Scanline generator SLG3000

The HDFury 2 is confirmed not working properly for PS3 and DVDO Edge + SLG3000 @ 480p due to a sync polarity issue. HDFury 1 works just fine with the PS3, assumed to be working with the Edge. Future revisions of the SLG may have a DIP switch to alter polarity.

Just a quick question here, does anyone have SF 3rd Strike for PS2? I noticed this thing is accurate with Dreamcast, but when I tried it on xbox, it showed no matter what settings I run it through the game had inaccurate scaling. I had no problem with this on Alpha Anthology, so I really have to find out if the PS2 version is the one to get.

So I´ve finished the cases. I couldn’t decide so I made some more variations. Take a look at the doming sticker :slight_smile:

Didn’t see that sticker when I saw those pics in the blog - it’s great! Even if I can’t afford a SLG-3000 for now I’d like to have one of those at least :wink:

Received the case last friday. Assembled easily and looks great.

I don’t think I can play my old school games anymore without this device. :rofl:

some lecture, reviews and articles :wink:

I may be asking a completely stupid question, but here it comes: when using MAME, I don’t like either scaling modes the software offers. One gets blurry and the other too sharp. I am sure that scanlines would make things easy with my eyes, but what scaling mode would be better to use associated to the SLG3000 and what is the difference between the hardware scanlines generated by the SLG and the software scanlines added by MAME?

Hey wiseless,

hardware generated scanlines are much more qler :wink:

You give the answer yourself. Here`re some more points

  • Especially on scrolling games software generated scanlines tend to flicker I`ve been told.
  • SLG3000 is plug and play. Set your resolution to 640x480, connect your SLG and ready :slight_smile: enjoy your scanlines
  • No configuration needed. Have in mind other emulators needs their own configuration. SLG needs no config at all.
  • scanlines intensity can be adjusted with the potentiometer axis.
  • and more… :wink:

I`ve just released Version 2 of scanlines generator SLG 3000 on my ArcadeForge.de Shop.

This is cool always thought scanlines made those old sprite based game’s look a lot smoother than the filter options they tend to lump with the ports these days.

Approve!

VGA is both a cable connection which you’re already familiar with and [COLOR=#000000]a resolution. I think the resolution aspect of it is throwing you off. If I’ve been following everything correctly, the signal has to be a minimum of 480p for the thing to work in addition to using the VGA cable.[/COLOR]

I think it’s designed this way so it has the space to insert the scanlines without taking away from the image of the game. Inserting scanlines into a 240p image takes away half of the artwork. Forcing scanlines in a 480i game has similar problems, as the entire image would be covered up half the time, since every other line is blanked and interlaced signals alternate between even and odd lines.

However if you upscale those images to twice to progressive scan, you end up with the redundancy necessary to insert a blank line. Basically the end result would be 2x2 blocks being turned into 2x1 blocks to emulate the space being taken up by the scanlines, instead of directly blanking out 1x1 blocks that you should be seeing.

It should first be noted that RGB signals are also outputted byt the SNS-001 and the Pal Gamecube. Nintendo stopped using it in North America 'cause they realized we didn’t actually have the means to benefit from it.

Though to answer the question, I’m not too well versed in how arcade tech works but I think insofar as home consoles go it emulates the scanlines you’d see in interlaced material on the CRT televisions these consoles were designed to run on as well. Since s-video, composite video and the RF switch produce a 480i signal, half of the image would be blanked out at any given time.

Granted, this doesn’t seem to alternate in a flickering pattern between even and odd lines as an interlaced signal would or at least so I would infer from the switch toggle needed to chose between blanking out odd or even rows of pixels. It’s an important part of the effect, as your mind would use the residual data from the last field to extrapolate what the image should look like going into the next. In this way you wouldn’t notice the blank and keeping in mind that pixels are a limitation of the monitor and not the mind, things may’ve theoretically appeared less blocky than they actually were as lines faded together.

Still it’s still a bit more authentic than seeing the whole upscaled image at once, where you’d have two rows of the same colors as either the pixels above or below duplicated with no space between the individual pixels that make up the image. I think your mind would still fill in the blanks to a degree once the mosaic effect kicks in when sitting a reasonable distance away from your monitor as a home based system would assume and more importantly, the colorspace should have greater acuity because you have more black to act as a counterbalance to the bright colors of the game generated footage.

For a more technical understanding of the jargon involved:

On another note:

I’m curious about this too. I think the XRGB throws in scanlines as part of the scaling process which is what allows it to upscale so quickly. Instead of guessing what color every second row should be filled with to make an interlaced signal into a progressive scan one, it just ignores the details and puts in black wherever the image is lacking. This appears to throw them in after the upscaled image has been outputted, giving this the more effect of a post-processing filter that infamously creates input lag. Then again, the process of blanking out every other line is so logically simple that I’m probably just splitting hairs here.

Even if it’s laggy and I’m not necessarily saying it is, it seems like a beautiful device to have for a screen capturing setup though, especially if you have a 15 khz syncing monitor with RGB passthrough… It may allow you to better emulate the experience you wish to share in ways not possible otherwise (while saving you much hassle and a pretty penny on importing the XRGB), as standalone scanline generators are otherwise unavailable.

Game Console>Monitor>BNC-VGA cable>Scaler>Scanline Generator>Screen Capture Device>PC>Hard Drive>Video File>Youtube HD video file.

Or how well would a VGA splitter work if I went from Game Console>Upscaler>Splitter>Monitor|Scaler>Scanline Generator… instead?

Hey,

puh long question, many thoughts, but SLG doesn’t work like the XRGB. SLG doesn’t buffer the frames at all, so there is no chance for lag at all. SLG only job is to care about the scanlines,nothing more.

So a VGA splitter works, too. SLG just outputs the feeded VGA Signal. Only with one addition, the scanlines. Even the intensity control is pure analog technique. Another benefit is that you don’t even need a external PSU. Hope this meets your questions.

I know it’s a bit late, but I’ve added this to the info thread.

thanks a lot :slight_smile: never to late. btw : SLG3000 was mentioned in the current UK gamesTM on page 131

Here are some more pics of current look of SLG. Neanwhile I`ve made a little addition for the SLG3000 for use with low cost scalers. The SYNC Strike

It turns RGB scart to plug and play solution with low cost scalers. The comp video signal from scart will be stripped to comp sync.

This way I`ve dounf a plug and play solution for all RGB Scart consoles.

Take a loot at this example

Playstation 2 with RGB Scart Cable -> Sync Strike -> Low cost Scaler -> SLG3000 -> LCD

result is a fine LCD picture with scanlines :wink:

I’m trying to remember, was the 220 ohm resistor switch they removed from the XRGB line supposed to act a sync stripper or was that something else? Sync Strike looks pretty interesting if it is.

some customers buy the slg3000 even if they own a xrgb. They told me that the scanline performace of slg3000 is much higher : more clear, reducing pixel, more stable

Sync Strike is mainly for use with a scaler if you want to connect your consoles via rgb scart. Additionally it has breakout for every signal

:slight_smile: two sheet acryl case with laser cut outs for Sync Strike :slight_smile:

God i wish i could afford one of these… but i can go buy a CRT tv on craigslist for like 20 bucks… its bulky but way less :frowning:

Sync Strike with Case and cga2vga scaler made it to my shop

So finally such kind of setups are possible :slight_smile:
