Change CPU cycles per frame...again

Currently it is timed by scanlines. But I think this is wrong.

The keyword here is "normally" suggesting that it can take more or less, and in Mode 1, it only takes a few cycles.

And the Realboy Blog Post states: "Because the Game Boy’s CPU is clocked at 4194304hz (that is, 4194304 cycles per second)". 4194304 / 60 = 69905.06666666667 cycles per frame.

Which matches up with codeslinger's reasoning: "According to game pan docs site the amount of clock cycles the gameboy can exectue every second is 4194304 which means that if each frame we update the emulator 60 times a second the each frame will execute 69905(4194304/60) clock cycles. This will ensure the emulator is run at the correct speed".

Actually cycles are right, just need to fix comment. Gameboy doesn't run at 60fps, runs at like 59.73 fps

Oh this is already fixed 😂
