However, the 0.139u1 version exists in a specific legal gray area known as "abandonware" among some hobbyists. Because many of the games on the 0.139u1 list (particularly obscure titles like Mini Boy 7 or Mega Double Poker ) are no longer commercially exploited by their original rights holders, the ROMs are widely traded. Nonetheless, you should research your local copyright laws before downloading any ROM set from the internet.
