FAQ

Why should I use an XRGB-2 plus ?

Full answer : Deinterlacing Classic Videogames (by Fudoh)

Short answer : XRGB-2 plus is perfect for old school gaming (Nes, Super Nes, PC Engine, ...) to PC / HDTV monitor. XRGB-2 can also be used as a transcoder though its input is restricted to 480i/525i. XRGB-2 plus outputs one resolution - 640x480 VGA. If you are looking for a good deinterlacer/upscaler for modern consoles, buy a XRGB-mini FrameMeister.

Where can I buy an XRGB-2 plus ?

Good luck finding a new one nowadays. The XRGB-2 plus was succeeded by the XRGB-3 and XRGB-mini FRAMEMEISTER. It is best to try to source one of those units; however, if you really want/need a XRGB-2 plus the best places are eBay and other auction sites as well as specific shops in Japan.

What do I need to use an XRGB-2 plus ?

You need your game console, a TV/Monitor capable of receiving a VGA signal and appropriate cables to connect your console or SuperGUN to the XRGB-2 plus. The best option available is using RGB-21 cables, though in some cases this is not possible and you will need to mod your console to output RGB and/or build your own custom cables. You can buy cables from the same places you could buy an XRGB-2 plus.

The XRGB-2 plus has inputs for the following :

  • 1 x [[VGA] w/3.5mm audio] (passthrough)
  • 1 x [[D-Terminal] w/stereo RCA sockets] aka Component
  • 1 x RGB-21 (GAME IN)
  • 1 x [[S-video] w/stereo RCA sockets] (S IN)
  • 1 x [[Composite] w/stereo RCA sockets] (VIDEO IN)

How much does the XRGB-2 plus cost?

Suggested retail price for the XRGB-2 plus was ¥30,240 (~$335 USD); however, the street price was normally around ¥21,600 (~$230 USD).

How to reset XRGB-2 plus?

When the unit if off, hold the left (←) and right (→) arrow buttons on the unit (not remote) and press the power button.

Important : about GAME IN input (RGB-21)

Never directly use the European standard SCART cables with an XRGB-3 since the pinout is different to the Japanese standard RGB-21 ones, and damage might result due to voltage applied on signal lines.

How can I connect my consoles then ?

  • 1) Use RGB cables
    • if you use RGB-21 cables then there is nothing special to do
    • if you use SCART cables then you will not to make them "compatible"
      • solution 1 : buy a SCART to RGB-21 adapter
        SCART to RGB-21 adapter
      • solution 2 : mod your SCART cable to comply with RGB-21 Japanese 21-pin RGB connector (by GameSX)
      • solution 3 : Use a SCART to VGA adapter and use the D IN 2 input instead. You will need to change the "D IN 2 INPUT signal" setting to "RGB"
      • solution 4 : mod your XRGB-2 plus RGB-21 input to accept SCART cable

  • 2) Use S-Video cables.
  • 3) Use Composite cables.

How to make RGB cables

How to enable low screen resolution ?

Options → Low screen resolution → ON

XRGB-2 plus will be able to output at 320x240 (15 kHz) and 640x400 (24 kHz).

Note : this option should be used only with a classic japanese PC monitor (PC-988x and X68k).

Does XRGB-2 plus add input lag ?

No discernable lag.

What are those famous scanlines, why do I need/want them ?

In general, you should use a value between 127 (50%) and 191 (25%). Increasing percent will produce a darker image.

640x480 VGA Normal (4:3)

About D-Terminal

D type World Japan XRGB-3 support
D1 480i 525i yes

Note: The difference in line count is only because those standards count the control lines as part of the resolution of the video signal, which is technically correct; but those are invisible lines that carry information.


How to fix screen distortion ?

Doe your screen looks like this ?

scren distortion

Then you need to manually adjust the User Dot-Clock section.

V-Sync and stuttering

If you are experiencing stuttering or "hiccups" on horizontal moving objects that should not be there, you can most likely get rid of that by enabling the V-Sync lock-option.

(will make a gif animation explaining stuttering)

Various Bootleg PCBs RGB via SuperGUN 0 255 RGB-21 INPUT termination : 220 OHM

Which cable should I choose for the best quality ?

In general terms the purest the signal from the device to the display, the better. In several standards, modulation is used in order to fit several signals on the same cable path. This adds extra processing in both sides since the signals need to be modulated on the device and demodulated on the display.

Without considering other factors, the quality in optimal conditions for cables can be rates as such :

  1. VGA
  2. SCART/RGB-21/Component
  3. S-video
  4. Composite
  5. RF

Note : Component is also know as D-Terminal in Japan.

How to use arcade boards with XRGB-2 plus ?

Since arcade games use RGB as a standard, the XRGB-2 plus supports them out of the box. The only thing needed is a cable to plug your SuperGUN to one of the RGB capable XRGB-2 plus inputs. However, the arcade video signals need some attenuation, this can be achieved with the use of potentiometers in your SuperGUN if available or via the "RGB-21 INPUT termination" setting on the XRGB-2 plus (set to 220 OHM).

What is A/D level ?

An analog-to-digital converter (abbreviated ADC, A/D or A to D) is a device which converts continuous signals to discrete digital numbers. Wikipedia

Input level/sensitivity. The default of 255 is the least sensitive/strongest input level. Lowering the A/D level makes the A/D conversion more sensitive (for weaker video signal levels).
