History

The chip was first considered a rumor or April Fools' Day joke, since it was said it supported direct booting of media instead of having to swap with an original disc, which none of the other modchips available at the time could. Qoob Chip however was released with all its said features on April 12, 2005 twenty two days after the first announcement of the product.[1]

Versions

There are two versions of the chip: Qoob Pro (which was the first to be released) and Qoob SX. Both versions share the same core, the pro version however have features which the SX does not: bigger flash memory and a USB connector for easy updating.

Pro version

The pro version of the Qoob chip is intended for developers and/or advanced users. The biggest differences from the sx version is the USB upgrade feature and 16Mbit flash memory.

  • 16Mbit on-board flash memory for application storage.

SX version

Released after the pro version, the sx version is a stripped down version of the Qoob Pro chip, missing the USB upgrade feature and containing only 1Mbit of flash memory. The sx is equipped with a backup read-only BIOS preventing users or malicious code from "breaking" the chip.

Hardware and installation

Both versions use the Actel FPGA, a flash memory (size depends on version) and a cable connector for the cables which are to be soldered onto the Gamecube mainboard. The Pro version also includes a flex cable connector, a highspeed USB controller, a USB connector board and an integrated status LED. Since there is a connector for the cables integrated to the chip there is no need to solder the cables onto the chip, eliminating accidental burning of the chip. There are six wires which are to be soldered onto the Gamecube mainboard, making the Qoob chip installation difficult for some users.

BIOS

The Qoob chip contain a BIOS which is upgradeable through different methods depending on the chip version. The official BIOS (Version 1.0 Release Candidate 4) is available through Qoob's official website, this version does not support unofficial versions of licensed products. The two chip versions have different BIOS versions, they however follow the same version number. After the release of Qoob BIOS 1.3c on 31 August 2005, the Qoob developers have since not released a new BIOS.

Game backups

The designers have made no attempt to stop this from happening, although they are officially against the pirating of software.
