The problem is that there are no off the shelf chips that feel anything like the video chips of the late 8bit or 16bit eras.
You can do a bitmapped or character displays with just a bit discrete logic.
The graphics chips that do exist these days are all focused at driving LCD touchscreen interfaces with the cheapest microcontroller possible. They communicate over quad spi (not an interface that works with classic 8bit CPUs) and support 24bit color with complex modern drawing primitives like "draw line, draw box, draw circle and decode jpeg".
Sadly, if you want a sprite and tilemap video chip for your modern 8bit computer without resorting to old stock, an FPGA is about your only option.
Which isn't that inaccurate. Most video chips of that era were custom designs themselves, and FPGAs can be though of as just a simple way to achieve custom chip design on a hobbyist budget.
