I was tempted to name this tool "Nah!" for "Not A Hex-editor!" but eventually I added editing features so I decided for Binmap. It mainly assists in analysing and documenting binary data files.
Remember Hi-Octane by Bullfrog. Yes! It was the year 1995.
P8Coder is a handy little tool that replaces the lua code in pico-8 cartridges (p8) with the code you write in P8Coder (Windows only).
It allows to group functions (any code actually) that belong to the same entity/unit in your game and lets you have functions (any kind of code sections) as tabs.
When writing to the cartridge it concatenates all code to one large lua code block as you would have when writing the cart directly in the p8 file or in pico-8.
Had some time, made this PICO-8 edition of Jetpack, 30 hot levels and various enemies.

Work of a weekend ... simple tilebased editor-like engine with pathfinder and no gameplay.
Pico-8 is awesome!
It's a complete game editor in a fantasy console including pixel art paint program, sound samples tool, music tracker and code editor (LUA script). And all of that in a 128x128 pixel canvas (scaled-up) desktop application (win/mac/linux). Cartridges can be stored as PNG images files and loaded by anyone who wants to look at its source (with pico-8), artwork, sounds and code. It is totally recommended to anyone who wants to start programming because LUA is very simple! SHOW
