Just as the thread title states, I’ve had a few problems with those games from their respective 2 in 1 sets.
While the problems with tokimeki check-in is only minor (the first video is a black screen and the second only goes around ten seconds in before freezing (the whole game doesn’t freeze, just the video) whilst the audio still plays in the background), target pheromone stops responding after the initial video which meant that I had to force close it through task manager (I couldn’t even get back to the desktop), fix the broken screen resolution and log out and back in to restore the task bar.
The computer in question is running windows XP SP3 which is fully up to date (including directX which I had to sort out after moero downhill night blaze wouldn’t work).
