Jasper is the codename of the fifth motherboard revision for the Xbox 360. On Jasper motherboards found within Arcade SKUs, this Xbox 360 Motherboard revision features an onboard memory unit to facilitate the NXE Dashboard.

The connections required to dump/flash the NAND are the same as all previous models.

Performing the SMC Hack requires the same wiring as Zephyr, Opus, and Falcon mainboards. This is a slightly different set of connections than those required for the Xenon mainboard.
