Rgh 1.2
TX made R-JTAG+, I resurrected the RGH1!

I can't guarantee anything. Maybe each Xbox requires its own timing value. But the results on my Jasper are really good.

don't forget to use RGH2 freeboot and ECC images!! That's NOT just another RGH1 code

Wiring is the same as RGH1, but with POST_0 instead of POST_1:

The development is in very early stage, so of course there will be improvements.
I don't know why, but this thing works only with external 48 MHz quartz, and doesn't work with HANA clk point.

xsvf file for jasper (for matrix, coolrunner, other devices compatible with old RGH1 xsvf files):
matrix / coolrunner version
squirt (48mhz), SVF
squirt (48mhz), XSVF
