My first guide on how to make a sub routine had a lot of mistakes/errors. I will re-write it and tell you.

EDIT: You should start in this order. Like I did.

- Porting
- Text mods
- Map mods (I skipped this because I couldn't find a guide about it)
- Basic Coding (Sub-Routines, Jokers etc..)
- Advanced Coding

Alright, I have re-written my guide on how to make a sub-routine. Refer to it in the PS2DIS Tutorial section.
