Q: Eh? IPS file? How do I use that?!
A: Obtain an IPS patcher for your platform of choice (Lunar IPS is recommended for Windows), and use it to apply the patch downloaded on this page to a fresh copy of Pokémon Emerald.
Q: When I start up my game, I get a message about my 1M sub-circuit board not being installed!
A: Change your emulator's save type to Flash 128K.
Q: How far can I go?/The gatehouse on Route 5 won't let me past!
A: Really sorry about that, but beating the Klindor City gym leaders is as far as the latest beta goes. If you want to get the latest news on the development of Shining Opal, subscribe to the RSS feed on my blog!
Q: I found a bug/glitch/oddity!
A: Whoops, my bad (usually)! I'd appreciate it if you left me a comment down below, sent me an email from the About page, or reported it on the thread at PokéCommunity or Pokémon Hackers Online.
