XDA has it for download, reading their forums you can get the standalone apk (doesnt work without the lib files) look for post with DSPManager_Open_desire attachement it installs just fine with rom manager- didn't try the update.zip but it should work as well,
crackling at full volume, but it seems to be overdriving (clipping) at that anyway, turn it down just a hair and it clears up, sounds as loud as full did prior, EQ and room effects are cool and footprint is small- App2sd works on it leaving 40KB total, 28k app 12k data and it has bluetooth EQ as well, makes voices sound alot clearer (removing some bass and boosting mid range)
The latest rom prject elite V2 has the older version included in it.
Older has individual sliders for frequency sets, new one has small graphic display.
