What`s the best power source option?

[Tsukimaru]

hey there I would like to know what kind of power source (battery) should I use to make a SNESp

I had in mind to use 3 9v square batteries, but any ideas are welcome

*Note: My goal is to make it least 10 hours on before the batteries run dry

Unless you want it to be HUGE there's no way your gonna make it last that long.

If you use 9v alkaline, that's pretty much true. But if you use Li-ions or li-polys, and a Snes clone, 10 hours is perfectly attainable in a reasonable form factor.

And just to reiterate, 9v alkaline batteries are a major no-no. You would get very little playtime, and you would go broke replacing them.
