In "Mahjong Lemon Angel", the bug sometimes freezed (generated from v1.37) was solved. - The timing of the raster interrupt processing was brought close to the movement of a real machine. In the battle scene of "Tengai Makyou II", the problem that the background had shaken (generated from recent version) was solved. In the battle scene of "Dragon Slayer - The Legend of Heroes", the problem that the message window had shaken was solved. In "Ramma 1/2 Toraware no Hanayome", the problem that the upper part of the message window has blinked was solved.
