The idea to combine 2 VDPs (9959 and 9990) is great, please continue with the project, we are waiting, please do not forguet to put more VRAM, (128 to 512k VRAM) much better for videogames using the 2 VDPs.

I hoppe this new MSX can be sell in Europe Big smile

By the way, Yamaha called both the V9978 and the V9990 E-VDP III, so IMHO they really are just one and the same.

It's almost the same chip, as explained on Wikipedia :

http://en.wikipedia.org/wiki/MSX

Quote:

The MSX3 was scheduled for market in 1990. Delays in the development of its VDP—then named V9978 on the pre-release spec sheets—caused Yamaha to miss its time to market deadline.[13] In its place, an improved MSX2+ was released as the MSX Turbo-R; features of the new R800 processor such as DMA and 24-bit addressing were disabled. The VDP was eventually delivered two years after its planned deadline, by which time the market had moved on. In an attempt to reduce its financial loss, Yamaha stripped nearly all V9958 compatibility and marketed the resulting V9990 E-VDP III as a video-chipset for PC VGA graphic cards, with moderate success. Sony also employed the V7040 RGB encoder chip on many other products. MSX-FAN Magazine also mentions the then-impressive power of the V9990, being able to compete with much more expensive hardware such as the Sharp X68000.

The idea of TECNOBYTES is really cool but .. why to start building from roof? I will explain this Smile
I think that we will need to follow the next steps:
1. VOTE FOR THE MSX3 CONFIGURATION. All the MSX users, during a time, decide what MSX3 configuration is better.
2. When this CONFIGURATION will be ok for all the MSX users then ADD IT to the OPENMSX/BLUEMSX emulators.
3. Developers can try to build in this new configuration. Develovers and users could give feedback about it.
4. If the MSX3 configuration it seems ok then produce the new hardware.

I don't know what should be the MSX3 Configuration finally but I assume that would be very closest to have in mix combination the V9959 & V9990 + OPL4 + Z80 compatible with betters specs. In this terms, to create a MSX3 Profile in the OPENMSX or BLUEMSX will be really easy. I think that MSX users should work with emulation to decide the final MSX3 configuration.

Thank you for read my harmful english Smile

Could you call it an msx3 if it is not compatible with tubo r? or more a msx2++ ? Tongue

Do you think that it is an important question the compatibility? I think no really. MSX3 should be a sequel promoted by MSX users. In fact the MSX3 no exists or maybe yes but not like a unique configuration. But it will be easy to mantain MSX compatibility working with both configurations like an emulator. You could start the machine like a MSX, MSX2 MSX2+, MSXTR or MSX3 with CBIOS of course XD

@mars2000you althoug MSX-FAN is the only source, combining a V9958 and a V9990 (superimposed) is simply as close as it gets to what the MSX3 would have been.

What I do understand is that the blueMSX team waits for a larger software database before emulating stuff like this. But something like this "not being MSX" is not a valid argument.

I don't have said that it was not MSX (*), but that it was not fully retro-compatible, and therefore not respecting one important element of the standard. Superimposing V9958 and V9990 will allow indeed to bypasss this lack of retro-compatibility. But the main question is still : how much software ?

(*) I guess my words "beyond and outside the MSX compatibility" were a little too emotional Wink

Not enough.. but at least not nothing Tongue. More availability of the hardware might make more people interested in making v9990 stuff.

It's a bit of the chicken and the egg, isn't it?

- More/better emulation of V9990 opens it up to a vastly larger audience
- More V9990 hardware does the same, ironically on a somewhat smaller scale
- A larger audience makes the chip more interesting to developers
- More developers means more software, means more interest in the emulation and hardware
ad infinitum

All I can say is this: I hereby pledge to follow up No Pressure with something for the V9990. That's something, isn't it? Smile

I had been thinking about making something for v9990 after im done with my current project, but indeed more active ppl with a v9990 or just more activity (more ppl making stuff for it) would make me put it higher on my priority list Cool
