A small Ultra Heart of Fire update:
We're in the endgame now, boys.
The new route shown here is a new Kanto route that will lead to a new city. Route 14 connects to new routes, which lead to the routes shown here. There will be plenty of new routes in the game along with around 3 new cities.
I've also included more screenshots of the Battle Roulette, accessible in the Game Corner and in the mini-Battle Frontier later on.
Again, if anybody wants to help out or be involved in some way, let me know.
A couple of things:
1) Have you gone to the Sevii Islands? Islands 1 - 6 are accessible before defeating the Elite Four, where Islands 4 - 6 contain more powerful trainers.
2) There might be an NPC that gives you a Lucky Egg. Maybe. I'm not exactly sure if I did away with him in the most recent version. If there is no such NPC anymore, Rainbow Isle has merchants that sell Lucky Eggs for BP.
3) Do you have the VS Seeker? You do not need to charge it for this game.
4) Did you change the difficulty settings?
Vanilla Firered's champion is 63, this hack's champion tops at 68 iirc, but you also have many more trainers available especially with Islands 4 - 6 being opened up and accessible before the Pokemon League.
