* m_Do_Reset: split and (some) decomp decompiles: - my_OSCancelAlarmAll() - destroyVideo() * mDoRst::reset(): decompile, plus some supporting code * split DVD* functions to dvd.h * mDoRst::resetCallBack(): decompile * JUTXfb: split * JUTXfb: decompile (except for almost-matching ctor) Elaborates JUTVideo and some related stuff. Decompiles the following functions: - JUTXfb::initiate() - JUTXfb::createManager() - JUTXfb::common_init() - JUTXfb::destroyManager() - JUTXfb::~JUTXfb() - JUTXfb::JUTXfb(): *almost* matching up to regalloc * clang-format and extern label modifications Co-authored-by: Pheenoh <pheenoh@gmail.com>
