Doom2 Asteroids [code exec]

[kgsws]

As a kind of art project i have created asteroids game for Doom.

It uses my save game exploit to run in original Doom2 version 1.9, or shareware.

This time it is a JPEG image that can be loaded as a doom save game.

 

 

Here is a direct link to the image. You still have to rename it properly.

 

I hope someone finds this interesting.

Great stuff! Looks like we are going full circle...

[Noiser]

This is so cool! Congrats!

[Gez]

It's a jpg, no it's a save, no it's Asteroid!

 

This is both absurd and awesome, well done!

You impressed Gez. That is a considerable feat (no joke.)

 

And along that, im impressed too. A brilliant use of the Ace Engine, and experimental art. Will be on Wiki.

 

Thank you for breaking the boundaries.

"Can it run Doom?" has changed to "Can Doom run it?"

 

Very impressive!

It's a chimera. Two independent file formats together. I had to use JPEG instead of PNG since PNG headers make it incompatible with Doom save game.

(i also had to create save game compatible with doom1.wad and doom2.wad at the same time; one loads E1M9 the other loads MAP30)

Indeed, this is the reason why i chose asteroids.

That is actually a really good idea!

I agree; this was, as mentioned earlier, a planned feature for DooM.  This is similar to Wolf 3d's secret level being a Pac Man maze, and the Commander Keen playing Pong.  As I recall, only a few subroutines were made, and it didn't really go anywhere, so it was removed.  Nice touch putting it back in!  :)

Even though this is a bit of useless information, I find it funny that cjxl, in converting the JPEG to a newer format, can recover an exact JPEG including your save game via the corresponding djxl tool. :P

No way.... No fucking way.... This is kick-ass man. Well done.

Interesting, I didn't even know this was a thing....

[Teo Slayer]

That's so cool, good job

[Biodegradable]

I don't know how I missed this thread, but holy shit, that's really neat.

[Wadmodder Shalton]

This project should be mentioned in the Automap Asteroids page on the DoomWiki.

[fraggle]

Amazing. Well done.

[RetroAkaMe]

Woah! Have to try that!

[Wadmodder Shalton]

I wish to see LGR cover this on his Blerbs channel.

 

Also, should that Asteroids level in later versions of the Zandronum PWAD Doom Center be also mentioned on the DoomWiki's Automap Asteroids page.

[JBerg]

Absolutely amazing!

totally missed this thread... this is truly legendary. I really hope Romero tries this doom 2 astroids, since it was apparently already a planned feature that got scrapped
