A little background on who I am - I am a college student who in their free time is also an independent game engine developer for Xbox Series X|S, Windows 10 and Nintendo Switch. I am currently working on
two different open source engines both powered by DirectX 12 Ultimate (or NVN in the case of Switch). These engines aim to fill a couple of niches that I feel are open, including an engine architecture that replicates the HW architecture of old school bitmap based consoles as well as providing a GUI-less rendering engine for those who want to develop a game without the bloat of Unity/Unreal/etc....
A couple of things to note - Being a completely independent dev working on my engines in my free time, I am not officially affiliated with Microsoft/Xbox in any way. Nor do I currently have a devkit (my "devkits" are a DX12U capable PC, retail Xboxes with devmode enabled and a Switch capable of using fusee gelee), so if you have a question surrounding hardware, I can attempt to answer it using my knowledge of computers and officially released information,
but please take it with plenty of salt as I could be wrong.
