converting a picture into patterns and namespace
Based on some converters i did for other computer/console systems (msx, zx-spectrum, c64, samcoupe, etc.), and in a need of trying to understand a bit more of the NES hardware, and trying to get the most of a static display, without lacing or synchronized line interruptions (like from some NES demos), i started to develop a converter for that - it's still very incomplete, since it's still not very efficient on choosing the most unique and repeated 256 cells from 960, and it doesn't saves yet the result as patterns (i still don't know well the limitations) and namespace files.

thank you, but the code is still very embrionary and plenty of mistakes - for example, i didn't know how the colours and attributes works on NES when coded this... :| - but having a better algorythm can extract and combine the 4 groups of 13 colours (3 in each and 1 shared from all), i think the code will be hugelly more efficient...

This is cool. Kishan has been working on something similar. I think he'll post the code soon.
