BTW Atari Lynx was 6502 game console.
Maybe it is Public Domain / OpenSource:
"On May 14, 1999, Hasbro, which would continue to hold on to the Atari properties until selling off Hasbro Interactive to Infogrames in 2001, released into the public domain all the rights relating to the Atari Jaguar, declaring it an open platform; the Atari Lynx, through internet theories, may have also entered the public domain at the same time as the Jaguar, but this is clearly disputed.

Lynx 3D capabilities:
My ideal 6502 game console will be Atari Lynx FPGA with better specs (more MHz, colors, ram) and SD card and probably pcb mountable into Gameboy case(there are new still produced). There are tools like ASM, sound editor, graphics, emulator also games. But I am Atari fan ;). Anyways it will be amazing game handheld.
