Intellivision - Battlestar Galactica: Space Battle

[n5x]

I always wondered if it would be possible to convert space battle back to battlestar galatica as it was intended?

[1980gamer]

Wait, would it be.....

Super Pro Battle Star Galactica

or

Battle Star Galatica: Space Battle

or

Galactica

Super Pro Space Battle

or

Ms. Space Battle?

No matter how you slice it, I loved this game as a kid and even tried to make in on the TI99/4A... Might be available in the forums... can't remember if I put it up here?

But I'd love to see this updated.

Maybe a simple mode: TV Pix style for little kids. NOT sharp shot. Single cannon and the additional graphics.

 

Found the TI version I was working on: http://atariage.com/forums/topic/210894-space-battle-based-on-the-intellivision-version/?hl=%2Bspace+%2Bbattle&do=findComment&comment=2743698

I should finish this game!

Just need some better math skills! Making the enemy ships rollover/loop is not very easy... for me! I have the graphics done at least.

hey rev, i can scan this in if you need an autographed pic for your cover.

Happy to say I got to meet Dirk Benedict at Galacticon 3. Galacticon 4 will be this year in Seattle I believe.

 

I'm a bit of a fan of the classic Battlestar Galactica.

 

About Space Battle, I think this would be a good lesson in decompiling, modifying, and recompiling a game.

 

Can anyone please give any pointers on how to do that?

 

Really, I think all you would need to do is make it where the opening screen says "Battlestar Galactica" instead of "Space Battle" and you'd be just about set.

 

First off, the Cylon ships are great. I mean you see those things flying, spinning, and the detail is actually quite amazing.

 

I like the look and feel of the game as it is, but since I loved the vipers in that game, with a bit more tweaking, I would add the following effects...

 

1) I would give the background a moving starfield. Make it where the starfield flies by in relation to the cursor. Give more of a Viper cockpit effect.

 

2) Change the firing sound to match the blaster sound effects on the show.

 

But no, the game is already amazingly a Battlestar Galactica game. I am proud that Intellivision/Mattel was trying to make a game based on the show.

Well, I tried a hex editor to change the opening title screen from "Space Battle" to like "Battlestar" but that broked the rom file.

 

Hey, it worked on the Atari computer. I got games to say all sorts of interesting things. Even once modified Star Raiders to be an Andromeda (TV series) based game. Hyperspace became Slipstream, etc. But didn't work for an Intellivision rom.

 

I tried.

ROM files have CRCs in them to make sure that the data hasn't gotten corrupted. Thus, if you change a byte, the emulator and CuttleCart will reject file because the CRC check failed.

 

If you had the BIN file instead, you should be able to modify it. Use the rom2bin and bin2rom tools that come with the SDK-1600 tools.

And thanks to that little bit of knowledge from Lathe26 we now have a change in the title screen:

 

 

YES!! Might play this more later, but "BS - GALACTICA" was basically the same space as "SPACE BATTLE"

 

Of course others are welcome to try to see if they can get the whole name in the title, but at least we are closer to what it should have been.

Neat! Disassembled, the title screen should be easily modifiable. It's just a bunch of bytes (decles).

That is what I'd like to learn. How do you disassemble a binary or rom image?

Start up a thread in the programming section if you're curious. Basically there's a disassembler available - you'd run it against the bin/rom, and out comes a bunch of assembler output. Now, most of it may be greek to you, but if you've already made it this far, you should be able to at least figure out where the "title" is. Simply replace those values and re-assemble into a new bin/rom.

 

I'll admit vast ignorance here as I haven't actually looked deeply at assembled Intellivision code, or at how the title is stored. I DO know how it's stored in the ASM source itself, and that part is pretty straightforward - I think. I know people have been disassembling commercial releases to see how they work - obviously this requires a fair bit of expertise and ASM understanding. But I think for a title swap, it should be pretty simple.

Thanks for sharing. Big fan of "BS" too. I love the new series as well.

i love them all as well. I wished syfy had picked up the blood and chrome series. That pilot show was freaking cool.

Nice thank you!
