P2Ninja - a P2 Disassembler (beta)

Surac · 2021-04-23 07:34

Hello.

here you can find a P2 disassembler for Windows. It is written in C# and uses the .Net Framework.
This is the very first release with only GUI and only Windows as target OS

Intention

I have written this disassembler to spoon-feed me the P2 assembler syntax and flags/condition system. I share this program for nothing more than science. If you can make any use out of it. perfect!

Installation:

just download the attached .zip file and expand it where you like.

Usage:

Start the P2Ninja.exe with a double-click. A P2Ninja window will open.
Now click the "Open" button and choose a P2 bin, or binary file.
The disassembled file appears in the big textbox of the P2Ninja window.
This is a Read-only textbox. If you like to save the contend just copy-paste everything
from the textbox to a text editor.

Features

knows how to work with AUGS and AUGD instructions and "constructs" the next instruction to contain proper syntax for PNUT.
hopefully knows all P2 instructions
hopefully knows all P2 alias instructions (like NEG $1,$1 becomes only NEG $1)
replaces addresses of the special registers (PA, PB, PRTA....) with their names.

Limitations

Happily, disassembles data fields. There is no way to distinct data and instructions.
PNUT contains many ways to input illegal parameters for assembler instructions and silently produces some instruction. The Disassembler only sees the bin file and the P2 documentation.
It will produce what is written down in the bin file. So, any labels, symbols and comments are lost.
Cannot see org, orgf, orgh instruction. the .bin file is assumed to begin with address 0 in COG ram and go on to LUT and then HUB.
