Hi,
I tried the unpublished crosstie for this, after installing .Net 2.0, and it worked perfectly. Then I installed XNA Framework 4.0, and that also worked. Then I played Serious Sam Double D with very few issues.
Of course, maybe SSDD doesn't require much of .NEt 4.0, and other apps can still crash spectacularly. In fact, Breath of Death VII does so under the same circumstances as SSDD.
But it's looking good!
