Small snippet to make the AY scream a bit
#20

Even though INK or PAPER might make nonsense in other platforms, new features can be added just by using function calls and subs (this is what C does, in fact).

yes, NES display is really different (and a bit confusing for all people used to code on known 8bit computers) - bitmap patterns (256 8x8 patterns, taking 4kb, used a bit like msx1 in text mode) are 2bit (instead of 1bit from zx-spectrum, msx1, etc.) - 4 groups of 4 colours, which colour '0' (border colour) of each is always the same - resulting on 13 colours - attribute are, for choosing these groups, is 16x15 as displayed (32x32 as whole playfield) - and the palette used on hardware sprites are another 12 colours, which colour '0' is for transparent (from the same 64 - which seems based on yuv, not rgb (like 2 bit for each primary) )
