The CeOpener Experience: Tapping into Sharp Brain's WinCE desktop

Roy Chan
Guest Reviews | April 7, 2020

This article is a companion to my review of the Sharp Brain PW-A7000, if you haven't seen my review and are not familiar with the PW-A7000 I suggest familiarising yourself with the Sharp Brain and its software limitations first.

Review: Sharp Brain PW-A7000

In its default state, the Sharp Brain excels as a Japanese language dictionary, but for the inquisitive Windows CE user, the custom Japanese language shell masks many of the expected Windows CE features and functions. Despite this, there exist a few programs that can tap into the Windows environment of the Sharp Brain electronic dictionary unit. These programs allow you to easily recover much of the functionality that a typical Handheld PC user would expect to see in the device.

  1. Task Switcher, a taskbar extended from the lower left of the screen, allows access to Settings, Control Panel, My Device, and any item in the Add App's list. There is also a TTFpatch function which changes the windows system font to English, essentially converting some of the menu and commands to English words.
    Figure 1: Task switcher, before running the ttfpatch, where fonts appear horizontally


  2. TestCE is a slim windows dialog offering access to LCD back light, sub-panel back light, sound volume and MR sensor adjustments, as well as a start button, control panel and windows explorer. One can even install cab files. The catch is that, no programs will appear on the start menu, even if you successfully install any Windows CE or Pocket PC programs. The only way to execute them is by directly double clicking the .exe from inside Windows Explorer.

  3. Selector when executed, hides in the background, accessible by pressing Convert button on the keyboard (4th from the right, top row). It is a three-tab'd side window that slides in from the right, pushing a third of the main display away.
    Left and right arrows cycle through the three tabs, displaying 1/currently running app's, 2/Appendable list of app's and 3/settings for hardware customisation and exiting Selector.

  4. Finally, CeOpener.

Of the four app's, I prefer this as it offers a full windows CE desktop, with the usual Start key, taskbar and running app's tabs; and it is CeOpener that I now focus on.

By default, My Device and Control Panel icons appear on the desktop. Touch-and-hold anywhere on the desktop, to pull up the three item menu with the following: Arrange Icons, Add Shortcut and Customise Desktop

The Customise Desktop item allows one to add shortcuts on the desktop to the Brain's 'NAND3' and 'SD card' storage locations.

Once you have downloaded CeOpener, you must rename the executable to AppMain.exe. Next, make a zero-byte dummy file named Index.bin and place it next to the executable. App's that you need to add to the Brain must each be contained in a folder named identically to the app itself, and copied into a folder named APULI located at the root of a micro SD card (APULI are three Japanese Katakana characters, literally meaning 'applications').

NOTE: you may want to ask; for those who didn't have or know Japanese IME, how do you name a folder with those 3 square boxes? In my case, I unzipped the ceOpener content using a regular PC and found a Japanese readme file. Opening the file reveals instructions to install, you just need to copy the text to Google translate to get an idea about using the 'APULI' folder. Find them, copy , make a folder in your SD card and paste in the content to get the folder.

This renaming-and-putting-a-zerobyte-file-into-a-samename-folder procedure has to be applied to each and every app which you want appear in the default "Add App's" list. This allows you to create a base set of programs that will enable you to launch a CE desktop environment. Any other Windows CE app's do not need to reside in the APULI folder once you successfully get the desktop up and running.

Once you have setup the correct folder structure, and inserted the SD card into the Brain, a reboot will enable the device to recognise the app folders, and a list of the app's show up in the Add App's page. At this point you have the option to leave the 'APULI' folder on the SD card or copy it to the NAND3 partition (using any file manager like windows explorer or CeCMD).

In the middle of the top bar in app's list, a two-character menu toggle displays the list of app's saved in NAND3, if any.

Figure 6: List of app's added

App's that I tried with the renaming method and copied to the 'APULI' folder and worked as expected were:

  1. Declock
  2. Tombo
  3. WR-Tools ResInfo
  4. CeCMD
  5. UltraG
  6. Minute Mascot
  7. CeProcess
  8. Test CE
  9. Selector
  10. Taskswitcher
  11. CeOpener

I have yet to try copying other app's to the APULI folder to see if they worked the same way. I won't go into detail using the above app's, however slowly but surely that nostalgic Windows CE desktop is starting to resurface.

Loading CeOpener makes everything a lot easier, because you can assign shortcut key combinations to execute app's located elsewhere on the micro SD card. You can even put shortcuts on the desktop itself. Which is my preference for using CeOpener.

At this point, it is suggested that you perform some translation steps on the main user interface. Starting from the Home screen, click on the Add App's icon (rightmost item in the second row) and it brings up the list of app's copied earlier to 'APULI' folder.

Figure 8: Note the folder with Japanese characters, that's where the renamed executables reside

Load Taskswitcher, click on the last icon to reveal a menu, and then run 'TTFpatch'.
This is needed to load up MSGothic fonts so that the menus and icon texts could be displayed in proper Japanese characters and English words, else you will only see square boxes instead of legible words. Not all texts and menu items will however be translated into English, but it makes the system considerably easier to use.

You may then exit Taskswitcher, or just leave it running in the background.

Next, click on 'CeOpener' and a prompt will says 'Please Wait'. 3 seconds later you hear that familiar Windows startup sound, and voila! I guarantee a smile on you face as the familiar START button and taskbar appear, together with a desktop wallpaper.

The Start button opens a menu with 8 items in Japanese, they are:

  1. My device - brings up Windows Explorer
  2. Control Panel - as we know it, with most of its applets appear here
  3. Run... - opens the run dialogue
  4. Programs - will extend the menu to display app items added to APULI folders
  5. Plug-ins - opens up a new menu with 4 items, again in Japanese
  6. Customising CeOpener
  7. Closing Sharp Simulator (the Sharp's default dictionary)
  8. Exit (the Windows Desktop)

Figure 9: The Start menu opens by clicking that button on the bottom left corner. A shortcut key can also be bound to it, in my case, FullSearch (button next to the On/Off button. The fourth item on the start menu displays the list of renamed app's in APULI folder

On the next menu are Input switch settings, plug in keys binding, openershot settings and power options.

Input switch settings allows you to enable or disable a) use sub-display for input, b) full use of sub-display for 2nd generation Brains and , c) disable input switch functions when Dictionary is in-focus. Plug in keys binding allows you to assign commands or key combinations to most of the hardware buttons (and a few touch keys on the left of sub-display), over-riding the default presets. As mentioned in the previous paragraph, you can choose to enable or disable personalised key-bindings whether or not 'Sharp Simulator' is in-focus.

With exception to On/Off, S-Jump, Back and Enter, all the hardware buttons can be assigned with two key bindings, with and without a Function key combination.

Figure 10:
Fifth item Plug ins access settings for input switches and key bindings

The alphanumeric buttons are also assign-able with key bindings, except in most use cases you won't need to do that.

Openershot settings lets you set the default folder to save screenshot files. By default, a 'screens' folder is shown, but if you intend to use that, be sure to make a folder with that name on the SD card, or you will receive an error message when you execute the screenshot key(s). What keys? Keep reading!

Finally Power options allows you to adjust back light level, CPU speed, and choose whether the unit suspends, dims the screens or switches on upon opening the display lid.

The next menu, Settings for CeOpener brings up two items:

  1. CeOpener settings - there are three tab pages, the first one where you select a font size for icon texts and menu items, change the colour scheme and background wallpaper for the desktop.
    Figure 11: Sixth item opens settings for ceOpener > Additional options

    (If you go to CeOpener folder, there is a 'Colors' folder with some .dat files, these are preset colour settings for the taskbar, and you can always create personalised schemes.) The second tab page allows for 4-level adjustment of icons transparency on the taskbar. The third tab page is where you set the windows sound effects. The first two, Starting and Exiting windows are pre-enabled by default.
  2. CeOpener key bindings - is a dialog box for you to assign key combinations to:-
    1. CeOpener volume up, volume down, start button, hide taskbar, Dictionary in-focus, switch tasks
    2. Inputswitch - for one bit alpha, one bit numerals, one bit symbols, one bit hiragana, two bit numerals, two bit symbols, comma and period.
    3. openerpointer - activates the mouse pointer onscreen, pointer click, and toggle (works like click-and-hold)
    4. openershot - screen capture

Note: some of the above input switches are pre-assigned with key combinations, which may be modified according to one's own preference.

Key bindings are automatically saved to a file named keybinding.key. This can also be exported as a backup to any other storage location, for later restoration, just in case. Knowing that a lot of customisation could be done catering to one's liking, the procedure of replacing deleted batteries is rather frustrating. The only way to circumvent this shortcoming is to plug-in external power while replacing the batteries; which kept all of my settings intact. Another option is to use regedit.exe to export the system registry beforehand, and restore it back just in case the inevitable happens.

Now for the interesting part.

If you intend to make use of the unit's hardware keyboard to do some serious typing. Beware! There being no spacebar, comma, period and - as mentioned in my preliminary review of the Sharp Brain - while Sharp did include a space button in their third and fourth generation models - typing in English is near impossible as a result.

The biggest surprise CeOpener gave me was that, the hyphen button which originally required the S-Jump key press combination to insert a space, no longer works. In fact, the Description button acts like a space button as well. The hyphen button now needs a Function key press together to generate that hyphen. All these changes because of CeOpener.

CeOpener also modifies some other key combinations:

  1. Description = start menu
  2. PageUp = period
  3. PageDown = comma

So with some persistence ad trial and error, I've managed to make most of the usual Windows combination keys come alive.

Installing other Windows CE app's

The Wceload.exe and Cabinst.exe installer runtimes do no install cab files successfully every time. After some frustration, I finally found that the easiest way was to install those app's on another Windows CE machine, and then transfer the whole program folder (with contents) to the micro SD card before launching .exe files directly.

After some testing, here is the list of the programs that I could run properly using this method:

  1. Declock
  2. CECMD
  3. TCPMP
  4. Minute Mascot
  5. CeProcess V
  6. UltraG
  7. uBook
  8. SpreadCE
  9. Aima Date Memo
  10. ListPro
  11. Tombo
  12. Pword
  13. Pocket Paint
  14. Pocket Artist
  15. One man and a cat doodler
  16. WR-ResInfo
  17. iTaskmanager
  18. TRE
  19. JR-Train
  20. FloatMe
  21. JotKbd
  22. KnaPiano
  23. Mobipocket Reader
  24. Calc98
  25. AClock
  26. JWPce
  27. JFC

Similarly, using the same technique it was possible to get some Pocket PC app's and games to run smoothly, including:

  1. Aqueball
  2. Balloons
  3. ICBM
  4. Bejeweled2
  5. Sudoku
  6. Tetris
  7. Minesweeper
  8. Shift
  9. Traffic
  10. ChainReaction
  11. Hexavirus
  12. Loderunner Lite
  13. Xenix
  14. Pipes
  15. mBoxman
  16. Battleship
  17. Blocks
  18. Mastermind
  19. warehouseguy
  20. ChessGenius

I am still trying to get Yamace to run Gameboy ROMs, but to no avail as it keeps crashing with GXOpenDialog errors. CeOpener does not attempt to resolve the issue of PIM. PIM functions (contacts, calendar, tasks and email) are not available at all on the device, as the application files, DLLs, databases and other Windows CE components are missing. It is however not out of the question that there is this hope that other tech-savvy fans may be able to figure out what is required and get these - and other other CE app's to run. Who knows, someone may even get it to sync with a PC!
