There's already a bug filed for a crash upon selecting new game: 5526.

At first I was getting crashes each time I tried to load a save, but after changing my resolution I am now unable to reproduce that. I also haven't crashed upon continue.

(I'm adding this comment to several bugs here...sorry if you see it multiple times.)

There were some memory corruption bugs in the initial Humble Bundle build, which we believe have been tracked down and fixed now. Most of the crashes are probably due to these.

Those getting Floating Point Exception crashes during cutscenes: that was my fault, I screwed up something hooking up the Bink audio output code. This is also fixed, I think.

Here is a test build, please try it and report back. It's a 2.1 megabyte download: just untar it and overwrite the two files in your game installation.

This build also has joystick support and working FSAA (if the game is way slower for you, you can turn off FSAA in the options menu).

There are still some bugs, but this should be MUCH more playable.

Download it here:

   http://treefort.icculus.org/psychonauts/psychonuts-linux-test-06032012.tar.bz2

We'll do a more formal build once we get some feedback.

(I'm adding this comment to many bugs that this fix might apply to...sorry if you see it multiple times or it doesn't _actually_ fix your issue.)

Here is a new test build, please try it and report back. It's a 2.1 megabyte
download, so you don't have to redownload the whole game again.

This is meant to fix crash bugs mostly. We still have rendering issues, etc to sort out. If this didn't fix your issue, please report it on this bug. If there are still other unrelated issues, please file a new bug or add yourself to the CC list of one of the other bugs. Here's the open bug list if you want to check for others with the same problem:

Steam users: you'll get this through Steam shortly.

Linux users, download this...

  http://treefort.icculus.org/psychonauts/psychonauts-linux-0.3-patch.tar.bz2

...and unpack it. Overwrite Psychonauts and libSDL-1.2.so.0 with it. This works with either of the first two builds from HumbleBundle.com.

Mac users that aren't using Steam, download this...

  http://treefort.icculus.org/psychonauts/psychonauts-mac-0.3-patch.tar.bz2

...double click it, and run the patcher program it produces.

We'll do a more formal build once we get some feedback.

--ryan.

This should be fixed now.
