Previous Atari video games had graphics glitches due to CPU bottlenecks
Now that we all know how the graphics labored on the Nintendo Leisure System and Commodore sixty four, The iBookGuy needs to inform us all about how the Apple II and Atari 2600 obtained their groove on. Within the newest video he says that the Apple II truly used two totally different methods for producing visuals relying on whether or not you had a monochrome or shade monitor unit. And the rationale white textual content on a black background seems virtually rainbow-like in nature on colour machines has to do with pixel placement. For instance, blue and inexperienced being subsequent to one another on display requires good alignment lest you need white mages to have spots of the previous bleeding into them.
For CPU-pushed graphics (fairly than these from a devoted graphics processor) like what was discovered on basic Atari methods, the left-most portion of the display had black strains as a result of there wasn’t sufficient time for the processor to run the sport code and draw the display concurrently. You possibly can even see it within the GIF up above!
Like this YouTuber’s earlier video, the knowledge right here is tremendous straightforward to comply with. The iBookGuy says he’ll maintain the collection going with movies about how basic recreation music and sound results labored. Clips targeted on VGA graphics could possibly be coming if there’s sufficient name for it — you possibly can, ahem, shade us . Sorry.
