.Dd $Mdocdate$ .Dt RGBLINK 1 .Os RGBDS Manual .Sh NAME .Nm rgblink .Nd Game Boy linker .Sh SYNOPSIS .Nm rgblink .Op Fl t .Op Fl l Ar library .Op Fl m Ar mapfile .Op Fl n Ar symfile .Op Fl o Ar outfile .Op Fl p Ar pad_value .Op Fl s Ar symbol .Ar .Sh DESCRIPTION The .Nm program links objects created by .Xr rgbasm 1 into a single Game Boy ROM file. .Pp By default, HOME sections created by the assembler are placed in the 16KiB bank 0, and CODE/DATA sections are placed in any bank except bank 0. If your ROM will only be 32KiB, you can use the .Fl t option to override this. .Pp The arguments are as follows: .Bl -tag -width Ds .It Fl l Ar library Include a referenced library module created with .Xr rgblib 1 . Note that specified libraries will be included only if needed\(emthat is, if a SECTION from a library is referenced by an object file. Only the relevant SECTION will be included, rather than the entire module. .It Fl m Ar mapfile Write a mapfile to the given filename. .It Fl n Ar symfile Write a symbol file to the given filename. .It Fl o Ar outfile Write ROM image to the given filename. .It Fl p Ar pad_value When padding an image, pad with this value. The default is 0x00. .It Fl s Ar symbol ??? .It Fl t Write a tiny .Pq 32KiB ROM file. This forces all DATA/CODE sections to be of type HOME, and increases the HOME section size from 16KiB to 32KiB. .El .Sh EXAMPLES All you need for a basic ROM is an object file, which can be made into a ROM image like so: .Pp .D1 $ rgblink \-o bar.gb foo.o .Pp The resulting bar.gb will not have correct checksums .Pq unless you put them in the assembly source . You should use .Xr rgbfix 1 to fix these so that the program will actually run in a Game Boy: .Pp .D1 $ rgbfix \-v bar.gb .Sh SEE ALSO .Xr rgbds 7 , .Xr rgbasm 1 , .Xr rgbfix 1 , .Xr rgblib 1 , .Xr gbz80 7 .Sh HISTORY .Nm was originally written by Carsten S\(/orensen as part of the ASMotor package, and was later packaged in RGBDS by Justin Lloyd.
