my frame on Emerald and trade the egg to FireRed and hatch it there. It would then be shiny. Is this all correct?
