I had a short problem upgrading the firmware to 2.0; it ‘bricked’ the device. After a bit of wiki reading and obtaining advice from djwillis on efnet#gp2xdev my SD card wasn’t playing well with the firmware upgrade software. I’m now the happy owner of a Linux-powered entertainment device! HUZZAH!
I’ve installed Quake 1, a Sega Master System emulator, a Mega Drive (Genesis) emulator, and can’t wait to see what else I can get running on this thing!
