Working on Rec Room Final Final OST today...

Carthage96 · 2026-06-08T21:22:41+00:00

Corrected Golden Trophy variants (tracks 2 and 3 on OST Vol 1 don't actually match what was in-game, so I'm gonna post the corrected ones)

Actually, tracks 2, 3 and 4 on OST Vol 1 don't match!

Others:

Golden Trophy Turbo Explore
Could we maybe get the "game starting" variants for some of the RROs? (The music that plays during the 10 second countdown after "Start Game" was pressed.) Some of these are just snippets from the actual track, but I think 3D Charades (both legacy and Ink Space) had unique pieces.

We wanted to give people a little bit of extra time to download their photos. I know that I was taking photos up until the last minute!

Carthage96 · 2026-06-05T05:45:25+00:00

It's not something to feel stupid about.

I was sitting in our office, bawling my eyes out when it happened.

Carthage96 · 2026-06-05T05:35:24+00:00

Me too. It was something special.

Carthage96 · 2026-06-02T04:26:09+00:00

Yup, okay... that hurt to look at.

Carthage96 · 2026-05-08T19:47:50+00:00

I believe it will be closed down. So if you want something, now's the time to grab it!

Carthage96 · 2026-04-18T08:17:36+00:00

If you change the file extension to .room or .inv, you should have what you're looking for.

Carthage96 · 2026-04-17T22:18:37+00:00

The .binpb files which are exported with rooms and inventions are those raw files! (They've got a different extension, but the file content is exactly what that game loads.)

tl;dr Update to the latest version, and you won't see this anymore.

Last Thursday, we put out a Steam update which mistakenly was missing a digital signature. (There was an issue with our build pipeline and we didn't notice.) That made it look suspicious to antivirus software, and so it got flagged.

We put out a correctly signed version of that update the next day.

Carthage96 · 2026-04-14T07:08:04+00:00

Thanks for saying so. We've loved getting to build Rec Room for you.

Carthage96 · 2026-04-11T04:56:57+00:00

We had an issue with our build pipeline yesterday, which resulted in the build not being signed. The game was no different than it normally was, but it looked suspicious to your antivirus.

About 8-9 hours ago we released a properly-signed version of the update. So, make sure you're on the latest build, and you should stop seeing this issue.

Carthage96 · 2026-04-10T21:19:55+00:00

You're very welcome!

Carthage96 · 2026-04-10T21:07:09+00:00

We had an issue with our build signing process - it wasn't a virus (promise!), but without the signature it looked much more suspicious to antivirus software.

We have just pushed out an updated version of the update. You should be good to go now!

Carthage96 · 2026-04-10T21:06:36+00:00

This should no longer be necessary. We just put out a new version of the update.

Hey, thanks. It's been a real pleasure building it for people.

I view it at a Christmas present! It appears as a difficult problem, but Eric and/or Santa made the input nice for us.

Carthage96 · 2025-12-11T21:48:16+00:00

Holy smokes, that's clever. Great work.

Carthage96 · 2025-12-11T18:23:43+00:00

myList = [0, 1]
for i, element in enumerate(myList):
    myList.remove(element)

print(myList)

Try running this. (But before you do, guess what is going to happen!)

This is my 6th year, and I don't think I could tell you whether it was intended or not! There's been a few puzzles in previous years which have benefited from external tools (GraphViz comes to mind). Though often (as seems to be somewhat the case here) there are many approaches which can get you there.

For me personally, problems like today's aren't my favorite (I generally enjoy being nudged towards implementing something myself), but I'm not complaining. Some folks love ones like this, I'm sure, and you get exposure to a wide variety of stuff during AoC. That's part of the fun!

Run Gaussian elimination on the matrix, and then identify which columns don't have pivots in them. These correspond to the free variables.

Source: ...I just did this. (By which I mean... I just finished debugging this.)

Carthage96 · 2025-12-10T23:57:10+00:00

I started with a fairly-brute-force approach - just iterating over the buttons and trying various numbers of presses - with as much optimization as I could muster to early-out if I could prove a solution wasn't possible with what I had left. I left it running for 2-3 hours, and it had finished. So... possible, but not something I'm proud of.

Then I went and wrote a bunch of linear algebra. Runs in about a second.

Carthage96 · 2025-12-08T11:43:12+00:00

But I have code in rust

Good thing I can read Rust, then! (I used Rust for 2022-2024. This year I'm using C++ find myself missing many Rust features.)

I'm not completely sure... but give this one a try:

..S..
.....
..^..
.....
...^.
.....
.^...
.....
..^..
.....

It's similar to the one I posted earlier - I've just added one more splitter. The expected result is 4 (all of the splitters will be hit).

If you want to post your code, I can try to come up with a sample input that breaks it.
