Assembler, and C, I would be working with C++ but it's too high-level(lookup the term if you don't know what I mean by "high-level"). I need to write a memory management system before I have a use of working with C++. I.e I need to write new, and delete methods. I can't just have it allocate and write to random areas, it could be invading other parts of the OS's, or another program's memory region.
@TropX: I try to keep information about be private because I don't want to be rapppppped(or identified by people in my social life or school, I'm not exactly proud of what jetamay has done, lol. Jetamay used to be flamming emo back in the old days of MPGH).
