AKAIK the hardware sprites are much simpler to implement. I don't know Lynx, but the blitter like you described needs uncomparably faster hardware than a set of hardware sprites.

I'm inclined to think the Atari Lynx is the pinnacle of '80s graphics chipsets: just a frame buffer and a scaling blitter. No need for all the special-case sprites/backgrounds nonsense.

In an ideal world you could have :

32/8 full colour hardware sprites ...16x16 or 8x8 ? with sprite collision detection ?
Hardware scroll vertical/horizontal
Increase in Colour palette
Hardware line interrupts (programmable) to switch palette at a fixed number of scan lines ? No need for CPU intervention.

Even a second Video processor to give superposition, Superimposed video. This could be something like a V9938/V9958. though this obviously would mean quite a bit of extra circuitry, but the resulting graphics would be superb, probably surpassing a Commodore AMIGA.

Though this all boils down to someone with the time, brains and means to make it happen !

I think hardware sprites would be great, increase in colour palette would be beneficial as long as more colours on screen at once was introduced but given the size of the screen as standard is 24k more colours on screen would mean more memory unless line interrupts were used then this would have speed issues on the cpu, so how could this be used?

I agree. The original (crowdfunding) plans for the "new" Golden ASIC's involved hardware sprites and palette expansion to 4096, which is enough for most needs, and this as upgrade for the original SAM 1.

I think hardware sprites would be more beneficial than so many colors. If I look to old game cabinets from 80’s, many of them have got excellent games with simple slow CPU’s... but always with hardware sprites=
