We are happy to announce the release of a new set of RGX XSVF Timing files along with tuning options which have been taken from the code of the CR3 Pro along with added DemoN CR_EN Support. Feedback from testers has so far been phenomenal. many had Trinity's and Corona's that simply wouldn't boot with the old 64 based RGH2 methods or were very stubborn or slow and now they boot in 1-5 glitch cycles every time. Some of them reported times equivalent to the CR3 Pro Perfecto! score (cycles that would usually look something like this 1,1,1,2,1,2,1).
So if you have a DGX (or if you don't you can buy one now as we released a bunch of new stock this week), then you convert it to be almost as high performing as the fastest glitch chip in the world – the CR3 Pro. Some installed and got instant results, others had to do a fair bit of tuning – but EVERYONE ended up with great results. We have compiled a comprehensive guide for you to follow so you can get the most out of your DGX-RGX conversion.
Tools Required:
DGX v1.0s or DGX v1.1s
JR Programmer (any version – requires latest fw update) or NAND-X
Optional: Ceramic Caps for Tuning (10pf, 22pf, 30pf, 47pf, 68pf, 82pf, 100pf)
Optional: POST QSB (Trinity & Corona v1, v2)
Optional: POSTFIX Adapter (Corona v3, v4)
Software Required:
J-Runner v0.2 Beta Build 288 Core Pack (The new XSVF files and latest JR programmer fw is included in this release) - Download Here
Wire Info:
POST_OUT: Recommend length is 12cm. We also recommend you use 24awg.
CPU_RST: Recommended length is 10cm. The DGX v1.1s includes an IPEX u.FL Double Shielded Cable.
Note: For CPU_RST it is high recommended that you use the POST QSB (For Trinity and Corona v1 and v2). It is much easier to tune the shape of the wave with just one wire length.
DIPS Info:
The DIP switches are not used in any way once you have converted your DGX to an RGX. Some users say that they get better results with all DIPS ON. I personally think this is nonsense as I know how the code and hardware is design and none of the DIPS are even touched – but it doesn't hurt for you to try it

Programming the DGX:
First make sure your JR Programmer has the latest firmware (Select Tools > Update JR-P fw). If you have a DGX v1.1s, there is no JTAG pin header, you will need to wire up your JTAG cable directly to the JTAG solder points on the PCB. They are clearly labelled in the diagram below.
You can use a Xilinx LPT cable or a JR Programmer (with latest firmware) to program the DGX with an XSVF timing file. (You can also use the Xecuter DemoN or NAND-X if you wish).
Load up the latest J-Runner and click the "Flash CoolRunner" button.

You will now see a list of timing options for the RGX. Each of these use the same computations as the CR3 Pro. The settings are dynamite and couple with the speed of the upgraded Xilinx IC and specifically manufactured crystal, the speed settings are so accurate that, apart from the CR3 Pro itself, the RGX will beat any RGH mod out there when setup correctly.
There are 3 timing options for the Corona and 4 for the Trinity. Each setting can be fine tuned with a specific ceramic capacitor – just like the CR3 Pro, to give maximum results on the hardest to glitch console.
