recommend some shootemups (us or jap) for the GBA

Hi I am looking for some mindless shootemup action for my GBA SP2. I
dont mind ( and would appreciate) if you recommend some JAP releases
too as those games require little text and tend to be playable even by
non jap readers like myself.

The ones I already have:


Rtype 3
Iridion 3d and 3d2
Gradius Advance
Star x (kinda Star foxish shooter but a shooter never the less)



thanks for any helP!!!
