I encourage any development of a V9958 graphics card, it would be great.
But... apart from the difference on the ports, the MSX games make an intensive use of libraries on Roms, that would force the conversion coders to add translation Roms on the CPC versions.

Another drawback is the use of different memory paginations on CPC and MSX.

About the Coleco, SG1000/SC3000 conversions to MSX, these machines are pre-MSX, so they share more hardware architecture  than only the Video chip with the MSX.

The selection of the CPC ports for MSX hardware.... that is something that was decided by Prodatron, and I don't know from who he took the idea. The target was to fix the upper byte to &FF on the MSX adapter, and so, every &FFXX port access triggers only the lower byte, &XX, to the cartridge.
I know, as I have said that to him by email/PM or at the Revision event.

What I want to say is, the CPC &FFXX range was selected time before making the real adapter, the Amsdap. It was not a chance.
Sorry, the problem is the "chance" word into my sentence. I mean the luck to have a 16-bit I/O port to allow that.

Well... The Coleco and SG1000 do not have the MSX ROM or paging system too. The CPC already have the same CPU and sound chip, while them have the same CPU and VDP. Anyway, it does not apply to the existing SymbOS programs.

-You are clever....

-Ok, now I understand it. You meant the opportunity to have a spare 256 port range at &FFXX.

-As I have said, I don't want to discourage anybody, only to show objectively the possible problems that may arise.

Yes, the V99x8 are already supported by SymbOS that already made existing applications for the OS runable for a CPC with it.


Maybe it is me, but I do not get it. the V9990 is also supported by SymbOS and is much better compare to the old MSX2 VDP.


The MSX was my machine back then and I don't see the point bringing  the MSX2 VDP to the CPC.. as then you almost basically have a MSX then ;)
And having MSX2 VDP on the CPC does not give you a bunch of games that will work as the CPC as simply it still is different machine. Porting will maybe possible but i think not an easy task.


The v9990 is on the MSX an add- on card. I see it more like the Voodoo card for MSX and now for CPC and ENTERPRISE as well. Running it on different machines would be cool as one release for a game will work on all the machines and no porting is required. Yes there is less software for it but I would hope people will like it and start there own devs for it

I'm not sure why people would want to move backwards from a v9990 to v9958. The v9990 is so superior, already exists/works, and does anyone really believe that people will port MSX2 games too the CPC.
Totally agreed!  :) :) :)

Hopefully Trebmint will release his new QUIGS? The IDE so far is quite impressive and interesting and the language easy to understand. I mean, SymbOS is a very attractive environment, also due to it's very good and deep documentation. But you still need to be an machine code professional to create something. QUIGS could be an approach for Non-Professional/Nerds (like me) to program at least something? Would be cool.
...and after embedding the driver/language support for the V9990 the OPL2 / Adlib sound cards with Pulkomandys Willy adapter or the LambdaSpeak / Midi-Board (with same sound chip) could also be enhanced by Trebmint? :)
...proudly supported Schnapps Demo, Pentomino and NQ-Music-Disc with GFX

There will be a release of Quigs with g9k support very soon (within a week). Yesterday we had the great news that Prodatron has worked out the g9k interrupt, so when I receive the updated symbos I will try to get that included.... this will mean really cool stuff can be done :) Currently I'm adding lots of use cases to the optimizer... I want the Quigs compiler to produce the fastest ever z80 compiled code.
