[Other] Temporarily replace party Pokemon

[rortik]

There is a point in my ROMhack where I need to temporarily replace the party Pokemon with a specific team, then later change it back.

I've tried to copy this kind of script off other roms where this happens (Battle Factory in Emerald, etc) but with no luck. I know I've seen it done before, I just can't figure out how to do it.

How can I do this?

If you're hacking FireRed, you can use a bit of ASM that FBI wrote to temporarily swap the party.

First you'll need his custom Pokemon storage system:

Then you can swap the party by following this:
