BUGS:
snow warning sometime says the player's pokemon's ability instead of well, snow warning i.e. (I have a steelix and i battled an amaura, instead of saying "amura's snow warning made it hail" is says "amura's sturdy made it hail",
trainers uses item that are not for battle, i.e. my rival uses red shard to heal his pokemon, some instances they uses held items such as eviolite and life orb, though it doesn't heal their pokemon, it sometimes even lessens the pokemon's HP,
normal charizard can't learn solarbeam via tm,
at the beginning when you talk to the 2 rear guards blocking the door to Johto the game freezes,
ckb katana/cbk katana(the one from the daimyo in Red Town) vanishes in your bag, even after having the message say that you've received it, (nvm found it on the key items pocket)
some of the signs at the bus and ferry station freezes the game if you try to read it when you haven't got the right card/ticket/pass for the door the sign corresponds to,
in johto right at the beginning, the trainer who is supposed to be Youngster Joey battles you every time you take step in his line of sight even after you've just battled him, (p.s. not sure if this is intentional, but I ended up harassing the poor guy for exp and money, I've even drag him up to the front of Dark Cave)
at the kolloseum(doubles), after the third battle (Lt. Surge) it changes into the PWT battles, also after I've defeated PWT battles it teleported me into the PWT's location, and you can no longer progress in kolloseum if you try to rebattle again, you'll be stuck in a loop (battle Brock, then Misty, after that Lt. Surge shows up and won't battle you, and you can't go out either the only option is to talk to the announcer/host then he'll say the tournament begins and you'll battle Brock again, then Misty then Lt. Surge shows up and you know how the story goes)
rocky helmet,life orb,black sludge doesn't work.(perhaps they were not scripted yet, I only got these by using a cheat code cause I was upset that I can't get them via the kolloseum cause as I've mentioned it turned into PWT battles, but they don't work anyways :D I'm not sure if eviolite and assault vest don't work either)
after finishing inverse battle at the restaurant near the pokemon center at Olivine, all battles after that becomes inverse battle including wild encounters.
at Mt. Mortar there are lots of character with Red's sprite that does nothing (not scripted I guess) they're all over Mt. Mortar just standing there doing nothing.
lunar dance doesn't work, it only makes the user faint but not heal the pokemon that switches in.
brine only does the normal damage even if the enemy's hp is halved.
TM08(Focus Blast) and TM10(Energy Ball) description in the bag is wrong, also TM10 vanishes after use, and after using TM10 all the other TMs started to vanish after 1 use though they returned to their BW mechanic after the use of an HM,
at the villa in the south-west of Cherrygrove City, when you enter the ladder going down to the EV training place, it will teleport you in the pokemon league instead(exactly at the part where you fight Blue), after you've defeated Blue then Oak shows up and you'll enter the Hall of Fame and watch the end credits.
at the same villa, the ship that is supposed to be used to travel between region is nowhere to be found, and the player's zoo/farm is nonexistent.
at Ecruteak City Palkia shows up at the tower without triggering it's event( I ended up capturing it),
at Lake of Rage I've defeated all the rockets at the Lab, without triggering the event(talking to Blaine and Fuji) and now I can't catch Mewtwo 2.0 (he's not on the island where he's supposed to be, even after returning to Blaine and Fuji and talking to them once more)
P.S. I actually enjoyed this hack (my play time is over 200 hrs) so please address these bugs.
