Attention: Noob here (Emulator crash)

I'm currently on my laptop, here is the info:

Windows 7 64bits
4GB RAM
ATI Mobility Radeon HD 5470
Intel core i5 - 2.6Ghz

(Yeah, my laptop specs are low but its 4years old xD)

As stated by ssshadow, maybe you're using your Intel iGPU for rendering, and it lacks some OpenGL extensions, and that causes errors like the one you have. You said you have an i5 2.6Ghz, but you need to provide a little more. Run CPU-Z so we know what CPU you actually have. You can download it from here:

If you happen to have an Intel iGPU, you may disable it in the BIOS of your laptop. But if you can't disable it, the renaming trick could work. Your HD 5470 is capable to run the emulator fine.
