What are the minimum specs to run AndroiDolphin?

Just wondering because my 3 or 4 year old Droid X is not allowed to download the app.

Well, for one, you probably need more than 512MB of RAM, according to the Android usage guide: https://forums.dolphin-emu.org/Thread-android-usage-guide

Additionally, you probably should be using a more recent version of Android (the Droid X shipped with Android 2.3 Gingerbread). At any rate, Dolphin on Android isn't in any shape to run games at playable speed (and if it were, your phone's probably a bit too old).

EDIT: The Google Play page specifically says you need Android 4.0+, https://play.google.com/store/apps/details?id=org.dolphinemu.dolphinemu&hl=en
