I never thought I'd see the day that this game ever got an update, but thanks to the work of one hacksrepairman, the game has been completed from notes I wrote as a child! Wow!

Honestly, it blows my mind that people still care about Shining Opal in the year of our lord NBA 2K23. This game, written by a child with no concept of how games should be made, restarted countless times, with wildly overreaching ambitions, has somehow kept enough of a following that someone decided they'd come in and finish the whole dang thing. While I've left the Pokémon ROM hacking space (more or less, I keep getting pulled back in no matter how hard I try to escape), I wanted to go in and fix up some stuff before posting it to my official channels, so I did some binary hacking for the first time in goddamn ever and boy was I reminded why I hated it. And that was even with help from the decomps! It's a wonder I ever made any hacks before 2017, frankly.
Now, while this is semi-official, meaning I've blessed this as the real 'final version' of Shining Opal, I had little control or oversight over how hacksrepairman interpreted my vague notes and scribblings, and have not vetted the hack for anything untoward, so buyer beware. I will not be doing any bugfixes from here on if I can help it, and all such bugs to be fixed should be reported on the official PokéCommunity thread so hacksrepairman can take a look if he so chooses. I wouldn't blame him for wanting to sleep for a million years after the absolute gigaeffort he put in. Bravo, my guy. Bravo.
