Just signed up to say I love this patch. I've just started playing it on my DSTwo and it runs flawlessly.
Few things to note though, after talking to the first photographer and asking for a picture the game will freeze with the music unaffected.
Also when heading out and going into the wild grass without any Pokemon (start of the game), you will have a MissingNO-looking sprite @ Level 1 with 1 HP. If it faints you will be transported to the Viridian City Pokemon Center effectively forcing you to start over. Going into the Pokemon menu will also crash the game.
Can't wait to see what else you have in store!
