Hi,
I have a brand new Arcade Jasper (manufacture date 2009-08-08) with dashboard version 2.0.7363. The internal memory is 322MB(512?). Do I have anything to worry about? Is my arcade hackable with this JTAG hack? Is my motherboard compatible? Thanks for your help

The SPI is fully compatible with all motherboard models (same solder points in all motherborads)
The JTAG hack is "blocked" in new manufactured motherboards (blocked at the bootloader level)
To be sure what bootloader do you have... you can make a dump of your nand with SPI... and later, open this dump in "360 flash tool"
360 flash tool can show you info of the dump contents (Cx sections) even without your CPU-key
360 flash tool actually cant open jasper nand dumps, but if im not wrong... a new version is in development
If your bootloader works with the JTAG hack... then you can write the
hacked_jasper_nand_image.bin (or whatever) in your nand to retrieve your CPU-key (and other efuse security data)
