I use the 4x FBX settings for Genesis, the 5x FBX for SG-1000, SMS, and Colecovision, and the recommended larger screen settings for Game Gear. I revert back to 4x for codemasters SMS games.

Anyone notice odd scanlines with the latest update (7.5)? Decided to dial in 720p instead of 1080p and enable scanlines. They are weird. It's like it changes the hue of every other line? So something will be light brown, scan line, dark brown, scan line, light brown, scan line, etc. This happens with both normal and hybrid scanlines checked.

I just loaded up Shining in the Darkness to test since that's what I've been playing lately and it's really weird. Color goes back to normal once you disable scanlines or if you go to 1080p. I am using the following 720p settings from FBX:

-- FirebrandX 720p, square for 320
* set horizontal pos=27, vertical pos=39
320: 1020x720 disable HV
256: 931x720 enable H, disable V

Loaded up sonic 2 as well and same thing.

I saw this earlier and it looks really, really cool. With this I could just leave it in my Mega Sg and not have to have the CD attachment hooked up to it. I'm going to wait a while until I get one though just to see if people find any issues with it.

They indeed tried to fix the scanlines, They told me the next Super NT firmware will feature the same Scanline solution as the Mega SG update.
At first site they appear correct at my tv, i will check some more.

kind regards,
Ronald

The new scanline engine is made for 1080p output, on which is actually looks pretty good.

It's not really suited for 720p output though. This more or less results in blind adjusting until it looks somehow OK. On 720p the sliders work against each other.

Also 480p is still or even more broken on the new FW than it was before. Before it was possible to get proper (2x horizontal) 480p output in simple mode, just the advanced mode was broken. Now both are disfunctional. In simple mode the picture is missing a good portion on the right edge.

There might not be too many people out there to use 480p, but it's great for use on ED sets and it's a pity that bugs like these are overlooked (despite being reported).
