hap, yeah that. And sorry, I can't remember you brought it up, but sometimes it takes a bit more than bringing things up to get people interested. There is A LOT out there, on the net...

No problem manuel, I was just trying to point out a similar thing to what you just said, that information sometimes goes by unnoticed.

If you're really convinced it's cool, talk about ideas on our IRC channel, or post an item in our tracker system or on our openmsx-devel mailinglist. That at least makes sure we'll see it. Posting in a "random" forum makes it less likely.

You mean the picture on the bottom left? It's the NES, that specific artifact doesn't apply to the TMS9918. Download the libraries for detailed information, they're well documented.
Well... It definately happens at least with Japanese PX-7 (TMS-9929A)

It's possible it's caused by slight differences between the Japanese 9929 and the American 9918, another possibility is that CRT scanline gaps might give the illusion of serrated edges.

*edit* Just to be sure, you might want to inform blargg about it, so he can look into it. His email address is at his homepage.

Come on... trust me... I can see the difference of serrated edges and CRT scanlines

BTW as Japanese PX-7 is 60Hz machine the video chip must be TMS-9928/A (I just looked the video chip from MSX-FAQ)

Although I've seen tons of different european MSX-machines the PX-7 is only Japanese MSX-computer that I've seen connected to Japanese monitor with composite. With european MSX's I have not seen anything like this to happen. IIRC this artifact does not happen in PX-7 if you connect trough RGB, but I'm not sure about this. How ever I'm sure that I've seen this artifact as it really amazed me first time as I had not ever seen anything like that before.

Maybe some Japanese reader could comment this issue?
