+.\" ITEM
+.It Fl j
+Set the non-Japanese region flag: [0x14A] = 1.

+.It Fl k Ar licensee_str
+Set the new licensee string ([0x144\(en0x145]) to a given string, truncated

+.\" ITEM
+.It Fl m Ar mbc_type
+Set the MBC type, [0x147], to a given value from 0 to 0xFF.

+.It Fl p Ar pad_value
+Pad the image to a valid size with a given pad value from 0 to 0xFF.
+.Nm
+will automatically pick a size from 32KiB, 64KiB, 128KiB, ..., 8192KiB and
+give a warning thereafter. The cartridge size byte ([0x148]) will be changed
+to reflect this new size.
+.\" ITEM

+Enable quiet mode, suppressing all text except errors.
+.\" ITEM
+.It Fl r Ar ram_size
+Set the RAM size, [0x149], to a given value from 0 to 0xFF.
+.\" ITEM
+.It Fl s
+Set the SGB flag: [0x146] = 3, and set the old licensee code: [0x14B] = 0x33.
+.\" ITEM
+.It Fl t Ar title
+Set the title string ([0x134\(en0x143]) to a given string, truncated to at
+most 16 characters. It is recommended to use 15 characters instead, to avoid
+clashing with the CGB flag (
+.Fl c
+or
+.Fl C Ns
+).
+.\" ITEM
+.It Fl v
+Validate the header and fix checksums: the Nintendo character area
+([0x104\(en0x133]), the header checksum ([0x14D]), and the global checksum
+([0x14E\(en0x14F]).
+.El
+.\" SECTION
+.Sh EXAMPLES
+Most values in the ROM header are only cosmetic. The bare minimum requirements
+for a workable image are checksums, the Nintendo logo, and (if needed) the
+CGB/SGB flags. It is a good idea to pad the image to a valid size as well
+("valid" meaning a multiple of 32KiB).
+.Pp
+The following will make a plain, no-color Game Boy game without checking for
+a valid size:
+.Pp
+.D1 $ rgbfix \-v foo.gb
+.Pp
+The following will make a SGB-enabled, color-enabled game with a title of
+"foobar", and pad it to a multiple of 32KiB. (The Game Boy itself does not
+use the title, but some emulators or ROM managers might.)
+.Pp
+.D1 $ rgbfix \-vCs \-p 0 \-t foobar baz.gb
+.Pp
+The following will duplicate the header (sans global checksum) of the game
+"Survival Kids":
+.Pp
+.D1 $ rgbfix \-Cjsv \-k A4 \-m 0x1B \-p 0xFF \-r 3 \-t SURVIVALKIDAVKE SurvivalKids.gbc

+.\" SECTION
+.Sh DESCRIPTION
+The

+program links objects created by

+.Pp
+By default, HOME sections created by the assembler are placed in the 16KiB

+Include a referenced library module created with

+Write a tiny (32KiB) ROM file. This forces all DATA/CODE sections to be of

+.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 (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
