Surely the Lynx is technically more advanced than the C64.
Many Lynx games look bad because of the low frame rate today in emulators or modded LCD screens.
But for the original displays there was no reason to go beyond 20 or even 15 FPS.
A downside of the software sprites is that you can not easily get good framerates when you have unscaled full screen graphics.
There is MUCH left that could be done for/on the Lynx. I find it awesome
I think only the Gameboy Advance surpassed the Lynx (by far) almost 10 years later in terms of handhelds.
A memory mapped cartridge access (that SUSY could adress) would have been a (literal) gamechanger.
The SUSY Math isnt really helpful since they are not particularly fast. Certainly not the division.
Colors + handling are great in my opinion.
The Lynx is a unique step inbetween the C64 and the PC-Engine.
Both among the very last 8bit systems.
