Keep checking the 'Where's Waldo' release thread or the unofficial DSTT firmware thread. Any solution is likely to appear in those places first.
The thing is , if they released a firmware every time a game doesn't work, updates could be every week! If you look at the list of games per release you will notice a bunch of games are fixed with each update. If more new recent games don't work, and I'm talking about more important games such as Pokemon as you mentioned, then I'm sure they will update and release a new one ASAP. Mentioning just one single game, isn't going to help or encourage them to fix it any faster or make a release specifically for it.
