@reidrac if you need tests on real hardware: i have a CGA Redux card.

@root42 that would be cool (at some point). Thanks!

@reidrac that palette brings memories.

@rogersm @reidrac yeah, I was just thinking that CGA looks way more nostalgic than it has any right to lol

reidrac, 9 months ago

@HunterZ @rogersm yep! I'm really enjoying the mood (the coding is fiddly though).

@reidrac @rogersm yeah, I installed Watcom in DOSBox a while back and rolled some C++ code from scratch to draw CGA for fun. Can't find my posts now, but I remember the memory interlacing being a pain to deal with for sure.

@HunterZ @rogersm once I understood the offset, isn't that bad.

What is bringing me flashes in ZX Spectrum is the 4 pixels encoded on a byte. To do 1 pixel movement it requires preshifting sprites if you want to go fast, or a lot of manual written asm 😬

@reidrac As a Speccy coder you won't be that phased by the relatively straightforward CGA interlace I guess!

@cyningstan could be easier! 😂
