The POKéMON PC storage system made by Lanette has been updated by her older sister Brigette and is now available for all trainers to use!
There are 25 boxes to use and each can hold 60 POKéMON or POKéMON eggs. Like Lanette's PC system you can change the wallpaper, mark your POKéMON, check their summarys, and more easily arrange them.
Once you upload them to Box and quit you're able to switch game paks and start Box back up. From there you can send them down to the other game! Makes for an easier and faster method of trading!
A new thing is the option to view a list of them similar to the kind introduced in POKéMON Stadium. You can have them listed by alphabetical order, POKéDEX number, species, etc. Their stats are easily viewable as are their natures, abilities, amount of ribbons, all that good stuff. It's also a good way to check how many POKéMON you have in total!
By the way don't think you'll have to move each and every PKMN one by one to and from Box. By holding in the A button and dragging the cursor along you can easily select anywhere from 2 to all of the POKéMON in a box. Then release the A button and all of the ones you highlighted will be moved to wherever you want in one shot.
The new options and ease of use make this a pleasurable update to the R/S PC system.
But in order to access this in Ruby, Sapphire, Fire Red, or Leaf Green, you'll need to have registered at least 100 POKéMON in your POKéDEX. Also, until you get the National POKéDEX in Fire Red & Leaf Green, you cannot transfer any POKéMON besides the original 151 from Box to those versions.
