Q: Eh? BPS file? How do I use that?!
A: Obtain a BPS patcher for your platform of choice (Floating IPS is recommended), and use it to apply the patch downloaded on this page to a fresh copy of Pokémon Emerald.

Q: When I try to start a new game, I get a message about my clock battery running dry!
or Q: After I set the clock, the clock stays stuck at that time forever!
A: Enable the Real Time Clock in your emulator.
Q: Why can't I add anybody to the Phone Card?
A: The Phone Card isn't finished yet, so you can't yet register regular trainers.

A: Yup!
Q: How far can I go?/Is Kanto in this version?/RELEASE NEW BETA NAO
A: This version of the game was remade from the ground up and only reaches Sudowoodo (much like v1 did, way back when). If you want to play the older, more "complete", but generally worse v2 from 2013, you can download it here.
Q: I found a bug/glitch/oddity!
A: Whoops, my bad (usually)! I'd appreciate it if you left me a comment down below, posted about it in the Discord server, or reported it on the thread at PokéCommunity.
