Sorry, I'm new so my terminology regarding Disassembly/Decompiling/Debugging is sort of shoddy. I opened up a fire red idb I got on Github, and while it will show me a lot of the memory, it won't show me .thumb(unless it's not supposed to..?). Also, opening the Emerald idb won't show me anything but the text you can view to your right in a hex editor. :| I'm stumped. Furthermore, whenever I open the idb in IDA, it says that some of the memory may be invisible, or something to that effect.
Sorry. I was trying to ask about IDA, the popular Disassembler that everyone around here seems to use. I wanted to know what I should do if IDA tells me that GDB(I think that's what it's called) cant view the memory, thus parts of it may be invisible to me.
