Re: Chroma 81 - SCART and Colour interface for the ZX81
How did you make it on the first attempt ??? I'm getting crazy :/ ...by the way that driver is a fantastic piece of code: I'm still trying to figure out how it works :oops: My 136 pixel driver will probably never work well, but it taught me a couple of intersting things about the emulators features ...

Re: Chroma 81 - SCART and Colour interface for the ZX81
I'm afraid I've been too confident .. the R register does not stay the same for long enough so the picture gets garbled. Also the WRX mod could not react as I expected when I poke on the ghosted locations. Is it possible to run my test program on the real hardware ? The nasty background colors are p...

Re: Chroma 81 - SCART and Colour interface for the ZX81
There is still one detail I did not get fully. The 32 bytes being "executed" by the WRX driver are just a dummy line. I suppose we also need its ghost copy to put the attributes in ? If so also the 8x8 attribute stuff would require more than 6144+2*768. By "more than" I'm referring to the fact that ...
Re: JSZeddy
Well, having coloured WRX helps for 'wall' only, DStar runs well in UDG mode too.
Probably some color-cycling effect in mode 0 would have been better, but this tweak in mode 1 is a bit easier..

Re: Chroma 81 - SCART and Colour interface for the ZX81
Probably it is something I should have understood myself reading your posts and webpage carefully, but.. is there a way to use colors in WRX graphics mode ?

Re: DarkStar 2
Uh well.. it is a feature but it makes little sense on the "vanilla version", if you don't previously load a redefined font. Check the previous posts and get the UDG version to see some better result, AFAIR it starts in QuickSilva mode, then you can choose the right bank with the number keys. The Dk...

Re: Rom hex file help
Hello !
I think you can get the rom yourself via the debug procedure I described. It is much easier than it looks.
Use the ROM version you prefer, patch it and test it on EightyOne first.
It is the only possible shot I'm able to suggest (at the moment), and I think it is worth to try.
