This file lists every third-party piece in Delve with its author and licence, and carries the notices that the libraries linked into the ROM, the libraries bundled in the browser version (https://eightyfour.ca/delve/play/) and the libraries in the Android version ask for. The art and music are the same in all three versions.

The default ARM7 core: Copyright (c) 2023 Antonio Niño Díaz, zlib licence (the same terms as above). libnds includes FatFs by ChaN, under a BSD-style licence that needs no attribution in binaries; its terms: FatFs License FatFs has being developped as a personal project of the author, ChaN. It is free from the code anyone else wrote at current release. Following code block shows a copy of the FatFs license document that heading the source files. /*----------------------------------------------------------------------------/ / FatFs - Generic FAT Filesystem Module Rx.xx / /-----------------------------------------------------------------------------/ / / Copyright (C) 20xx, ChaN, all right reserved. / / FatFs module is an open source software. Redistribution and use of FatFs in / source and binary forms, with or without modification, are permitted provided / that the following condition is met: / / 1.

FatFs is mainly intended for embedded systems. In order to extend the usability for commercial products, the redistributions of FatFs in binary form, such as embedded code, binary library and any forms without source code, do not need to include about FatFs in the documentations. This is equivalent to the 1-clause BSD license. Of course FatFs is compatible with the most of open source software licenses include GNU GPL. When you redistribute the FatFs source code with changes or create a fork, the license can also be changed to GNU GPL, BSD-style license or any open source software license that not conflict with FatFs license. 4. crts, the startup code (BlocksDS).
