Yes, the blurriness is the billinear (or trillinear) filtering being turned on, even if point is selected. You can get it to turn off by doing the following:
1. go to the menu and changing the setting to billinear and returning to your game
2. return to the menu again and change it back to point.
This will make it use point.
Hope this helps.
I noticed something a little odd last night. I was trying out different games and two had a weird issue. For both Buck Rodgers and Demolition Man, when they started up, their opening animation started in a loop and got 'stuck'.
For instance, in Demolition Man, there is a graphic vertically scrolling in the background and then the title appears over top of it. What happened was the background graphic kept scrolling (and music playing), but the logo never appeared. None of the controls (start, a, b, c) seem to do anything to start the game either. I just reloaded the game and everything seemed fine after that.
Same sort of thing happened with Buck Rodgers.
I don't think it was an issue with the roms, but maybe how they were launched? Anyway, I thought you should know. Let me know if you need anymore info.
Thanks again
