android is the best for portability. this is what i have now. it should be able to do every thing n64 and below. the ds emulator also works great with a good stylus. https://www.amazon.ca/S7800-Handheld-1280x800px-Simulators-Joysticks/dp/B00H5FS870/ref=sr_1_2?ie=UTF8&qid=1483936371&sr=8-2&keywords=jxd+s7800b
you can also try something from the JXD lineup. I have heard that they are great for emulation. The older models are still pretty good if you are looking to emulate up to 4th gen (psx, N64, etc.) and they kind of look like Vitas .
