Question for an upcoming video: (Patreon)

Hi there Patrons!! In a video I'm currently working on, I'm going to be able to store digital things inside of a pokemon save. However, I'm unsure what would be the best thing to do for the video. I have a few ideas, but would love to hear if you have any!!

Basically, I will be able to store the binaries of any file that is 10kb or smaller.
Some Ideas I've had include:
- Small ROMs
- Pictures
- Hyper-compressed, short videos
- encrypted stuff
- executables
etc.

Any fun ideas are welcome!! Bonus points if they would make the title engaging!
