i know, i'm really not up to this task, but i've found an interesting web page which seems to have done some work in identifying which components are used in the S10:
ICs: SAMSUNG KGA0E000BA, E201, 622ARM, FU0337AA
ICs: Silicon Laboratories Si471x, SI4700B15, 0617BG, KABG
and some additional pictures about the display and the battery:
unfortunately, i don't have the skills or time to do any further work, but if I can help by searching something about the ICs or something else, i would kindly do these things!
Edit: The Player firmware is about 1,8 megabytes size - all written in the ROM as far as i know.
To which person should I give all these information?
