What's Been Done?

• Code execution through patched firmware
• Portable debugger patch with brute-force RAM searching & patching
• Patch RAM code to enable instant read/write/exec abilities over USB
• Complete RAM and flash dump (1GB, 67mb)
• Extend 14 minute record limit
• Downgrade lenses stuck on buggy official firmware
• Read IO: buttons, gyroscope, accelerometer
• Fix commonly broken buttons with button remapping
• Documented hidden scripting abilities
• Draw debug text and rasterizer objects
• Interface with embedded internal SQLite
• Graphics rendering onto OpenGL buffer
• Background task creation, deletion, semaphores, task hooks, events
• Primitive card speed tests (capped at 35mbps)
• Gryoscope controlled Tetris, 7fps DOOM port
• POSIX compliant compatibility layer

Hacked Models

• X-A2 @ 1.30 (Bin loader, USB code runner)
• XF1 @ 1.01 (USB code runner)
• Firmware downgrade has been tested on some lenses. (same firmware format used)

What's being worked on?

• Researching less intrusive methods for code execution
• Creating a custom menu with apps, scripts, and real time patching and tweaking
• Bypassing error codes and remapping buttons to 'repair' broken or flawed cameras
• Reverse-engineering and tweaking imaging and video code

Would it work with my camera?

FujiHack will only ever work on Fujifilm X/GFX/HS/F/Z/Pro cameras. See the unsupported models list. In general, FujiHack does NOT support the XP and S series Fujifilm cameras. The S Series has already been hacked by CHDK forum members.

What is it written in?

The firmware debugger patches are written in ARM Assembly. Most Fujifilm cameras run a custom ARM v6 SoC. Everything else is written in C.

When will you work on X?

Fujihack has and will always be non-commercial, hobbyist, and therefore will have no plans or deadlines. If you desperately need a feature on your camera, hacking it should be a last resort in most cases.
