hello im new to this emulator thing and i wana play legend of zelda but when i start the game up it says press start now ive started the game before and ran perfect (besides the frame rate) and i went into fullscreen and couldnt get back out cuz i didnt know what button it was to exit fullscreen (i know now) so i command + Q-ed to close it then i reopened it and when i went to press enter (return for mac) nothing happened it and it ran smoothly its just i couldnt get past the enter screen (also my frame rate goes really slow out side then when i go inside some house it go to 100 fps then im like flash and i speed around everywhere cuz my fps is so good inside) any ideas on how to fix these 2 problems? thanks.
