XRGB-3

The passthrough input is fine, but you don't want to add processing to 480p inputs. In theory B1 doesn't add much processing to 480p sources, but noise is a problem and you'll overall see a signal degradation.

Jesus, now they tell me. This whole time I thought the xrgb 3 just acted as a pass through for 480p content.

what type of processing is going on through the vga port? I don't notice any signal noise (or maybe the gefen VGA to dvi cleans it up along the way) I play in b1 pretty much exclusively

Tokyo xtreme racer 2 and shenmue look fucking phenomenal, lol if you're telling me it can get better I think I'm going to have a stroke

Also related but I definetly remember reading on here that the psp should be set to through progressive output while in b0. Is the psp the exception to the don't run 480p through the xrgb 3 rule?

Don't pin me on it - it's been too long since I shelved my XRGB-3. Easiest way to tell is just by enabling the LPF option. If it affects quality then the input is processed.

For PSP you obviously want fullscreen output and the only way to get those 272 lines scaled to a fullscreen output is to enable the special D2 PSP zoom option and this only works in B0.

I found the passthrough and the VGA in to both produce a noisier picture than just bypassing the XRGB3 entirely for 480p content.

My XRGB-3 doesnt switch on properly anymore, when I press power the Standby and Power On lights stay on but nothing else happens.

I'v tried reflashing using Windows XP but I get a message saying:

"Write error rom=21B8 file=AFE7"

any suggestions?

Are you using the orignal PSU ? Just as with DVDO's processors, behavior like this is usually caused by the caps in the PSU going bad. Voltage starts to fluctuate and all kinds of weird stuff happens.

No, I bought a compatible UK power supply. I could buy another and test it was cheap.

brownvim · Post by **brownvim** » Mon Feb 02, 2015 9:18 pm

Iv ordered a new power supply, I don't think it's that though

Why do you think that it's not the the power supply?

If it turns out not to be the power supply then you might be able to flash it manually with an external SPI programmer.

It looks like for some reason the flash is getting corrupted or maybe the CPU bootloader/firmware is corrupted. It's easy enough to reflash the flash memory but I'm not sure how to initiate a CPU update from flash. With the mini it's just a case of changing a setting in the menu or editing a text file on the SD to initiate a CPU update. Not sure about the XRGB-3, never tried as I only needed to dump the flash at the time.

The power supply does seem like the likely cause though.

I hope it just is the power supply. There were days it would do this (2 lights) but I would just turn it off and on again and it would be fine.

Have you tried resetting it? Try taking the DC in power jack cable out of the back of the XRGB-3 and do the standard reset procedure by reinserting the power jack while holding in the buttons until the lights blink (i like holding in the buttons for a while before i insert the power jack to be sure): http://junkerhq.net/xrgb/index.php/XRGB ... XRGB-3_.3F

Maybe your power on just doesn't work if you've changed the standby menu setting previously. If your firmware is corrupt this properly won't do anything.

There's also a way to start the backup firmware. Some talk about the two methods here if you don't already know.

I have already tried the reset, it doesn't respond as it normally would. The 2 lights stay on.

I have booted it using the seconday firmware by holding PCinP button whilst you power it on. This is the only way I can get my PC to recognise it to flash the firmware. But the flashing always fails.

Damn.

I hope you get it fixed somehow.

Power supply came today and it booted fine first time

Thanks for the help guys!

It's amazing how high the failure rate of those chinese switching PSUs actually is.....

brownvim · Post by **brownvim** » Wed Feb 04, 2015 11:50 pm

The one Iv bought now is branded Panasonic, hopefully lasts longer.

Edit: says "for Panasonic" and made in China...

post a link. Always good to have valid buying options on hand. It's not this easy to find a good PSU for the XRGB-3.

The tip will need to be replaced but that's what I got and works fine.

Just ordered a toro vga box for my dreamcast, would outputting via scart into the xrgb 3 game in produce a cleaner image than just running vga out from the toro into the d in 2 port?

brownvim · Post by **brownvim** » Thu Feb 05, 2015 10:16 pm

It's not been something Iv been able to try as I have the Hanzo model.

There's not a massive difference from going VGA pass through with the XRGB compared to straight into my monitors VGA input.

That's not what I heard according to fudoh and others, I won't be able to test for another month or so until my box and transcoder arrive so I can compare

brownvim · Post by **brownvim** » Thu Feb 05, 2015 10:53 pm

There's a difference, I have it going straight into my monitor.

Not huge though. I remember trying it and it looked a little sharper and less noisey

Fudoh · Post by **Fudoh** » Thu Feb 05, 2015 10:57 pm

Not sure if the XRGB-3 can even accept 480p in RGB through the Scart input. I don't think so. It's likely 15khz for RGB only and 480p is just for component.

Would it damage the port if I tried?

Fudoh · Post by **Fudoh** » Thu Feb 05, 2015 11:39 pm

I can't imagine. Should be same as feeding 480p component without setting the options to YPbPr.

I got my XRGB 3 today. A tip for those wanting one. Zero 64bit OS support. You'll need a virtual machine. USB 2.0 and 3.0 didn't matter at least on my machine.

I'm a bit confused about what the Wiki says concerning B1 mode. Do I need to flash the firmware anytime I want to switch from B0 to B1? B1 mode seems to work for me with scanlines and all. Just going into the menu > switch FPGA > reset. The firmware on CPU Ver still say 2.31. Am I doing something wrong here?

brownvim · Post by **brownvim** » Fri Feb 06, 2015 9:56 am

You just need to flash both firmwares once. You can then switch between them by the onscreen menu.

Ideally if you can stand the cable clutter I'd go SCART to GAME-IN (for all 15khz) and then D-SUB15 directly to your display (for all 31khz/VGA).

I flashed mine on with my laptop on Windows 7 x64 a couple of weeks ago. I do seem to remember not being able to flash with that same laptop before though. Maybe something has changed.

brownvim · Post by **brownvim** » Fri Feb 06, 2015 4:00 pm

Is there a way we can get the new firmware translated to English like we did before for 2.31?

Using Win7 here and I couldn't get it to send info to the xrgb. The updater would crash soon as I tried. Worked no problem with XP in a virtual machine on the same computer.

Hopefully. Is there anything important in the newest update? I saw that while I was updating mine but just stuck to 2.31 since it's in English.
