Final Fantasy Hacktics

Hello everyone, I have a small problem and I needed to enlist the help of more experienced people this time, because today was a very exhausting day for me and I'm very tired, my head is about to "explode" with so much confusion, so yeah difficult to solve this alone...
I'm still getting the hang of using the game creation/modification tools. And since I'm still not able to create a dedicated mod, I'm changing mine in a way that it follows the same path as the original vanilla. However, as I changed all the characters to create a "new story", I am needing to change the lines of the dialogues during the game.
I'm currently changing the dialogs for the starting events (involving Algus), and when I finished and saved the dialogs for the events (025 Introducing Algus) and (027 Returning to Igros), I noticed that something made the name of one of the jobs, stay in Chinese, I tried to return to normal with FFTactext, but it continued with another error...
Are there any limitations I should avoid when changing original campaign dialogues? Because I'm not putting too much text or using special characters, just a few words... I would like your help, if possible.
Since I'm at the beginning of the game, the only mistake I could notice was in the name of the job, so I'll probably have problems with other words as the game progresses. Solving this before dedicating myself more would be very good.

My world map is completely dark, I only see the objective points to walk between them. Earlier today everything was ok. I copied a friend's video configuration and the map still doesn't appear for me, and his map appears normally. I've been playing on version 2.0.2 for years but this time I can't solve it.
I downloaded versions 1.7, 2.05 and even 1.8 and in all of them the world map is not normal. I already deleted the ePSXe records from windows and reconfigured the emulators, and it had no effect... I don't know what else to do to get it back to normal, please help me.

Hi, I'm new here on the forum and it's the first time I try to mess with something like this! (Sorry for my English, I won't have the opportunity to study this language until next year!). I have two initial questions and I would like your support to help me find the right help, thank you in advance!

1) Sprites in Battle: I noticed that if we enter a battle with 5 non-original sprites, their image is distorted (A bug). Is it possible for me to make this limitation go away and I can use a little more altered sprites in the same battle, or is this an unsolved limitation due to the game being old? I don't want to literally change every character in battle, but I would like to have more options in combat.

2)I don't understand anything about programs or utility features to modify this game (not my area), so I would like, if possible, to guide me to links where there are tutorials for beginners. It doesn't have to be anything too advanced as I won't be releasing the game or even making any major changes at the moment. I would just like to change a few things for personal use. I want to step away from our beloved classic version and make the game a little different, but nothing in the Journey of Five style (Which I played from the beginning and thought it was amazing! Congratulations to the creators.) I would like some more basic tutorials, things like: change something in a battle, a tutorial on how to use FFTorgASM and even ATTACK.OUT... I took a quick look through the forum and found some useful tips and saved them to study later, but I didn't find anything about these programs, I believe there is something teaching, so if you can leave a link so I can see how to use all of this, I would be grateful !

OBS: I just remembered! If you can tell me where I can find a tutorial to change lines during battles too, it will be of great help. I would like to change some lines in the story if possible.

I'm happy to meet you, I hope I can learn a lot here, and who knows, maybe in the future I can teach you something too!
