Hardware-wise the big winner was unsurprisingly the DS Lite, which topped 600,000 units sold for the month. These sales accounted for almost 56% of hardware sales for the month. This puts the life-to-date sales for the handheld at 17,152,000 units (this number includes the DS Phat). Meanwhile, Sony's PSP had a strong month as well, topping 120,000 units sold in May.

In software news, the newly released PS1 remake, Final Fantasy Tactics: Shishi Senso for the PSP, topped sales charts for May. Following shortly behind was another handheld Square Enix tactical RPG, Final Fantasy XII: Revanant Wings for the DS. After these two handheld games was Super Paper Mario for the Wii. Rounding out the rest of the top five were Wii Sports and Momotarou Dentetsu DS: Tokyo & Japan.
