- Added "Show Audio Channel Graph" to "Info" menu. During game play Sound Volume Graph of each channel (6 channels + ADPCM + CDDA) can be displayed + Green graph ... Wave Memory sound Pink graph ... Noise sound Yellow graph ... DDA Sampling sound Orange graph ... LFO Modulation sound White (2nd right) ... ADPCM (CD Game only) Purple (1st right) ... CD-DA (CD Game only) * A channel whose graphs are "divided into left and right halves" is a channel that is playing with Stereo Sound * You can also switch the display position and hide it by pressing [9] and [0] (numeric keypad is disabled) on the keyboard - Fixed the processing timing of the built-in sound source (wave memory sound source). In "Xevious", an issue that sometimes caused the number of sounds to be low (occurred from recent versions) has been resolved. Also, I think that the tone has approached that of a real machine - Added "Size x5" to the "Screen" menu. * The enlargement process is heavy on older PC. In that case, please use full screen mode without overdoing it. By the way, when the distance to the display is short, "Size x3" size is more beautiful and still fits in the field of view, so it is recommended to play comfortably. "Size x5" is useful for small displays such as small 4K displays and when you want to play a little away from the display - Added "TV Scanlined 2 (Blur, Fast)" and "Non-Scanlined TV 2 (Blur for x4x5)" to the "Screen-> Mode" menu. If you are using a large window size or full screen, you can play on a large blurred screen if you use these at full HD or higher resolution. I think that this large blur is effective when playing on large LCD TV - Fixed an issue that the aspect ratio of the game screen display was slightly incorrect - The speed and timing were brought closer to a real machine. In "Quiz Tonosama no Yabou", resolved an issue (occurred from v2.51) that caused the screen to shake at the start of the quiz questions. In "Star Parodia", resolved an issue where the display of the rainbow scene before the first boss was a bit confusing (occurred from recent versions) - When using in a multi-display environment, coordinate correction processing is no longer performed even when the Ootake's window protrudes from the screen - With some PC environments, in full screen mode, fixed an issue that caused V-Sync to not synchronize well and left tearing at the top of the screen. If this doesn't work, try unchecking the "Screen -> V-Sync -> V-Sync Timing Adjust" menu - Organized the contents of "Audio" menu and "Setting->Audio" menu. The audio buffer amount is indicated in frame time units - Removed "Direct Draw" setting in "Setting->Screen" menu. From this version, only Direct3D drawing is supported - The Aero function is automatically turned off (display delay is reduced) when used with Windows7. In addition, the "Screen->Disable Aero" menu deleted in v2.88 has been restored - Fixed a bug that the tempo of the sound may not be stable for about the first second immediately after opening the game ROM image file with some PC environments - Fixed a bug that the game name was not displayed correctly when "&" was entered in the game name at the "Recent" menu - Other minor details have been modified and improved
