PocketSPC player for the Nintendo DS. It is a SNES sound chip emulator on DS.
Currently, the only supported method of using this program is by using a flashcart with the PocketSPC.ds.gba file.
User guide
The .nds version has a space restriction, you will only be able to use roughly 2 megabytes of songs due to ram limitations.
The process you need to use to build an nds, is first add your spcs to pocketspc.arm9 using the builder (you can also use the c++ builder by MottZilla). Then you run creatends.bat and it will output a shiny new nds for you to use (wifi, gba mp, etc...).
There are a few example songs included if you don't want to go hunting for SPC's to play. If you do, a great source is http://www.snesmusic.org/.
Rom Builder
The rom builder requires the .NET framework version 1.1 or greater to be installed.
Run it in the same directory as the PocketSPC.ds.gba file and it will automatically find the current songs you have added. Then click Add Files to add in more spc's.
You can multi-select here as well. Select one or more files and click delete files to remove them from the .ds.gba file.
Add files from the command line using:
pocketspcbuilder -add blah.spc blah2.spc
You may use wildcards as well, such as:
pocketspcbuilder -add *.spc
Controls
Menu:
Up/Down - Move the current selection
A - Start the current selection playing
While the SPC is playing:
Select - Turn randomize next song on/off
B - Stop the SPC and go back to the menu system
Left - Previous song
Right - Next song
Up - Increase Preamp (volume)
Down - Decrease Preamp (volume)
