  My Atari 2600 emulator written in Python failure version 1	4500000

• Python is 2250 times faster than my failed emulator. My emulator could reach 113 FPS if it runs 2250 times faster and the Atari 2600 needs only 60 FPS, sounds good.

Reviews

• The final version is only 4 FPS at last, the reality is brutal.
