GBSFX Studio

A SOUND EFFECT STUDIO ON A GAME BOY CARTRIDGE!

Browse 250 ready-made sounds across a range of common categories, edit any of them with up to eight sliders, and keep your favorites in a 60-slot bank. The bank saves as an FX Hammer .sav file, and drops straight into a GB Studio project.

Pick a type, a sound, then a variant. Open the editor and edit its properties using sliders to change pitch, echo, length and more. Hit GENERATE to randomly set the sliders and produce a twist on the default sound, or MUTATE for a small random nudge.

 Save any sound into one of 60 slots.
 Copy the .sav into your project's assets/sounds folder.
 Play it in GB Studio with a [Play Sound Effect] event.

Personalize the interface with 20 color themes (color device only). 

Try it before you buy it. The free "Jam Kit" version is the whole studio: browse, the editor with GENERATE and MUTATE, the 60-slot bank, all 20 themes and the GB Studio export. It comes with a starter set of 30 sounds to shape and save into your own games. Every other sound is still listed, grayed out, so you can see the full library of 250 before you upgrade. Download it below, or play it right here on the page.

GBSFX Studio is a single .gb file that is compatible with:

• Game Boy Color and Game Boy Advance: full color, with 20 themes to choose from.
• Original Game Boy, Game Boy Pocket and Super Game Boy: a 4-shade gray version with its own title screen.
• Emulators and flash carts: anything that runs Game Boy ROMs with battery saves.

Made for GB Studio. The bank is an FX Hammer .sav, the sound effect format GB Studio imports. Drop it in your project's assets/sounds folder and play any slot with a [Play Sound Effect] event.

An instruction booklet. The download includes a 16-page manual (PDF) in the classic Game Boy booklet size (115 x 85 mm), illustrated with screenshots from the ROM. It covers getting started, finding a sound, the editor and its actions, saving and the bank, settings, importing into GB Studio, keeping more than one bank, all 20 themes, and the full list of every sound and variant.
