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.
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.
When I wrote PSP software as a teenager, I used a Windows build of the universally-known PSP SDK, through Wine, on my Mac. The build process revolves around GNU Make, but there are many extra steps. Every PSP binary is named EBOOT.PBP ("PSP binary package"). The actual machine code is only one out of up to eight elements.
PARAM.SFO- Metadata about the program, contains its title, version, language, and parental rating - the program will not be recognized at all if this is not presentDATA.PSP- The binary itself, usually comes as a *.elf or a *.prx (in typical Executable and Linkable format), technically has no filename until it's dumped from the package
A package really only needs these first two, the six remaining elements are totally optional.
DATA.PSAR- Compressed archive for system software updates or video game updatesICON0.PNG- The icon of the game or app, appears in the vertical list next to the others when in the XMBICON1.PMF- A short animation that takes the place ofICON0.PNGwhen focused - no audio included (.PMF is a native video format on PSP, .PAM is the PS3 version)PIC0.PNG- A caption or description image, appears on top ofPIC1.PNGand after a short delayPIC1.PNG- The background image that appears behind the XMB icons when focusedSND0.AC3- Sound that plays - often theme music for a game or a movie
One specifies which real files they want compiled into their EBOOT via the Makefile. The PARAM.SFO is generated by mksfo, the PRX is built from psp-prxgen, and the PBP is packaged with pack-pbp (it can be unpackaged with unpack-pbp).
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.
