When i talk about U-boot im talking about SH3 GWX 3.0 the best simulator about W.W. II. I don't care about sh4 or 5. And when i play sh3 i use to settings to 80-90% real why i don't play at 100%? Because its only a game...and i like to have fun when i play. To much difficulty spoil my Zen status when im in patrol!
