| Oct 17, 2015 at 16:31 | comment | added | Foxcat385 | It must be ATMEGA2560 because of the pin count and XMEM for the display. My project is to make an 8-bit AVR game console with most RAM as possible and a fast LCD. It's something like those NTSC projects, but mine is a handheld console. If I have to, I can work in full ASM. | |
