Three apps for making original Game Boy games on iPhone and iPad.
Draw the art, write the music, and put the game together, then build the ROM and play it
right there. Everything they make runs on a real Game Boy.
They're in beta. Join one through TestFlight, and tell us what breaks.
The apps
GB Art Beta open
A pixel-art editor that draws the way the hardware does: four shades, 8×8 tiles,
and nothing a Game Boy couldn't show.
Layers, fill, selection, and Apple Pencil on iPad
Every unique tile listed: edit one and every copy changes
A count of your tiles against the Game Boy's 256
PNG in and out, and drawings in Files or a git repo
A tracker for Game Boy music: the four channels of the real sound chip, written note
by note and played as the console plays it.
Two pulse channels, a wave channel and noise
Instruments, effects and drums, per note
Songs go straight into a GB Editor game

GB Editor Beta soon
The hub. Lay out maps, place characters, write the story, then build the ROM on the
iPad and play it in the built-in emulator.
Maps made from GB Art drawings, kept in step as the art changes
Characters, portals, searches and the story behind each
Music and sound from GB Tunes
Build on the device; share the .gb

How they fit
GB Art draws the maps and sprites, GB Tunes writes the
songs, and GB Editor brings them into one game and builds it. Each works on its own;
the editor follows the art and music as you change them. No account, no server.
And one more thing
Somewhere in a workshop, a Game Boy is being built from nothing. Not emulated:
rebuilt, gate by gate.
