The colour problems you see are produced because bias is not totally implemented.

I hope the next version will cover all video modes. It was funny to see the "gracha" mode working.

Also, Dave sound needs some effort on interrupts, to work with sampled sound, and to lower the playing rate, that is double as fast now.

For me, all this work seems incredible, when one thinks that this is not a program emulating the EP, but a lot of discrete components(inside a programmable chip) making the same things that the custom chips.

So, in a future it could be possible to clone Nick and Dave following the VHDL code.

Sorry, i wanted to logon yesterday, but forgot, today i watched it
4x6 internal DAC did not work in DTM player, because it uses speciality of Dave, it initiailize the 4 channels to be able to play samples on 4 channels without loosing volume level, without this special initialization the volume is lower, so until if DAVE is not fully complete in FPGA 4x5 bit DAC can be used id DTM player.

Just now noticed the word "Elképesztő" on the advertisement, that's amazing !

I did notice the forum's logo there I'm always amazed by how many EP fans there are all over the world. I'm happy our forum could help these people to reach each other.
It is also great privilege to see awesome projects to born and progress like this one.

Keep up the good work!

I've been improving Nick implementation

Some screnshots from Geco's Fred


4 colours
ATTR mode
16 colours

The random lines on the left are caused by my image capture card...

Looks better and better
I think something is wrong in the palette, or with color assignment, i saw your code, and that seems to be good, but in Fred i see also some wrong colours, for exampla the bottom of col16 and attribute game screen should be yellow. (it seems to be bias 9 instead of bias 11)
in col16 picture bias 0 gray is missing from the brick, bottom of torch is bias 4 blue instead of bias 9.
So i think the colour assigment has problems from bias, i think bricks at Bricky screen uses also mainly bias colours.

I sent a mail to you about 1-2 weeks ago, about some other links, just before my mail about 4 colour character mode, did not you get it?

I just can't see what I'm doing wrong, why sometimes the colors look good and other times they don't.

Yes, it is strange, because there are programs which have quite good colour assignment, and some which strange, ex Exolon CPC conversion, and from the pictures what you posted below, i see that there is a problem with bias colours, i do not see too much problem on Fred main screen, but the attribute picture use few bias colours.
