During system boot, the system-font is loaded by [[NS]] to LINEAR-memory(in the original 0x14000000 vmem region) which always gets allocated at SYSTEM_memregion+0. Due to it being located there, all of this is GPU accessible. The [[BCFNT]] is loaded from the font title for the system region into that memory. During loading, the font-data is modified: the magic-num at fontdata+0 is changed from "CFNT" to "CFNU", and all file offsets are converted to addresses in this allocated linearmem. Processes can get the sharedmem_handle+vaddr for mapping the sharedmem for this via [[NS and APT Services|APT:GetSharedFont]]. | During system boot, the system-font is loaded by [[NS]] to LINEAR-memory(in the original 0x14000000 vmem region) which always gets allocated at SYSTEM_memregion+0.

| This is leftover data from decompression operation. During the font loading process, compressed data is loaded to <code>sharedmem + 0x332000 - compressed_size_aligned_to_4</code>, and then is decompressed to <code>sharedmem + 0x80</code>. Compressed data at the end that doesn't get overwritten by decompressed data remains in the shared memory | |||

Some of these characters are used for tutorial message boxes and notifications; they can also be generally used in [[Mii]] names, [[SMDH|application titles]], etc. | |||
Most of these originated in the "icons" tab of the DS's standard software keyboard, and were extensively used in its firmware UI. | |||
