I have controllers with a bypass adapter built in. Basically, you plug this arcade style joystick into the CV's controller port and the wire has a Y in it with a place to plug in your CV controller. They were mass manufactured but I never saw them at retail BITD. I got mine at a surplus store in the 90's. It was called the Prostick III. (The buttons are on the front BTW)
Monkey, this is a brilliant idea! I'm going to either find cables or a way to do my own pass through mod when I get my Coleco stuff out again. Thanks for posting this! BTW, I like that your controller almost looks like it says either Prosuck III or Prosack III depending on how you look at it.
I'm not expert on INTV, but in the past two years I've had a interest and got 4 systems(I A/V modded 2 so far), handful of carts, the DS release of Intellivision Lives and a the Flashback. The best thing I feel is good on the FB is the pads. Regardless if you love or hate the disc controller, it is truth. Finding a perfect working 1978 INTV pad that works is laughable...with the FB, you get NEW controllers. I have no issue with the EMU that is running the ROMs, and they are the real ROMs from what I understand (unlike the NoaC, plug-in TV pads that came out earlier). If you have any interest in learning more about Intellivision, the Flashback is a cheap, easy start.
PS: I can't play any of more complicated games yet. I stick with Thunder Castle, Night Stalker, Astro Smash, Shark Shark and my current fav: Chip Shot Golf! (shout outs to Jodi for the hook up!). Eventually I'll read the manuals to figure them out.
I feel like it's still a better option than the Intellivision Lives collections, right? Only because I am unsure how they handle the touchpad issue. I could imagine you could pop up a virtual pad in the hud, perhaps even with full card graphics for every included game, but I dunno! If that were the case, maybe the PS2 version would be nice to pick up. I love the Activision 2600 collection. But if I see the Intellivision Flashback for cheap enough, I will undoubtedly go for it.
