First, I really like PortingKit... I got into Wine a year or two ago, got a few games up and running but PortingKit makes it a much more pleasant experience. So great job and thanks.
I've just tried Alien Shooter and I can get up to level 3 or 4 (not sure which one) and it then crashes out. This is output in the logs:
!!!ERROR 14:27:41!!!SOUND: 0x6A Invalid nsfx
!!!ERROR 14:28:24!!!TEXTURE: 0x8876086C Couldn't lock
!!!ERROR EXCEPTION 0x41AFDC!!!: Access violation write to 0x0
A quick Google and this reported (and fixed) bug on WineHQ https://bugs.winehq.org/show_bug.cgi?id=39874
looks very similar. It was fixed about 3 months ago, just wondering if the PortingKit is using this fixed version or if there is still a problem?
