Having trouble modding Minecraft old_alpha rd-132328

So, I'm trying to mod one of the oldest versions of Minecraft. I've been doing pretty well so far, had no errors in the console, play test ran fine, texture/models looked fine and worked correctly. But when I try to put it into my Minecraft launcher, when I run it it won't work. I've renamed the .jar and .json files, referenced other versions to make sure the file layout for mine was correct, and did a run-through of the .json - twice, making sure I changed the ID.

The log from the Game Output tab (If Launcher Log is needed, comment below.):

/terrain.png -> 1
java.lang.RuntimeException: !!

That's pretty much all. I'll put the main code as well:

Thanks in advance guys! if you need any more information, just ask. I'll be following this post pretty frequently.

P.S: This is my first post, so forgive me if I made any errors or didn't make something clear! I'm very new to this, and only 13, so any positive criticism, ideas, tips, would all be greatly appreciated! Also, yes, I looked all over google to find the answer to my question, but didn't find anything even remotely close to what I was looking for, in fact, I don't think many people have trying to do what I am currently doing right now, especially not in only the second version of this game currently available. I chose ad-132328 because of its simplicity and basic layout of code, that way, because I'm fairly new to this, I could get a good idea of what I'm modifying, and have a basic template! :)

P.P.S: You will need some sort of class-reading software to inspect the .class files. I recommend JD-Gui, it free, incredibly easy to use, and great for editing as well!
