- The operation part of the joypad is brought close to the operation of the actual machine. In "Magicoal", the problem that two people play could not be played was solved.
- The timing of the operation is brought close to the operation of the actual machine. In "The Legendary Axe II", the problem that the screen was dark one frame at the start demo was solved.
- "HES BigAudioBuffer (Frame Skip)" was added to the Audio menu. When this is checked, if the HES file (program for PCE's built-in sound, extension is ".hes") is opened, it is started with BigAudioBuffer mode(sound is delayed but stable processing with a large buffer and omitting the drawing).
- Additionally, a detailed part has been improved and corrected.
