Hello.
I am understanding I am not to write a program that allows you to import/export PNG files to and from P8 cartridges, so I wrote this in an attempt to assist other Pico-8 users of the educational edition since they cannot import or export graphics or music.
It uses a variance of the graphics for the little library I wrote, the first Picotron program written found HERE:
https://www.lexaloffle.com/bbs/?tid=50942
I exchanged the spider and bomb for Forest (tree) and rubble which can double as mountains. There are some miscellaneous sound effects and I also added a musical note player that overlaps the notes as they play so they sound better.

Users of the educational edition of Pico-8, you can copy this code by clipboard and paste directly in your source-code. It not only has 128-characters and game sprites but a fairly robust library of sound effects and the ability to play notes overlapping each other.
If you found this helpful or have further questions, please let me know.
Thanks !

You are more than welcome, @AntiBrain.
I realize I could just post a cart making use of the spritesheet and SFX table normally, yet by keeping the entire program to 7-bit text ensures that any part of it can be easily ported to any other Pico-8 educational edition code without having to enter either GFX or SFX editor.

This is very useful for those of us using the Pico-8 Educational Edition! The import/export restrictions can be tricky, so having a library that simplifies graphics and sound effects is fantastic and will really help with learning. By the way, if you're also a part-time student like me and don't have enough time to do your homework, you can visit EduBirdie the professionals there write great essays. What will help to relieve you and better manage your time. The sound effects and sheet music addition are also a nice touch. Thanks for sharing!
