Whatever it is it looks really cool! Hope we get to play with it here in Europe…

My only doubt is would it be totally backwards compatible with standard MSX VDPs?. If so, maybe it could generate a single video output unlike the GFX9K.

i don't think there's even an intention for any compatibility given that the core VDP chip of this cartridge is very different from MSX VDP at all

So much closer to a GFX9K than to a F18A then?. I would find nicer to keep some compatibilty degree with older modes, I like better the F18A approach. Let's see...

Hi! I'm here Smile

The XGA project is a part of my big picture project X3 and it's a graphic extension. I started this project to replace old-beloved VDPs with modern better ones. Our MSX system is good enough but must be upgraded to handle large files, high-quality audio, sound and graphic data. The keywords on this project are: "functional improvement", "easy programming", "connectivity to modern displays".

Here are some answers of your questions;

XGA is
an implementation based on FPGA
not compatible to V99xx

If you watched my videos and checked "https://blog.daum.net/jsfx" carefully, you can guess the specification and capability. Since XGA is still under development, the final specification is not fixed.

If you have another question, many channels are open including MSX resource center.

I am very very interested in it. Will the XGA have a possibility to overlay (superimpose) the graphics over the visuals of a V99XX?

And the tower defense type game you showed in one of your video's that was made for it; is it a finished game or will it be worked on later to finish it?

Can you tell us what the big picture projext X3 is?

Yes and No. Because of timing problem, V99XX's output is not clean at this moment. I'll try more approaches to resolve it later. I'm not sure it can be solved perfectly.

I made it as a bench marking program. This kind of games are hard to be realized in current MSX hardware system. The demo runs on OCM with XGA and another hardware acceleration cartridge^^
Do you want make one? Hope to share my hardware in near future...

You know what it is. All MSX users dream it. Just with different colors^^

What a smart you are.
But now it must be JS-X3 Tongue
