Super Cobra Arcade

Recommended Posts

At least on my monitor both look better with phosphor enabled (blend = 50).

 

And I cannot see any issue with scrolling. What have you been noticing here?

It's just a personal preference, I agree it should be set to ON for Stella properties. For me, the PF scrolling bleeds too much in Stella with phosphor on, but the reduced flicker in the sprites is better so it's a wash. I play it only on real hardware so either way doesn't matter to me, I just want it to be consistent with Scramble (or we change both to phosphor on, I can't recall what it was set to originally).

Thanks for the ROM and thanks again for signing my copy at PRGE.

You're welcome Steve - it was nice to meet you! My brother and I are already blocking off the weekend in 2018 to return to Portland; hopefully I'll have a couple new games ready to go by then! :)

A great way to say thanks is to add your reviews. Same goes for other games ;)

I agree with Darrell... besides having someone actually like the game enough to buy it, then next best thing is to read an open an honest review. While you're writing one up for Super Cobra Arcade, make sure to drop one for the even more impressive Draconian! I got the chance to play it at PRGE and was completely blown away by how awesome it was, especially the in-game speech! Which reminds me, I need to pre-order my own copy and prepare to write my own review... ;)

IMO an open and honest(!) is even worth more than a sale*. For more discussion see here.

 

*People buy a lot of crap these days.

So impressive! I'm still a beginner 6502 VCS coder; I can't image how y'all can manage this! Do you use DPC+, custom ARM code, or what?

DPC+ is close :) The game uses CDF, which is even more efficient at offloading parts of the game to the ARM.

Thanks! Yup, as DH said, it's CDF which is basically a more feature-rich version of DPC+, which of itself is an extension of the DPC chip developed by David Crane and Activision back in the early 80's for Pitfall! 2.

 

As with all 2600 games, you are still bound by the TIA chip and the kernels are all written in 6502 assembly. The big advantage of CDF/DPC+ is the extra ROM, extra RAM, fast-fetch (which allows you to dynamically update a TIA register in 5 cycles), and of course the 70Mhz ARM processor. I call this twice per frame, once during VBLANK to set up the current frame (graphics) and once during overscan (this is where I do most of the collision detection, game logic, sound, etc). DPC+ also adds 3-voice digitized music and sample support. CDF adds, among other things, the ability to do a dynamic JMP in 3 cycles (vs. 10 in DPC). The ARM code is also written in C which (at least for me) is easier to program game logic with.

Wow! This game is incredible! Thank you very much for making this available for free. It's like an early Christmas present.

 

On a side note, I am constantly amazed by the incredibly high quality of many Atari 2600 homebrew games. They're as good, if not better, than most of the games we had back in the day.

This game is amazing but hard! I got all the way to the end of scramble without dying, but couldnt get to the second section in Super Cobra.

The difficulty (on Advanced) is in keeping with the arcade game, which is brutal. But the Novice and Standard modes are more forgiving. Just to make the YouTube video I had to use a ton of Save States. I don't think I've yet captured the Booty on Advanced, even using all of my Continues. But I am improving. And as a side effect, I've gotten a lot better at Scramble. ;)

Scramble still kicks my butt every time. Just like in the arcade original, I can't seem to negotiate those quick 90-degree turns. I think it gets harder each time now since the passages have gotten narrower due to the hundreds of burned-out ship hulls embedded in the walls.

Yeah that last level is where I lost it. The rest of the game is easy though.

My package arrived last week.

It's just unreal, that the game is running on an Atari 2600.

My mind is blown, and so are my friends :D

Love it!

 

Amazing job!

Still loving the game & will be getting the cart soon. Wish I could take it on the go but sadly, doesn't work it the Atari emulator 2600.emu or Retroarch for Android.

Just wanted to shout out this game is awesome. My fiance made me wait until after my january birthday to get it since I had draconian for Christmas. If you liked Scramble, you'll love this one.

 

Made it all the way to the base before I lost all my continues. Did not collect the booty, yet... :P

 

Anyway this game is fantastic! :grin: :thumbsup:
