It is a single instruction which multiplies a 4D vector by the 4x4 matrix held within the back-bank of FPU registers, '''XMTRX'''. This article will teach you how to leverage this god instruction for FP performance gainz and introduce you to several example scenarios that have y..." current

This gives us an invaluable tool for getting quick and immediate feedback on how well a given C or C++ source segment tends to translate into SH4 assembly, offering a li..."

While it lacks the full standalone GAME mode featured in the first-party VMUs, preventing it from playing minigames, it does provide equivalent functionality while plugged into the controller and even has a builtin firmware offering several features when used in standalone mode. === Features ==..."

• 08:2108:21, 14 October 2023 diff hist −4‎ Useful programming tips ‎ I'm sorry, but the way this is worded is just not quite correct. He's talking about aspects of the processor, but he's making it sound like modern software PARADIGMS and practices don't apply to DC, when in reality we have C++20 and even all of the async, concurrent crap used in multicore working just fine. current
