Five months after the v500/v500a firmware removed all homebrew capabilities, while SNK Playmore and Tommo are busy arguing about the contract they once made, finally a jailbreak hack has been released. On the Facebook page Neogeoxjailbreakhack you’ll find links to the hacked image (based on the v500a firmware), instructions and sample content for a SD card with settings for many emulated consoles and arcade systems.
Systems supported so far: Nintendo Famicom/NES, Super Famicom/SNES, Game Boy Advance, Game Boy/Game Boy Color, Sega Mega Drive/Genesis, Master System/Game Gear, Atari 2600, Capcom CPS1/CPS2, Sony PlayStation, SNK Neo Geo.

To upgrade the Neo Geo X with the new capabilities you’ll need the yet to be released NGX Tools – or the official rocket cable and a X-Card or a similar modified SD card/adapter.
