As far as I know, "Xboo" was a "brand" of sorts for no$gba developer Martin "nocash" Korth's boot loader cable designs. At the time, Xboo for GBA competed with the mass-produced MBV2 cable for GBA multiboot.

160p Test Suite is a port of Artemio Urbina's 240p Test Suite to Game Boy Advance. It has two goals:

1. Evaluate TV sets and video processors for ability to handle retro console video signals.
2. Turn a game console into a test signal generator to help in calibrating the black, white, and color levels and geometry of a display.

The port to GBA was originally requested by Extrems for testing Game Boy Interface (GBI), a Game Boy Player Start-Up Disc replacement app for Nintendo GameCube. It has since been used inside Nintendo, as reported by Kyle Orland of Ars Technica. It's been a long time since version 0.22 in November 2020, and even that was after forum.gbadev.org began to run into serious problems with its PHP installation.
