  1. I have both the prototype #1 for the flashback 2 as well as the Flashback Portable Prototypes. These are some pix. https://u.pcloud.link/publink/show?code=kZR6CIXZhjhT5Nycwyj9fuxOeBm3oXfguqdy
  2. I designed a pretty good cart mod kit to solve the problem of not having enough cartridge slots around from original Ataris.
  3. Thank you VERY much for the diagram! I've been looking for this.
  4. It might be possible to get the signal to 5 volts, but the real issue is that the portable doesn't have the paddle input lines into the controller. Also, i bet the atgames controller is running on 3.3 volts, 5 volts would likely destroy something. I really don't know of any way to move forward without some schematics and seeing the lines needed. I doubt there are analog lines on the portable.
  5. I don't think paddles are ever going to work, atari paddles (potentiometers) are specified for 5 volts. The portable is using 3.8 volts. Assuming the atgames chip is wired for paddles (no reason to believe it is) then the readout of the analog pots would be skewed. The portable is totally digital, paddles are analog. I don't think paddles will ever work on the portable. Asaki, I found the six connections for the joystick (up, down, left, right, fire, ground). The other (+5v, paddle1, paddle2) don't exist on the portable circuit board. I'm happy to post detailed pictures of how I did the mod..
