Ootake Ver2.86

PCE/PCE-CD模擬器 Ootake 發布新版，更新如下 :

- "Configure Open Button" was added to "Input-> Configure" menu. You can
    change the shortcut key for opening the game file ([O] key and [P] key) to
    any key.
  - "Configure" was added to the top of the "Input" menu, and the menu was
    tidied up. * However, this is still complicated. Although it may become
    next year, I will make a special form for controller setting.
  - "Adjust Old CD-ROM2 Speed (Super Darius)" added to "Setting-> Improve"
    menu. When this is checked, in "Super Darius", at the game start and the
    boss appearance etc., the CD access time is adjusted to the wait time
    equivalent to that of the first (old white machine) CD-ROM2 System. When
    this check is removed, the wait time will be as short as PC Engine Duo (
    default).
  - When a game for ARCADE Card is played, if Resume-Mode ("File-> Set Resume"
    menu) is set, if "CD-ROM-> Play with Non ARCADE Card" menu is executed,
    the bug that the game stopped (occurred from v2.85) was fixed.
    * I think that this is a rare case, but if this trouble makes it
      impossible to continue the game, please play the continuation from state
      save data. Or, please reset using [F1] key, load from backup RAM (save
      data in the game) and continue the game.
  - Additionally, a detailed part has been improved and corrected.

Wataroo 0.7.1.0

Watara SuperVision模擬器 Watara SuperVision 發布新版，更新如下 :

Added :

• Mouse cursor autohiding in Full Screen Mode.
• Super Divider audio enhancement feature.
• Waveform hardware checks to WaTest.
• List of detected joysticks now displayed after a manual rescan.
• XInput support.

Cleanup :

• Split 65C02 emulation into fetch and execute phases to fudge timing a little better.
• Pulse channels’ prescaler reset conditions adjusted to better match the hardware.
• Noise channel’s dividers were running half as fast as they should have been.
• DMA check in WaTest now performs transfers both to and from VRAM.
• Joystick auto rescanning would never trigger from a cold start if multiple joysticks were connected.
• Joystick auto rescan interval reduced from four to two seconds.
• Corrected a fairly embarrassing access violation when loading user button mappings.

melonDS 0.5

NDS模擬器 melonDS 發布新版，更新如下 :

Yup, there it is.





It's a recurrent theme in my projects that UI shenanigans are something I have trouble with. It's not that hard to make a UI, but making it cross-platform is another deal entirely. I want to avoid ending up with a different, separate UI per platform.

In the end, I went with libui, which is small and lightweight. I modified it to fit my needs.

The decision took a while though, and is one of the reasons why the release took so long to happen. Other reasons being, well, real life. My previous job is over, and hello job hunting again.


So this release features a new UI. It's not too new, but it removes the unneeded windows. Menus and video output are in the same window now, and the console window (the black window that spews nonsense) will be absent from release builds.

You can also drag-drop ROMs onto the window to run them. It is also possible to run ROMs via command line, but ATM when doing so melonDS will attempt to look for BIOS/firmware/INI in the directory the ROM is in.

If you play with your keyboard, you will need to remap your input, as different key codes are used (raw scancodes vs SDL scancodes).

Other than that, there are not a whole lot of changes emulation-wise. A few fixes, and the addition of antialiasing, as mentioned in the previous post.


Regardless, have fun.


The new UI library is incompatible with Windows XP or Vista, so there will be no such builds.
