Kenka Bancho 4 staves off all comers, leaping straight into first place for the Japanese video game chart for February 22 to 28.

The game is a schoolyard scrapper, as players challenge other delinquent pupils for their badges and the right to become the toughest schoolkid in the land.

Sequel to the 2008 Japanese release of (almost) the same name,  Super Robot Wars OG Saga: Endless Frontier Exceed offers more of the same robot-battling, over-the-top and tongue-in-cheek anime-styled role-playing.

Also new in the chart this week is Minna no Tennis Portable. Its makers, Clap Hanz, have developed each entry in the Minna no Golf / Everybody's Golf / Hot Shots Golf series, other than the first, and all those games are known by a different prefix in Japan, Europe, and North America respectively.

Everybody's Tennis was a PlayStation 2 game brought out in 2007 and here receives a PSP version fresh for the Japanese market. Other than recent PSP mini-game title Minna no Sukkiri ("Something for Everybody"), it's only the third non-golf title that the putting experts have produced.

Shiren the Wanderer makes his way onto the Nintendo DS after an excursion to the PSP earlier in the year, this time in the fourth iteration of the monster-slaying, quest-completing series.
