WonderSwan (Wich ?)

HI im wondering wich WonderSwan emulator would be the best for my 2.6 "Ported" Eloader.
Here are the choices :

Cygne
eSwan
Oswan PSP
Pswan

i'm wondering too
but to get black waves use a plain black background (saved on your flash not the sony's custom wallpaper) using that prog to flash custom bg's to your flash

im in 2.6 is it good anyway if I do it ?
And the only one that do it is Flash-Me but it doesnt seems to work !

it is good, it makes it look more sleek.
