Because ".code" is the actual file name within the exefs; ".bin" is an arbitrary binary designation.
If you're getting "code.bin" your unpacking method is doing it wrong.
pk3DS has a built in pack/unpack functionality for exefs binaries...
For MiscTool:
The top area will unpack to a folder in the same origin directory.
The middle area will repack a folder given the input type.
The unused button doesn't have anything programmed. It needs DARC Repacking (done), ETC texture (de)compression (not done) and a UI (not done). I still don't know if I want to do that as I'd figure scripts and a DARC repacking utility is much more doable.
Wallpapers is a placeholder button; even if it were enabled there's no form to show.
MiscTool is a bit more debug-oriented; it can unpack garcs(garctool)/darc/mini, can view bclims (non etc), and can repack DARCs/mini.
They get 3 random starters by coming up with random numbers then swapping the models and tweaking text. They're then changed back.
Starters cannot be randomized at this time.
model swaps, he did not randomize the starters (someone else likely came up with 3 random starters and swapped data accordingly)
the 'shiny' latias was a model swap and quick-cut too.
You need System.Web.dll, which you should have if your .NET is up to date.
If not, you can always manually download the dll and put it in the same folder as PKHeX.
Nobody bothers to read the About window...

Control-Alt-Click a slot to (Clone/Delete) set a Pokemon to every slot in the box.
Control-Click a slot to load slot to tabs.
Shift-Click a slot to set tabs to slot.
Alt-Click a slot to delete the data in slot.
the version after the dash needs to be 20 or greater; the system modules (browser) that you have does not contain the same browser version that is exploited.
Music played is based off of the trainer class.
It's likely set in one of the dll's which are uneditable (because Gateway does not disable .CRO0 checks).
The first four hex digits are the Pokémon's checksum. If the EC and Checksum are the same, the Pokémon is quite likely the same.
I'll switch it to an actual hash in the next release, as some sets may result in the same checksum.
