I have just added support for scolorq and now am using ciede2000 for some nearest color calculations (slows down dithering but increase quality by abit) The image on the left is the dithered image that scolorq outputs. The image on the right uses the same palette but is dithered with the standard fl...

That idea of supporting a common format is good idea as it saves lots of time on writing tools however I think it would be a good idea to remove the pcm samples from the IT module since this driver appears replaces the samples with psg and fm voice so there is no need to store the unused samples oth...

It was my main goal when I bought a teensy : LOW cost USB writeable cart You approach is really interesting since it uses few components ... If you could give us more details (for totally newb), it would be great ... I could host files for a tutorial if you need to... My programmer is made to progr...

I tried to use Retro Graphics Toolkit to compare but I can't get it to work (either it has some bugs or I'm bad, I'll try again soon). Could you please explain why you can't get it to work so that I can fix it for you? Also here is a table based on real hardware that would be better for your script...

Can it be modified to any count? void generate_optimal_palette(Fl_Widget*,void * row) { /* This function is one of the more importan features of the program This will look at the tile map and based on that find an optimal palette */ uint8_...

Yes, it won't break an image into 16-colors tiles. It may be possible to write a script that combines several imagemagick commands to do that. Imagemagick may not be the best tool to do such a thing.
That is why there is Retro Graphics Toolkit.

If you are only interested in the pcb... design it yourself! It's as easy as connecting most pins of the rom/eprom with the cartridge connector. Then send the design to a qualified shop. That is what I am doing and in fact I made a sst39sf040 programmer using an arduino uno and 3 74hc595. The sst39...

I do not understand why Nemesis is being criticized for doing necessary precautions. Also it is not like Nemesis is doing something unusual even the FSF requires a CLA. Also these legal precautions not only give Nemesis peace of mind but also the contributor so if anything it makes it easier for the...

Since you are using an AVR you can generate up F_CPU/2 with PWM I believe the teensy has a 16mhz clock so you can generate an 8mhz clock which is perfect for the ym2612. This should save abit on components.

I have a new build system that allows me to build the windows...
