The speed and timing were brought close to the movement of a real machine. In the start demo of "City Hunter", the problem that the lower side of the screen has fallen into disorder by one frame (generated by v2.40) was solved. I think that the timing has approached a real machine in even other games.
"Force V-Sync (All Hz)" was added to "Setting->Screen" menu. When the check is put in here, the V-Sync setting is permitted regardless of the PC display environment. Use it with an old video card etc.
Additionally, a detailed part has been improved and corrected.
