"Extend" sound in SADX?
In SADX's sound test, you can find a sound named "Extend" under Jingle, it's a remastered version of 3D Blast's [alternative, not the S&K one] 1-up sound.
I'm trying to figure out if it's unused like the SA Internet Mode music (Jingle D). If it is, it must have been a scrapped 1-up sound - in the sound files of the PC version, it's named one_up.wma (well, if my server is online).
