A new GameBoy utility is released called gbdelogo. This program is very usefull to GameBoy programmers if you want to publish your work. For more information, here is the complete text of the enclosed text file: gbdelogo is a utility that can destroy or restore the Nintendo logo data header in a GameBoy ROM. It does not change any other headers, including the ROM's checksum. The real GameBoy hardware requires the 48 bytes of the logo header to be exactly correct, or the ROM won't run. However, these 48 bytes are copyrighted and protected by Nintendo, and distribution of public domain ROMs that have this intact data is usually not allowed. Fortunately, most emulators (and ROMs) don't care if the logo data (or the ROM checksum) is intact, and ROMS without a valid Nintendo logo will usually run perfectly. It is therefore recommended for public domain developers to distribute their public domain GameBoy ROMs without the copyrighted Nintendo logo data. The source file (gbdelogo.c) can be compiled to any POSIX-compatible target. A precompiled Win32 commandline executable is already enclosed. You can download this utility in the GameBoy Utilities section. Thanks to a anonymous programmer for the news.
