+# ToneMatrix 0.92
+
+Hello, I am Tanner Babcock. This is a restoration, out of several in a series, of one of my PSP homebrew programs. *ToneMatrix* version 0.92 was completed May 2012. The code was all written by me.
+
+## Original Readme
+
+ToneMatrix is a 16-step drum machine. The Y (vertical) axis represents eight different sounds, and more than one can be played at a time. The X (horizontal) axis represents one 4/4 measure in sixteenth-notes.
+
+Select a node on the grid with the **D-pad** and the **X** button, and that sound will be played in time. Press **O** to stop/resume playing. Press **[] (square)** to mute the row the cursor is on. Press **/\ (triangle)** to mute every row except the row the cursor is on. You can mute more than one row at once.
+
+Press **START** to use the menu, and use the **D-pad** to select a menu item or change a value (like the tempo), and **X (cross)** to confirm your choice. Press **SELECT** for help.
+
+You can play up to twelve measures in a row by using the **R and L** triggers, or by switching the "grid" value in the **START** mneu. If "loop all" is on, then the measures will play one after another. If it is off, it will only repeat one measure. It is recommended that you stop playback before editing another grid.
+
+## Installation
+
+If you have custom firmware or a homebrew-enabled PSP, place the **"unsigned"** folder into the `/PSP/GAME` folder on your Memory Stick. If you have official firmware on your PSP (or if you have a PSPgo), place the **"signed"** folder into the `/PSP/GAME` folder on your Memory Stick.
