Publisher Konami has posted a net income of ¥4192 million ($52 million) for its first half of 2010.
This is a rise of 87.8 per cent over the prior half, which is primarily attributed to the release of the latest Pro Evolution Socer, Metal Gear Solid Peace Walker on PSP and slot machine Podium.
Revenues for the six months ending September 30 reached ¥115.8 billion ($1.43 billion), up 1.6 per cent on the second half of 2009.
The Japanese publisher claimed sales for PES (known as World Soccer Wining Eleven 2010 Aoki Samaurai no Chosen in its homeland) and Peace Walker had been "steady", and also celebrated the domestic performance of romance simulator LovePlusPlus.
Digital entertainment remained the company's largest earner, with health and fitness software and clubs not far behind.
The company predicted a net income of ¥22.5 billion ($279 million) for the fiscal year ending March 31 2011, and revenues of ¥285 billion ($3.53 billion).
