In the past, the time of the release of the first version of GRAFX9000, I've made some test with the superimpose capability of the GRAFX9000, just forget about the clock synchronisation explanned by Koen van Hartingsveldt and Peter Burkhard, there is an other problem. Since the superimpose of the GRAFX9000 use pulse for line and frame synchronisation instead of using a VCO and a PLL (Phase Locked Loop) to ajust the clock oscilator frequency input. The result when you want to use the line interupt capability of the V990 is that you computer hang! I noticed that when I wanted to add a background on a P1 mode multi layer scrolling. Then only way to make the multi scrolling work again was to switch off the superimpose mode. Martial. MSX Mailinglist.

It's name : "Mega 32X" It's an multi processor (SMP) upgrade for SEGA Mega Drive ... I think that most people here even heard about it . It contains 2 Hitachi SuperH-2 processors , an new VDP , superimposing hardware and more work RAM for the SEGA Megadrive. It was a pretty complex machine , the developers ran away when they saw it ... Most games for it are from SEGA. It does use the V9938-like VDP of the Megadrive to generate simpler backgrounds while the main VDP (inside the 32X) does the hard work (32k colors). This thing , I would not doubt if someone says it uses a V9990 or an custom version of it as VDP ... Cya MSXers ... MSX Mailinglist.

Nice Gfx9000 idea...
The Gfx9000 can superimpose the image over an incoming signal, can't it??? If that's so then you can create a game/program showing 3-layers!!! The background doesn't move or only moves up and down, which is the v9938 screen. If it's a bit vague, that doesn't matter. It's just a background. The second and third layer are the layers of the P1-mode... That way you can create a very, very nice multilayer platform-game!!! ~Grauw "wants a Gfx9000..." -- >< email me: [EMAIL PROTECTED] or ICQ: 10196372 visit the Datax homepage at http://datax.cjb.net/ MSX fair Bussum / MSX Marathon homepage: http://msxfair.cjb.net/ >< MSX Mailinglist.
