PiKiss Dolphin not working and other things.

I tried to get Dolphin on PiKiss and it said it downloaded successfully and i can see that it had downloaded the necessary files except the dolphin-emu part which is weird because the rest downloaded. I don't have a 5V power supply but i don't think this is the issue. Other games also don't work like half life and fallout 2. Fallout said it didn't have the right text font. Please help

PiKiss may be outdated now

Is there any alternative that’s easy?
