>yes, game logic looks like Atari JetFighter but PCB is not some Atari clone. it have CPU >(i8080 clone) so it can be emulated. "..here we have CPU-controlled 4x sprite (2x >airplanes and 2x theirs projectiles), one line of text (game score, insert coin text, >etc) and discrete sound."
Good to know that Istrebiteli has a chance to be supported sooner compared to Atari Jet Fighter. I just noticed Istrebiteli has its own source file. Good luck getting the game to a working state.
As for discrete audio, that will be a chore for having to document each of the audio sound effects to determine which adjustable pot each sound effect goes to since some pots might adjust audio frequency pitch (high or low) while other pots control individual volume output of each sound effect. I don't remember game name, but one of the Midway 8080 games had 7 to 8 different sound effects with each adjustable pot able to control volume output or frequency pitch. Derrick Renaud and Zsolt Vasvari were scratching the surface when they did their discrete audio work with Midway 8080 hardware games back in 2007.
Hard to tell if Istrebiteli uses a blue color transparent (acetate) sheet taped to backside of the plexiglass bezel. To me, the photo looks like there is one, but when watching videoclip, it doesn't look like there is a blue overlay piece. If the upright cab (bezel) does use an overlay piece, fortunately the color can be handled with an internal artwork layout file.
