Geo Ster authored* Currently the BIOS only writes to scratchpad and some very few mysterious addresses that don't seem to do anything. However it is important to know when it will try to write to DMAC for example so we can implement it. So instead of writing anything and uncontrollably into a single large buffer let's make an if-else with all the known addresses and how to handle them. When the BIOS tries to write somewhere new we will be notified immediately. * Also rework the disassembly logger to use C FILE* since these are faster then std::ofstream. Normally I wouldn't care about this but in our usecase which is very performance sensitive, it makes a noticeable difference.
