>>Is there any public domain FLL/DLL with functions for reading byte/string from memory address(s) ? Something like PEEK(segment,offset). I didn't find any solutions in WIN32 API.

>Sort of, but not really. There are at least two API calls, lstrcopy() and RtlMoveMemory() that can be used to copy a block of memory specified as a 32 bit virtual address. lstrcopy() copies a null terminated string to a specified buffer location up to the first null character, while RtlMoveMemory() will copy a block of an exact, speifiec size.

ReadProcessMemory and WriteProcessMemory can be used as well.
