well well...

after a week of bugtesting and endless reflashing and a couple of brick recoverys (lol)
here wee go:

   

V0.3 of my little clock mod for 3.55-kmeaw
* finally compatible with both slim and fat models
* no more corrupted graphics in ingame XMB

it's a step forward but there's still things to do.
my research led me to see that fat and slim flash files somehow behave very differently.
i used modules from a fat one on a slim and it resulted in imminent freezing and some random gui slowdonws. Not a good sign.

i used modules from 3.55-kmeaw installed on a slim and managed to produce a stable set of modules that works on both fat and slim now. I also got rid of the clock face corrupting on imgame xmb which bugged me for a long, long time.

im not going to post any actual research results until i really know how things work, but
it seems that the first steps towards proper flash0 themes have been taken :)
