Hi! I've just released a 3DS build of
Headcannon Game Engine. I wanted to make mention here, but since I don't want to SPAM this thread, you can find out more in
this thread
Also, though, I'll share this:
I've added buffered read/writes to SDMC in my own personal build of ctrulib to greatly speed up multiple sequential, short reads/writes. You can get the modified SDMC source file
here. I'm not sure if it's the best method, but it works, and if anyone responsible actually wants to add it to the official ctrulib, feel free. I would appreciate credit for any usage, though
Incidentally, I had added chdir too, but that was officially added to ctrulib before I was ready for posting, so I've merged the official method into my source. As far as the public official source goes, this should be up-to-date
