Alternative ending: Ramza vs Delita

I have been playing Final Fantasy Tactics: The War of the Lions on ePSXe. Since i play for free, i feel a little bit of guilty, so i want to make it hard. Thus i used FFT RUMBLE CHAOS CRASHDOWN RANDOMIZER mod. But the .Iso the mod created it is quite interesting. Well, first off, it max all stats of almost every characters, except the main character. Second, there are few battles that are out of place that has nothing to do with the plot. But the moment i realize something is up when i came to the final ending after defeating the final boss. Instead of the normal ending, Ramza teleported into the scene and tried to save the princess from Delita. My guess is that i somehow unlocked battles that was hidden away before the final release or the modder is messing with me. Either way, i want to share this with everyone. P/S: Yes, i have not beat the battle with Deilita, like the Wiegraf battle, the enermy had max stats while Ramza had normal stats, i had to use Cheat engine to win 1vs1 battle with Wiegarf and probably use it again to win with Deilita.
