- The development environment of Ootake has been changed from "Visual Studio 2019" to "Visual Studio 2022". Along with this, even if you build(compile) with "Optimization ON", it will no longer be falsely detected by some antivirus software, so build with "Optimization ON" for public files (Ootake.exe) is now done from this version. I think that there are more PCs that can operate comfortably without processing omissions even on older PCs than the version released with "Optimization OFF".
- The volume balance of the ADPCM sound source has been brought closer to that of the actual device.
- When playing "TATSUJIN" in the overscan area display ([F12] key) environment, the dust display at the top and bottom of the screen (it also exists with the actual machine) has been suppressed. The PC Engine version of "TATSUJIN" has a narrow screen, but the enemy bullets are fast, so I feel that it is too difficult for people to enjoy it unless the overscan area is displayed. In addition, if you select the difficulty level EASY with the trick of "RUN while pressing SELECT on the title screen", I think that those who like the great transplant "Kyukyoku Tiger" and "Super Raiden" will probably enjoy it just right. If you check the "CPU-> Perform Sprite Limit" menu, it will be reproduced in the same way as the actual machine (garbage will be displayed when restarting after being killed).
- The processing related to raster interrupts has been brought closer to the operation of the actual machine. The problem that the drawing on the screen was disturbed in the demo scene of "Sol Moonarge" (occurred from v2.81. It was not fixed in v3.03) has been solved.
- Fixed a bug (occurred from v2.96) that sometimes "a very old version state save file" could not be read correctly.
- Fixed a bug that the game screen sometimes went black when the resume was restored when the stretch screen mode was changed when using the resume save ("File-> Set Resume" menu).
- Other small parts have been corrected and improved.
