Endless Paradigm

Hello.. well after reading some tutorials for customizing the XMB and all the stuff inside the psp, I decide to beginin to make my own rco.. but I have some issues with some RCO and one of them is the "opening pluggin"

To edit my own image I  prepared everything in photoshop, add new alpha channel, use indexed color (256 colors or less), then go back to RGB, save in bitmap of 32bits with alpha channel active.. Then when I edit the Opening pluggin.rco with RCO editor the black window show the new edited letter but when I load the theme with this new rco I just see a white box on the screen....This buggin me cause I have done others images and works fine but for some reason some times the images doesn´t show properly.. I thinks this is little tricky..

Please someone know the reason for this happens I mean the white screen instead of images!

What are the dimensions?  The PSP has some pretty tight memory limits on these things.

(note, memory used = width × height × colour depth)

make icon as png rather than .bmp and then use pngforptf converter and try not to make it too large.

Ok I will try to make them smaller..

So that's the same issue with the XMB icons,they dissapears for memory lacks.. I will try to save them in png...

The color depth that I used is 32bits.
