Implementation of ROHM ADPCM Playback (MFi Version `0200` / `0301`)

Applications developed for F/P/D 900i–902i models include MLD files intended for the ROHM sound chip, and their ADPCM format differs from that used for FueTrek.
On the internet, FueTrek ADPCM is said to be “G.721 Linear ADPCM,” while ROHM ADPCM is said to be “VOX ADPCM,” but I cannot verify the accuracy of this information.
