Someri Sound Engine is a sound/music playback routine mainly used by Hummer Team. It doesn't appear to be original, as it shares many similarities to the sound engine used in games developed and/or published by Athena, which is especially obvious with Deblock. The first known game to use it was Jing Ke Xin Zhuan.
There are four revisions of the engine, each time they improve it by changing some instruments and adding some new ones.
- Street Fighter IV
- AV Bishoujo Senshi Girl Fighting (?)
- Dragon Ball Z - Super Butoden 2
- Mortal Kombat II
- Yuu Yuu Hakusho Final
- Shisen Majiang 2
This revision is very similar to the first one.
- Kart Fighter
- Av Jiu Ji Ma Jiang 2
- Garou Densetsu Special
- Super Mario World
- Mortal Kombat II Special
- Power Rangers III
- Shin Samurai Spirits 2
- Earthworm Jim 3
- Mortal Kombat 4 (?)
That one could probably fit in Revision 2 but there are some instruments that haven't been used before.
- All games made by Ex-Hummer Team members use the second or third revisions.
