CI1 Source Code Petition


We’ve gathered here today to hear about proposal of open-sourcing CI1. There are many open-source games (not as many as the closed ones, but still there are many) nowadays. Not every one of them releases as that since the beginning - some of them just get open-sourced after few years when the sales are no longer too much profitable or for anniversaries or just because.

The latest big example of a game that got open-sourced after the release is old indie hit VVVVVV. It got open-source for 10th anniversary. It got some publicity and after something like ~1.5 year it got first update since 7 years which was created with help of community. Despite the bugfixes it got such things as: unlocked framerate, in-game timer and features for level creators. You can read more here: VVVVVV gets its first update in seven years, and it's a big one | PC Gamer

Have you heard of DOOM, Quake and Amnesia? They are open-source and DOOM especially is loved by people that port it to run it on every piece of tech in the existence.

If you’re worried that your game might end up getting cloned and stolen to make ton of cheap copies without contributing back then just choose some good copyleft license that prohibits that behavior. You don’t even have to open-source the graphics, but it would be nice and would make it easier for people wanting to tinker with it.

So I’m here to suggest open-sourcing the CI1.

List of arguments for open-sourcing the CI1:

  • The last update was released nearly 20 years ago (2002-12-30)
  • It has problems running on Windows newer than 7
  • It is only available for Windows OS, which means it could be ported for more systems
  • It could be improved by some hobbyists, either the technical stuff, adding new inputs support, new content, frame rate increase, resolution increase or all of them
  • It could be preserved
  • It is currently available to download for free so there’s nothing to lose in terms of profits

Here’s a good article that talks about open-sourcing games in more technical details:

Not only this but also the original version of CI2, because I’m pretty sure that isn’t really supported to begin with, oh yeah including the Christmas version.


Christmas edition is literally the same game but reskinned.
As of open sourcing original CI2, I’d rather make it that you need to have a copy of the game in order to access it/build it. Well, to CI1 too, though in that case it’s free anyway.

Of course you should need a copy of the game before accessing it, I mean I’m pretty sure that’s how open source content works anyway, at least with what I’m familiar with.

Yeah I know the Christmas edition is just the same game but reskinned but I only suggested that because of the exclusive assets it possesses, pretty sure only iA has them anyway.

While I would love this, CI2 is still being updated and most importantly it is paid, unlike CI1. So it’s harder to convince.

It isn’t supported but it was continued by the remastered version. And it is still available to buy on IA Studios site.

Yeah, that would work. There are some projects that let you use them if you provide your own copy of game files - heroes 3 fan recreation, diablo 1 in browsers

Yeah, CI1 could just go without that obstacle. It’s free anyway so there’s no problem.

It depends. Some work without providing your copy but it’s the case of legality (not exactly piracy mind you, some games are free)

But if CI1’s source code is released, UVEDX should also be released. Otherwise, it wouldn’t make much sense.

It would, actually, if uvedx functions have self-documenting names. This only prevents straight up compiling it.


Releasing a new UVE when.

Providing the source to you in a personal message is NOT the same as “releasing”. :angry:

This idea has merit, however anything I’ve made available in the past has been a constant source of further questions, support requests, and a general sink of time and energy on my part. Yes, even after explicitly stating that it’s unsupported.

The fact is that CI1 uses obsolete SDKs and is not directly compilable on any modern platform, and that is going to cause a lot of trouble for me. How many of the people who voted “Yes” in the poll above have the technical knowledge to actually do anything with the code? I could make it more usable before releasing, but that’s going to take even more time and energy on my part, and I currently can’t spare either.


I and Francis are ready to suffer because your code will be an epic learning material for us.
Here is a proof of Francis being ready to suffer.

UPD: Also this would help A TON for my idea of making a PSP CI1 port not gonna lie.


Does it matter? Most of them probably voted yes to have a chance of updated engine with maybe new content added. Also, actual publishing (I suggest github even if you don’t use git, but whatever goes) and the news about it may attract people that are experienced enough to dive into it.

I’d prefer you do not change anything there (including comments which probably are the most valuable stuff there for historical and development purpose. Some document with tips would be nice, but it’s up to you.


Can anybody tell me what is going on bec i can’t understand a thing from these replies

Basically people want InterAction studios to release the source code of the original Chicken Invaders game as it’s not supported and is an interesting material. My personal interest is how the project is organised because I have huge issues with this.

I have been debating this back and forth in my mind for several months. I have finally reached a decision. I will not be releasing the source code for Chicken Invaders 1, or any of my games, ever.

Just search for “Chicken Invaders” on Google Play. Look at all the copycat derivative games, the games “inspired” by Chicken Invaders, the games infringing on the Chicken Invaders copyright by using stolen graphics and sounds, the games even using the Chicken Invaders trademarked name. And that is after all the games I’ve taken down by filing for a trademark or copyright infringement claim.

Any source code I release would eventually be used to unlawfully create yet another unauthorized game, and I will be powerless to do anything about it.

I know some people would make good use of this source code, but the rest of humanity regrettably sucks. So, no.
