From GameBrew - a wiki dedicated to Video Game Homebrew.
PHBankManager (not affiliated with PHBank and its creator) allows the user to have multiple bank files that are able to be renamed with a computer or 3ds homebrew, and used offline in both .3dsx and .cia format.
PHBankManager currently supports up to 20 bank files. (30 Pokemon in 100 boxes for 20 bank files = 60,000 total Pokemon slots.)
If you have already used PHBank, then your bank will automatically be used with PHBankManager and other bank files you create.
If you have never used PHBank, then PHBankManager will create a new bank file for you on startup.
People needing more than 20 bank files can easily implement this adjustment, however an obscene number of, say, 10,000 bank files will need more adjustments made, but it is still doable. (Not that anyone will need to go this high.)
PHBankManager 3dsx Prerequisites: Grab the latest PHBank.3dsx from https://github.com/gocario/PHBank/releases Merge the "3ds" folder from the zip with the one on the root of your SD card. Grab the latest pkbrew from https://github.com/gocario/pkbrew/ Copy the "pk" folder from the zip onto the root of your SD card.
Installing 3dsx: Unzip the PHBankManager zip file. Merge the "3ds" folder in the zip with the "3ds" folder on the root of your SD card. Copy the "bankManager" folder from the zip to the SD root. Launch your homebrew loader, and run "PHBankManager".
PHBankManager CIA Prerequisites: Grab the latest PHBank.cia from https://github.com/gocario/PHBank/releases Install the "cia" file from the zip. Grab the latest pkbrew from https://github.com/gocario/pkbrew/ Copy the "pk" folder from the zip onto the root of your SD card.
Installing CIA: Unzip the PHBankManager zip file. Copy the "PHBankManager.cia" to your SD card. Launch your favorite CIA installer, and install the "PHBankManager.cia". NOTE: PHBANK.CIA MUST BE INSTALLED FOR THE CIA VERSION OF PHBANKMANAGER TO WORK PROPERLY!
PHBankManager Usage: Press "B" to create a new bank file. Use Up/Down to choose the bank file you wish to use. Press "A" to select the bank file to open PHBank with. Press "Start" to exit without selection.
After pressing "A", the 3dsx version will quit, allowing you to run the PHBank 3dsx with the selected bank.
After pressing "A", the cia version will automatically launch the Installed PHBank CIA.
For some reason, creating a new bank file saves a temp file to your SD card. (In "/3ds/PHBankManager/" for 3dsx users, and "/" for cia users.) The �permatemp� file has a numerical name that is nine digits long, and is zero bytes large. These files are not used with PHBankManager, and do nothing, so deleting them is okay. Or keep them if you enjoy seeing all the numbers.
Credits: Thanks to Rinnegatamante for the lpp-3ds source and samples on how to use it, as well as Gocario for PHBank! Special thanks to /u/ItsProfOak AKA CollectorTogami for testing the Alpha version of this script, as well as asking me to make it! (It gave me a chance to relax a bit!)
Always make sure to backup your original bank file at �/pk/bank/bank� before using PHBankManager for the first time! I am not responsible for any damage this does!
Thanks for checking out PHBankManager!
