So in that video he goes into how he wishes the HDMI connector could be on the back too but the heatsink on the top loader wouldn't allow for the board to be situated back there. He also advises against extending the HDMI connector using individual wires (that'd be a big PITA anyhow). I still wonder if something like a short HDMI extension cable like below would work and give you more flexibility with the position of the external HDMI connection.

With a prebuilt extension you wouldn't need to worry about individual cable length screwing up the video and people modifying the board by trying to desolder the current built in HDMI port. The extension might also be easier to mount vs external screws since you could use your bottle o' gorilla super glue

Can you use a right angle HDMI adapter? Like this: http://www.darkstar.co.nz/argent-...
Or would that interfere also?

It might not cause issues except if the kit is mounted in a top loader or av fami as currently intended it will shoot the cord straight up in the air, not down. Also if used on the front loader, the back of the console will have to be at the edge of a shelf as the female end will be close to flush with the bottom of the console.

I think they may have the incorrect picture on that.  This is probably the one that ThePlague was thinking of:
http://www.monoprice.com/Product?...

but this would be the one that would make it go out the back if the port is upside down:

Actually if the port is upside down the first one would make it go back, right?

I think normally the smaller part is on the bottom. How you described how the 1st link would fit, I would think the 2nd one I linked to would go out the back.

Yeah Jason you'll find stuff like these HDMI angles and extenders cheap on ebay or even for around $2 on monoprice.

Looking at the first video on Jason's youtube channel and looking at the ribbon cables and template they showed the small part of the HDMI port faces up from what I see. The lettering on one side of the ribbon cable helps you figure out orientation.

Is mono price free shipping? I assume not...
The ebay part was $4.50 shipped.
The main board and hdmi port will be upside down in the top loader shell, so yes narrow side on top.
Are there any cables with 90 ends, so this adapter and one connection can be eliminated?

I thought the scoreboard thing was only going to be part of the powerpak2, am I wrong?
 
Not to hijack your thread, but the information provided about the AVS is correct.
It does have the "scoreboard system" and "game genie" built in standard.

They do, but probably cheaper to use the port saver.  The port savers dont cause an issue with anything else, so I would assume they would work fine with this.  Here is a cable I found from a quick search.  There may be cheaper ones:

Link removed as it was wrong cable

One port saver from monoprice for me is $4.44 shipped (so basicly same price as the ebay link).  Cheaper though if you buy more than one or have something else you need.

That cable would route it to the front of the top loader, was there a right angle one?

I don't know the status of the powerpak2 since I am not (yet) on the development team for that product.

Ok I think I know why we are miscommunicating.
The connector is going to come out on the power/reset button side of the top shell.

There's this panel mount 1.5 foot extension on ebay with multi-directional swivel.
http://www.ebay.com/itm/0-5m-1-5F...

It can swivel any which way you want it to.

The swivel worries me, but also not sure it would be needed either, would have to give one a go.

If you could mount it inside the NES connected directly to kevtris's board I'd be less worried about the swivel. If it's internally mounted it should be fairly stationary after installation and not see a lot of repeated bending. But yeah I guess for $4 we'll just have to see... an idea though.

This appears to be for the toploader only; can it be done with the original classic toaster model?

What makes you think that?
In the first minute of the vid I name off the consoles it will go it, the orginal fami is about the only one we're prolly not going to fit in...

From Kevtris:

Here's some example scanline tests from the scanline generator I was working on tonight. I have finished scalers 100% and that is done, so I started on the scanline generators.

http://blog.kevtris.org/blogfiles... ... es/latest/

I ran into a problem which I knew I'd have on 1080p (and PAL modes). That is, each NES scanline requires a non-integer number of scanlines on the HDMI display. Namely at 1080p, each NES scanline needs 4.5 HDMI scanlines.

This means that the height of each subsequent NES scanline alternates 4/5/4/5/4/5 HDMI lines.

To counter this (you can see an example of what this type looks like, see below) I came up with a scan line generator that "free runs" in relation to the NES video, instead of trying to "scanline" each NES line on the HDMI display. The results of this method are in the above /latest/ directory.

There's also a scanline generator that is tied to the actual NES scanlines, but it can look bad (especially on PAL) due to the afore-mentioned problem. Those are here:

http://blog.kevtris.org/blogfiles...

the filename describes how "Deep" the scanline effect is. 0 = no scanlines at all, FF = maximum.
