Use setvbuf and allocate a heap buffer on file access
This works around the default 1KB buffer that 3DS newlib has, which makes I/O slow. With this "hack" I mean, workaround, load times are reduced to 25% (around 3-4x faster), making the experience enjoyable. Level loading times around around 4-6 seconds (vs ~25s).
This is a hack, ideally some intermediate loading method should be added for consoles that do not have enough ram to load the entire datapack but have enough memory to load a significant amount of it (i.e. an LRU buffer cache or something).
Interesting workaround! Though I'm not quite sure if the o3DS has enough RAM left to fit some of the bigger files entirely in memory? Also do you mind if I steal this idea for my Wii port?
After playing a bit more, maybe I should cap the buffer at 512KB or so, or exclude ogg/ogv files. Theres a small 400ms freeze when the audio track changes.

The audio freeze is mostly due to the asynchronous load not being implemented yet.
