Meteor - an Asteroids Clone
« on: March 06, 2016, 15:13:07 PM »
Did you know that Mattel had originally made an Asteroids clone for the Intellivision called Meteor?  

Quote
Astrosmash started out as a clone of the arcade game Asteroids, called Meteor!. The game wasn't very big, so John Sohl used the extra room in the cartridge to come up with a variation called Avalanche using the same graphics and sound effects. At the last minute, afraid of a lawsuit from Atari, the Mattel lawyers killed the Asteroids-like Meteor!. Rather than risk introducing bugs by deleting code, John simply put a branch around the opening-screen menu straight into the Avalanche! variation, which was released under the name Astrosmash. Very rarely, when there's a glitch hitting RESET, the Asteroids version will show up on screen.

Here is a video of Meteor in action...

It is possible to get the game to work more easily using the jzIntv emulator using the following steps:

Copy astro.bin to, say, "mod_astro.bin". Then, make a text file named "mod_astro.cfg" that contains simply:

[macro]
@p506A 0

You can then run "jzintv mod_astro.bin" and you should have the game menu enabled after the title screen. Press [1] then [Enter] for Astrosmash, or [2] then [Enter] for Meteor.

You can make the modification permanent by running "rom_merge" on the binary:

rom_merge mod_astro.bin astro_meteor.bin

That will write a new BIN+CFG for Astrosmash with Meteor permanently enabled. That should play in any emulator, not just jzIntv.

It's really cool to see this!  It's too back it was never officially released as its own game.

Neat, thanks for posting this!  Years ago I used the ECS to access the sprites from the cartridge, but I never could get the 'reset' glitch to work. 

Now I know what I was missing :)
