ps2gsm is a GSMWavePlayerPlugin that runs on PogoShell. It can play Wave files compressed by Sound Recorder on Windows.

It uses the same GSM audio compression algorithm as mobile phones (au, not DoCoMo), and it is about 1/10 compared to ordinary uncompressed PCM. A 8MByteROM at 22kHz can contain roughly 30 minutes of audio, and about 1 hour at 11kHz.

Note: Only works with PogoShell2.0b3/b4.

Installation

Copy gsm.bin under PogoShell2\root\.shell\plugins\.

Open PogoShell2\root\.shell\pogo.cfg with notepad, then append this line: wav 3 gsm.bin 0
