Well, now that you said that you have a laptop, it's fairly clear that you have an integrated graphics chip. Since laptops don't have enough room, they have to use integrated parts (read: permanently attached to the motherboard) so that everything will fit. This isn't a problem for desktop computers so they can use non-integrated solutions such as actual video cards. Because a full graphics hardware need to be fit in a tiny chip, integrated graphics chips are never as good as actual video cards. So they lack many of the features that video cards have. (in this case T&L) As for T&L, it's a graphics technique known as Transform & Lighting which is responsible for a number of special effects in games. Now, Dreamcast emulators need this very function from the graphics hardware in order to render Dreamcast graphics correctly. Since many integrated graphics chips (most notoriously Intel's chips) lack proper T&L support, you'll see messed up graphics. Like I said earlier, you can forget about trying to get the emulator to run properly on your laptop. Same goes for every other Dreamcast emulator. Get your self a decent desktop computer with a decent non-integrated graphics card. That's the only way you are going to get acceptable graphics from Dreamcast emulators. P.S. You can check what integrated chip you have by clicking Start --> Run, typing dxdiag and press Enter. The DirectX Diagnostics program should run. Then click on the Display tab and see what it says Under "Device:".
