I just discovered this project yesterday. No idea how I could have missed it
Well, I've deliberately avoided creating too much hype until everything is implemented on a single board and working well enough.
I think it looks extremely promising already! The Gunstar Heroes shot already looks quite a bit better than what the Framemeister can produce, due to it's RGB444 > YUV422 subsampling.
The scanlines look great as well, but they are a bit too dark for my taste. Will the user be able to adjust the brightness of these?
Yes, you can freely set the strength as shown
in the controls of the prototype.
I'm also very glad that you decided to add 720p as all TVs I've owned scales this better than 480p. Panasonic TVs are especially retarded when it comes to 480p as it forces overscan which can't be disabled.
As I understand there will be no framerate conversion with this device? I wonder if this won't cause trouble with a lot of TVs since most retro consoles are a bit off the standard 59.94Hz. The Neo Geo CD (and probably AES too) comes to mind, because it runs at 59.4Hz according to the Framemeister. And the MVS as well as other arcade systems running at 59.1Hz or even weirder refresh-rates will probably not work at all?
In my experience a Panasonic plasma (haven't owned any of their LCD models) is much more tolerable to obscure refresh-rates than other TVs.
Using the Neo Geo CD with my Framemeister and a locked sync output, the Panasonics would display no stuttering at all, where there was some on the other TVs I tested.
You've understood correctly, there is no framerate conversion so this is not a system for everyone. As you said, Panasonics display slightly non-standard refresh rates without issues, but unfortunately they are not as tolerant with horizontal/vertical area. For example, my VT30 doesn't accept the 720p generated by the linetripler as it has more blanking lines than the CEA 720p mode, so 480p is the only option with that TV.
The tested TVs were Panasonic S20, Panasonic ST50, Samsung E6500 (plasma) and a Sony W905A.
If this mod
can be modified to OC every system to proper standards then that's fine by me! I'd rather have a ~1% increase in speed (in most cases even less) than stutter. And I doubt anyone could ever tell the difference. It's not like the ~17% difference between 50Hz and 60Hz :p
This wasn't meant as a criticism, but merely a heads up that some systems might not work as well on some of the more strict TVs
Yeah, the reality is that some console/TV -combinations just won't give good results by default, unless you apply mods like that.
