When the processor tries to read the game program from the empty cartridge slot, it ends up reading random bytes from the data bus. Its like a random program commanding the video and audio hardware!
Yes... A real Atari does the same thing! That's what the processor and the other chips produce when the machine is started with no ROM to be executed.
I tried to implement the emulation at the hardware component level as accurately as I could. It happened spontaneously!
Thats an amazing observation mjn!!!
I knew a little about the Nyquist frequency, but I didn't really hear much aliasing during development. Surely that is a good point to improve!
Thanks.
Please, when possible, update to the latest version (0.92), and always check for updates.
A "Powered by Javatari" crediting on your page with a link to the emulator website would also be great! ;-)
