ThatotherDev a Coder who has released homebrew for the PS3, Nintendo Wii, Nintendo DS and Windows has posted this news:

Neo tanks has been updated to match the more recent PS3 version (so it looks a bit different and you can take control of tanks).
Swingball 2 has newly added music (The Jackals by ara), the menus are now navigated by pointing and clicking on buttons and the level that was remade in the last PS3 release has been updated here to match.
Neo Tanks v0.2
Swingball 2 v0.4
