Yeah - doesn't matter what I do with the dials, the effect shows no signs of changing at all.

Here are some more images that might give a clearer indication what is going on:

Here's what I have tried:

various consoles->gscartsw->Sync Strike->Extron->BVM
various consoles->Sync Strike->Extron->BVM
Dreamcast->Extron->BVM

They all give the same results, this weird distorted picture.

The only thing I can't do currently is test the Extron on another device, as I don't have a BNC->SCART connector, only SCART->BNC. However, I did briefly connect the Extron to a JVC monitor in the past and did not have this issue.


So I picked up another Extron unit, a 160 xi. To my surprise, the same thing happens on my BVM. This weird picture with all the colours dark/out of place.

However, on this Extron I get a great picture when I flick the DDSP switch (the 201 just loses sync in DDSP). Only, in doing so I lose the ability to adjust the image and the curve at the top of the screen is still present (I guess SERR and DDSP don't work together or something?). It looks like there is something about the BVM that stops it from working with Extron RGB interfaces..

Can I play MVS games on an AES by using a NEOSD AES and the ROM image?

Rom images are the same.

The correct way to do this is install a Universal bios in the AES and put it into MVS mode.

Xyga - I've got a PAL SNES scart cable wired for sync on luma. Bought from thefoo.83 maybe around one year ago. I have no use for it, pay for the shipping it's yours.

Thankd X.X I'll try to fix mine first but I'll keep that in mind.

As Syntax said, just use the unibios. There are a few minor issues when playing some MVS games on an AES, however.

http://unibios.free.fr/knownissues.html
Quote:
AES only issues

  • There are no attract mode sounds for many games when running in MVS mode. This is because they read the demo sound soft dip from the backup SRAM which the AES doesn't have (this problem exists on the DEBUG bios also).
  • Some early games like Nam1975 for example will have corrupted 'How to Play' screens when in arcade mode. This is because the AES does not have the needed character font built in that the MVS has.
  • When in USA arcade mode some games will have a corrupted 'Winners don't use Drugs' screen. This is because the AES does not have the needed character font built in that the MVS has.

At first I posted on the XRGB-Mini thread but I discovered it's not related to the mini, so I post it here.

I bought a new psp for it's tv out (it's a 3k) and I have some issues. I use a third-party component cable.

With the XRGB-Mini I have some "extra garbage" on the top, on the PSP Menu. Also the screen is shaking, and some game have black screen or heavy shaking at certain moments.

I will talk about the XMB menu because it's easier to explain :

It seem related to the colors and types of the theme I use :?: :
Some of it make the menu perfect without any issues (no shaking very clear without any issues)
Some make the screen do like a resolution switch (2-3 seconds)
Some make the screen shake
Some make the whole screen black and I need to change the theme color to have an image again.

At first I wrongly thought that my TV (using component input) didn't have issues, but discovering the theme thing made me discover that my TV also have problems.
On my TV the shaking can even be worse and the whole menu is slowed down in top of that.
And the same strange thing, on certain colors the shaking/slowdown stop, on others it's very problematic.

Do you think it's a faulty cable or a faulty console ? Something I can do ? :(

Could anyone suggest any decent 3rd party AC adaptors for Genesis Model 1? Is the original SEGA one still the best bet? Would love to get something smaller and a bit more efficient if there aren't any major drawbacks.

Need 2 to power a Mega Drive / Mega CD

For US 110 Volts

A RetroDC if you're fine with the price and don't mind waiting like a month to get it?

I made my own hyrda power cord for the genesis, 32x and CD out of a 12VDC 5A power brick and a soldered together a 3 way harness with a 2.1mm socket for the brick and 3 outputs for each sega thing. CD and model 1 are reverse polarity and they both use 2.1mm plugs, model 2 and 32x are center positive and use 1.7mm plugs.

Cost me nothing since I had all that stuff lying around - a 9VDC (3A min) brick would be more "correct" but the regulators in these things are good up to 25VDC iirc.

Better not let those plugs touch ever..
I was considering the same approach but worried about ground loops.

I made the CD one a fuzz shorter so it can't touch the other two when they're not in the console :D

Those 12v 5a powerbricks are reapropriated LED driver boards. The brand name is Olive Leaf.
When you opened it I bet you found chopped off wires and such. You can buy the boards for sub $4 delivered.
If it looks anything like this then it can only pull 3a. Any more will shut it down in a few minutes.
https://www.aliexpress.com/item/2PCS-AC ... 50586.html

I put one on the scope last night and compared it to an old linear Sega PSU and the 5a power brick actually had less ripple.


Considering boxing a few of these 3a ones into one fan cooled unit. They seem to have a better design and heatsink.

I actually didn't open the brick, I just put a 2.1mm jack on my harness to plug it into. You're right about it coming from an LED application though - the bricks I have came with a batch of LED backlit signs we were working on.

3A of current should be plenty for the megazord regardless

(I'm surprised the old sega psu were linear I assumed they were switching)

BVM/PVM question:

Is it normal that the monitor would consider the OUT BNC as an input? Or that it links it with the IN in some way?

Like, on my PVM that has mono sound I was able to get both tracks when plugging L in IN and R in OUT RCA.

And now I just tried on the BKM-129x card at the back of my Multiformat BVM to put the SYNC cable on the OUT of the green and it syncs, as if I had put a T-BNC adapter on GREEN to merge SYNC and GREEN.

Is it that way by design? Is it dangerous?

Id say the outs are just hard linked to the ins without isolation or amplification from your experience, so to do things safely...

For audio - Put something around 1.2k inline on each channel.

For SOG - Put a 100uf Electro cap on the green line and a 680R resistor on the sync line.

Currently I have my machines plugged in a gscartsw_lite => SCART to BNC => PVM/BVM.

Aren't these sufficiently shielded to produce correct signal? Is it any different than using this for my audio and a BNC T connector? I just don't want to damage the BVM or the BKM card, I'm just surprised it works actually.

You don't simply connect left and right audio, likewise with green and sync.
Its just not cricket.

Add the passive components and be happy with a better picture and audio.

**EDIT**
Probably a good idea to check for continuity first between the ins and outs of your monitors to confirm they are in fact bridged.

Does anyone here own a Naomi cartridge that's been converted to another game (gd-rom based)? Is there any difference with respect to the original gd-rom? Can you save your progress in the game? Anything one must be aware of before buying one - maybe feeding a higher voltage to some components like in the case of some multicarts/everdrive? Anything?

Hi!

I bought a new monitor a while back and it only has HDMI-input. I have a few old consoles (AV Famicom, SFC, Mega Drive and more) that I would like to play - is there a good converter out there for this? HDMI to scart?

I'm not very picky with the absolute optimal scaling/sound/whatever. If there is a multi-purpose converter for all my trouble that has a decent price tag I'll settle for it.

SCART to HDMI converters exist and are relatively cheap. You can find them easily on Amazon.

Just be sure you pay attention to the correct direction, as they are typically unidirectional: a SCART to HDMI converter will accomplish what you want, but an HDMI to SCART converter won't.

Ah yes, you are correct of course ^_~ But most of them are rather solid and don't have severe input lag or anything like that?

Your best bets for performance and quality (at the cost of...cost) are the Open Source Scan Converter and the Micomsoft Framemeister. There are threads dedicated to both here in the Hardware forum.

check here: http://retrogaming.hazard-city.de/ (scroll down, down...)
The HDV 8S (HD Video Converter Scart / HDMI) might do it.

Can't seem to find that specific one Xyga! Do you think this one would work instead?

https://www.deltaco.se/produkter/deltac ... CART-HDMI1

(sorry, Swedish website)

Costs about 90 or so Euro.

The square black one (good) exists under different sub-brands apparenly, like Linkfor, Vcando, Elephas, Mcbazel, Gam3Gear, Flylink, Zilong...

I can't talk about the other one you linked, but I find it expensive as it probably doesn't offer better quality and possibly worse (decent quality is rare

Good luck, but really beware that the OSSC set the standard so high that pretty much everything else below it now is technically a waste of money IMHO.

(well, it's good if you find that square converter for like 30~50 zeni at most, but if you spend like 100 it'll be a waste)

Yeah I can see that, but OSSC seems pricy and again I'll be happy with going for budget options for the time being.

1. Do any PS2 revisions have better RGB output or audio than other PS2s?
2. Can you restore the iLink port and HDD functionality to a PS2 Slim?
3. Can I import a Japanese PS2 and play it in the USA without any issues?
4. What is the best PS2 model? Any pros/cons to the fat vs. the slim?

How much input lag does the HD Fury Linker add? (searched online but couldn't find an answer).

Also while we're at it : just how good is it's upscaling? (I don't require integer scaling, I'm fine with interpolation as long as the algoritm does a very good job)
