Anybody has any idea why Atari discontinued 7800 in favour of XEGS? XEGS doesn't really seem to be technically superior (in fact Maria in 7800 seems to be superior to Antic).
I get the point of 8-bit line compatibility but it doesn't seem "logical" to drop (seemingly) better architecture for... worse (when you're competing with Nintendo).
There was no 7800basic BITD. Developers had to deal with whatever dev system and documentation Atari provided, and those often weren't the greatest.
PETSCII robots appears to be running in 160 mode except for the text at the bottom of the screen. I'm specifically talking about the 320 mode being difficult to work with except for developers with a special skillset. That's why the majority of games used 160 mode back then, which looked outdated compared to the competition.
