gameboy:19:12: error: 'mem_init' was not declared in this scope

[seru92]

I have some problem with the mem.cpp, p:\xxxxxxxx\esp32-gameboy-master\gameboy\gameboy.ino: In function 'void setup()':

gameboy:19:12: error: 'mem_init' was not declared in this scope

mem_init();

        ^

I dont bear in that beacause mem_init its a function.
