Game Boy Interface is a free alternative to the Game Boy Player Start-up Disc software. It still requires the Game Boy Player hardware.

Game Boy Interface is currently available in three different editions: Standard, Speedrunning and High-Fidelity.

Overview

The standard edition is ideal for sample-and-hold displays (LCD, OLED). By default, it emulates some aspects of the color and sound of the original handheld. With a Broadband Adapter and USB Gecko in hand, it can be used as a small Game Boy Advance development kit.

The speedrunning edition is ideal for impulse displays (CRT, 1ms MPRT LCD, Plasma). It attempts to be a non-controversial improvement for speedrunners. To ease transition, it can be configured to closely mimic the Game Boy Player Start-up Disc.

The high-fidelity edition is ideal for use with the Open Source Scan Converter, XRGB-mini Framemeister, or using solely a video capture device and software processing. Given the right setup, it can offer audiovisual quality comparable to emulation on newer platforms. It is less than suitable for direct display connection, with some exceptions.

All editions can emulate the color and sound of the original handheld if desired.

TL;DR

Open Source Scan Converter? → gbihf-ossc.dol+cli, gbihf-carby.dol+cli or gbihf.dol

XRGB-mini Framemeister? → gbihf-xrgb.dol+cli or gbisr-xrgb.dol+cli

Nintendo GameCube Component Video Cable? → gbihf-cmpv.dol+cli, gbihf.dol or gbi.dol

GCVideo-DVI/HDMI? → gbisr-gchd.dol+cli or gbi.dol

Anything* else → gbisr.dol or gbi.dol

If you have something truly exotic, hopefully you don't need a tl;dr.

GBA-as-controller

Turn your Game Boy Advance into a Nintendo 64 or Nintendo GameCube Controller using the Game Boy Advance Cable.

Rumble is supported using the following Game or Option Paks:

• Drill Dozer
• Nintendo DS Rumble Pak
• Nintendo DS Slide Controller
• WarioWare: Twisted!

e-Reader dot codes and multi-bootable ROMs are provided in the extra package for untethered use from Game Boy Interface.

It also prolongs battery life over the Game Boy Player Start-up Disc with power saving trickery, while maximizing performance.

GBA dumper

Holding Start + Select in the Game Boy Player while the Game Boy logo is visible will grant you access to a dumping utility. From there, you can dump your GBA BIOS, ROM, or save data.

An SD Card and SD Card Adapter is required. In the speedrunning edition, this is substituted by a built-in GBA ROM checksumming utility.

TAS playback

Game Boy Interface has a built-in movie playback feature, allowing for the console verification of GBC-on-GBA and GBA tool-assisted speedruns, all without hardware modification.

A few console-verified movies are included in the extra package. An SD Card and SD Card Adapter is required.

Configuration

Using Swiss

When loading a .dol file, Swiss first look for a .dcp file. This file contain a limited set of options that can be interactively changed before starting Game Boy Interface. This set of options can be expanded upon, but is limited to 16 options with 8 choices of 31 characters. Note that the default shown positions don't represent the default settings.

For a more permanent or advanced configuration, a .cli file can be used. This file contain command-line arguments on separate lines.

A list of options and example configurations can be found in the subpage for each edition.

Using wiiload

Game Boy Interface can be reloaded using its built-in wiiload server with command-line arguments passed on to the wiiload client.

New overlays can also be uploaded in this fashion.

Other

The contents of a .cli file can be appended to a .dol file to form a .dol+cli file. The file must end with a blank line due to the hacky nature of this method.

When using a game save exploit, the resulting .dol+cli file can be converted to a .gci file using dol2gci.exe from the extra package.
