Final Fantasy Hacktics

Run into a new problem. I'll relay some things I've done first:
I've gone through the site's tutorial on ASM hacking, and have successfully reconstructed the fire element cure.
to help draw parallels to the psp version of the game, i thought i would boot up fftpatcher and the debugger for wotl and make the same mod to this version. only problem now is the debugger doesn't seem to have any effect on the game itself. The memory loaded on the debugger is completely blank, every byte filled with question marks and the guide to the right all blank dots.
i then tried to draw a breakpoint on cure's Y value (obtained from fftpatcher), for its default calculation, and then make the game access this value results in the game... not breaking. no breakpoint occurs and the debugger fails to read the value at this memory location. I thought maybe this would help shed light on the memory issue and it seems it has.
Is this an issue i can resolve, or is this universal and there is no solution?

Oh of course! i can't believe i didn't think to check the emulator itself for a disassembly! that will certainly make future endeavours quite a bit easier, thank you.
as for starting with the PSX version, I believe that adaptation instead if learning from scratch may be far easier, so I will take your advice and start with that. thank you very much for the input!

I certainly appreciate the feedback as to the difficulty but i'm still not sure where I can read the assembly code. editing the disc ISO with notepad++ doesn't work, as many of the characters are nul.
as for googling what ASM is, it's a language used by computers to assemble a program. it can only take a certain function, and a hexadecimal value for the function, ranging from A to F for each digit. I did some research before asking the main question, I really just don't know where i can access it

I'm trying to make a mod for my game that allows chocobos, and perhaps other monster units, to wear armour at least and have a separate job wheel from human units at best. However, Since this doesn't seem to be possible using fftpatcher or lioneditor, i read about and found that an ASM hack is needed to recode the game at its fundamentals. I also have no idea where I can acquire something like this, since google isn't helping. a link to a download for a program that can read assembly code would be greatly appreciated, thank you.
