Re: Possible bug in ZX81x2 ROM ?

Hi, Thanks for this, but no the problem seems to be the ROM code. I have tried a few more hi-res demos and the graphics are corrupted when using this new ROM and I imagine some other programs may suffer also. :o Which programs are affected? It would be good to know, because it would be easier to fin...

Re: SPeccy ON the ZeddY

Hi, Is the Sponzy-Rom in the ZIP ..... ZSOLT's original version? Not exactly: it is different in the "startup" and the "new" section and "DI" instructions have been removed from the entire code.
