Questions that do not deserve a thread

[Fudoh]

S-Video has just two signal pins along with two ground pins (which are often connected inside the cable), so you can't route a RGB signal over this connector.

The WM also has a multi AV out, but I don't think you'll be able to find a matching plug. The MIDI port though is extremely easy to work with. Standarized plug which is easy to get, big pins. Really easy. On the Midi out you have 5 pins which are perfect for RGB+Sync+Ground. And you can get unmodified audio from the RCAs.

I just recently purchased a JAMMA extension from Mike's Arcade shop and while the whole set looks pretty good I'm having an issue. Every single button and other directional movements work except left. For instance, if I play Mushi or Futari 1.5, I can't move to the left.

Within the Test Menu > Inputs, nothing is showing/activating to that direction. The pins are aligned properly into the HAS, the harness is making proper contact with the JAMMA; I even turned up my volt from 5.0 to 5.1 just to temporarily test it out.

My setup is a HAS with UD Decoder; my boards work flawlessly when the HAS is directly attached. Any suggestions on how to go about this?

Gotcha.

With only 5 pins, I assume it's just like you said, but the picture shows "Blanking" for SCART as well. So I do or do not need to pull the "Blanking" line from pin 12?

I intend to make a MIDI -> SCART cable for use with my matrix.

Then for the cable it's just:

RGB to the RGB pins in the SCART connector
Ground to pin 18
Steal the sync off of the S-Video connector for the last pin of the MIDI, and out to pin 20

[Fudoh]

wether you'll need a blanking voltage or not will depend on the type of monitor you're using. So which display is it ?

My entire chain is:
Shinybow 6:2 SCART Matrix -> OSSC -> LG OLED55B7A

[Fudoh]

Then you don't need to wire up pin 16 of the scart cable. RGB, Sync and Ground are fine.

Is it true that crt tvs under 20inches (the 14inches ones maybe) have very good geometry ?

[bobrocks95]

Is it true that crt tvs under 20inches (the 14inches ones maybe) have very good geometry ?

It's true that they tend to have better geometry than larger sets. I wouldn't say good geometry on any CRT is a guarantee unless you have a BVM where you can digitally adjust all aspects of it.

Curved screens have better geometry than flat screens.

A component cable with one vga/d-sub to 3rca adapter and three rca to bnc adapters, or a vga cable with a vga/d-sub to 5bnc adapter.

I got the 5 bnc connector cable. What do I do with the 5th connector though? rgb+sync only needs 4 connectors.

[Kez]

VGA normally uses HV sync instead of composite sync, meaning there are two sync lines. If your 3Dfury is outputting RGBHV then you will need to use all 5, if it is sending out RGBS then it will be on the H connector and V will not need to be hooked up.

[DejahThoris]

Super helpful replies

Thank you so much for your help. I've only just set up my OSSC at all, haven't messed with settings beyond 5x and scanlines, but here's my RG-M1 RGB mod results!!

The weird bowing on each side is my phone, not the video on the screen. I don't know why it does that.

Quick question: does the Framemeister support Micro SDHC? I know that it does not support SDXC, but I am not sure about HC. Anyone know?

How do I know which one it's outputting? Also what do I do with the two syncs if I need to connect both?

I'm pretty sure the BVM needs RGBS. It does take component however.

IIRC the 3DFury can output RGBHV or component, so I think you have two options:
- RGBHV into a sync combiner to output RGBS
- component (YPbPr)

I think if you set the 3Dfury to output component, set the BVM to component and don't hook up sync at all, your breakout cable will work. I don't have personal experience with that particular setup though.

EDIT: Or this, from the 3Dfury manual:

EDIT: Or this, from the 3Dfury manual:

I was always told using one of those joiners is bad and over time can damage equipment (something about the signal being too high powered or some extra step being needed to properly join the H and V sync signal...or something like that)?

Hi guys,

I have a quick and easy question:

Do you suggest buying a Sony PVM 20" 20M7MDE for 300 € ?

...I know it's a PVM (= medical use) and It's 100 hz.
Any suggestions are highly appreciated!

Thank You in advance!

(it's my 1st post but I've been reading you for a while)

So the A series BVMs use newer components and are generally considered an upgrade from the D series? I've heard that some game consoles have sync issues on an A series BVM due to the lack of a VCR Mode?

Also, is it true that some cheap TVs with only Composite and S-Video inputs will re-combine the sepearated Luminescence and Chrominance signals from an S-Video cable back into a composite signal?

[Fudoh]

sure. just means that you're using a luma signal as your sync signal. Still gets routed to the composite video/sync pin.

I would consider them a downgrade. The card which is needed to input 240p into them is around $2,000.00 - they only made a couple hundred of those cards if you believe what people say online – and that same card does have sync issues on a bunch of systems so I honestly don't know why anybody would want an A-Series unless it was super cheap or free.

I forgot to say that I'd use the PVM 20" 20M7MDE for 240p and 480i consoles (from Super Famicom to PS2) with RGB cables

I recently bought a Sony BVM-20F1E (PAL version of BVM-20F1U) and I want to connect a PAL SNSP-CPU-1CHIP-01 or PAL SNSP-CPU-1CHIP-02 using RGB cables from retrogamingcables.co.uk
I watched the RGB masterclass from 'My Life in Gaming' but I still have some questions before I make subsequent purchases.

1. Which cable should I get for this tv / console(s) combination?
- Nintendo Super SNES RGB SCART (PAL) wired for composite sync CSYNC
- Nintendo Super SNES RGB SCART cable SYNC on LUMA for PAL console
- Super Nintendo PAL SNES RGB SCART PACKAPUNCH PRO CABLE

2. I should get RCA / PHONO Audio Breakout because the BVM does not have speakers, right?

3. Should I get 75 Ohm BNC terminators for this BVM?

4. I connected my PAL Wii using component cables (480i), recently they added RGB cables for the Wii to their product line-up, will this be an upgrade compared to my current component setup?

*edit got replies on reddit.
Decided to go for SYNC on LUMA for PAL console, don't need audio breakout because the female SCART to BNC breakout cable has audio, need 75 ohm terminators for a BVM and decided not to get Wii rgb cables because the difference would be insignificant for the price.

Can all models of the Sega Genesis be overclocked?

[strygo]

I recently picked up an Atari Jaguar and a standard SCART cable from RGC. I am seeing video interference on my displays. Before I do a more thorough investigation, has anyone run into this? Are there any known issues with the original Jaguar power supplies? The cable isn’t fully shielded, so unless there is a known power supply issue, I will probably pick up a shielded one when Retro Access starts selling them in the new year and see if that fixes my problem.

Thanks,
Steve

Has a fix for MD2 jail bars been found yet ? besides modding with a bypass board I mean.

IIRC on the MD1 lifting pin 50 on the VDP worked well, but I don't know if the same can be done on the MD2...

I have two PAL VA1.8 MD2's here (w/ 60Hz switch), both with heavy jailbars I'd like gone. I'm using 'cleaned up' original scart cables (parasite-heavy voltage booster and widescreen switching cut-off and 5V bypassed) everything's fine save for the bars.

[SamIAm]

Has anyone ever tried building an S-Video to RGB converter with an RGB decoder IC like the CXA1621S? It seems like it could be very useful for consoles without RGB outputs on displays without S-Video inputs.

[Guspaz]

The problem is many such chips were discontinued long ago. That Sony chip seems to have been discontinued decades ago.

[SamIAm]

Ah, but I live in Japan. They're two for 500 yen on Yahoo auctions.

EDIT: Looking closely at the datasheet, it seems that that particular IC isn't made so much for direct input of S-Video so much as YC-separated composite video. The signal levels it's expecting are odd. Still, it might be fun to play with.

I have an opportunity to pick a Xbox One pad on the cheap. I already have a wired 360 pad and was wondering if the Xbox One pad will offer any improvement? For shmups, arcade games and also general PC gaming.

[TransatlanticFoe]

It's a better shape for adult-sized hands. Really comfortable and I would recommend over the 360 pad were it not for:

D-pad, whilst less likely to hit unintentional diagonals than the 360 one, is clicky and uncomfortable. Quite annoying for shmups really
Shoulder buttons are flimsy and easily broken, so not as good for general gaming either
