I'm a minecraft modder and I'm fairly decent at it. But what seems to bug me is when I try to make a mod for personal use it never works.

I develop a mod that adds a new recipe, a new recipe only and it works but when I develop a mod that adds new items to the game it never works.

I make mods with mod loader.

I recompile the code, it works.

I test it in mcp, it works.

I reobfuscate (generate the classes), and it works.

But when I put the mods in the minecraft .jar and run the game it black screens. Yes i made the mods with modloader and yes i had modloader in the jar and yes i deleted the meta-inf file.

So please any modder out there who has some degree of experience, please help me.
