  1. We had some complications, but we just produced a first batch of plates.
  2. Opa, não programo em ASM, talvez um dia, a implementação do F8 foi apenas um pico de inspiração! rsrsrs Abs
  3. I found a simple way to join 4k and 8k games with a little extra hardware and using the same program. Thank you very much for your help, DrWho198, Blinky, and all who collaborate with this forum!
  4. I found a mistake in the scheme I published a few days ago. I forgot to represent line A0 on pin 2 of IC 74LS74.
  5. I think I helped with my last test! I found a simple way to join 4k and 8k games with a little extra hardware and using the same program.
  6. Yesssss! 4K and 8K games together! https://www.youtube.com/watch?v=rrXZi2l3DFw&feature=em-upload_owner
  7. I did some studies and tests, I was able to make the cartridge with menu having games of 8K and 4K. The scheme is not completely adjusted, I used a V29C51002T instead of the emprom to speed up the tests. arqsaida_old.bin
  8. Alex_79 if I want to make a cartridge using 8K games, the procedure will be the same?
  9. Alex 79, congratulations! I tested the atari! All games work perfectly! Including the reset button!
  10. Alex_79, I did not know the new version of Stella, now worked well, later will test the Atari! Thank you!
  11. Added the safenet.bin, the latest games (Keystone, pacman 4k, qbert) do not work, the reactor jumps to the River Raid.
