It's me once again. Hello!
Like the title said, is there a way i can connect external memory to an atmega2560? If there is, can someone tell me how?

Yes, there is a way. Here is: Arduino Mega 512K SRAM in shield format | Andys Workshop.
And also: 512Kb SRAM expansion for the Arduino Mega (design) | Andys Workshop.

Looks like they are making them again! I bought one years ago and they stopped making them for a whole, which made me think they won't be making anymore. So I never go around to use mine. The first 64KB requires no work at all.
