1.3 Voyage 200 (also V200 and Voyage 200 PLT)

No emulators exist for WM.

1.4 TI-89 and TI-92 series

These are, after the TI-84 series, the most widely sold TI calculators. Again, don't forget that this series is the way to go (and NOT the more widely sold TI-84 series!) if you want something above the high school level. Do read the related Wiki / ticalc pages.

1.5 TI-86

This calculator (released in 1997) is partially compatible with the TI-85 (which it replaced) and is also supported by VirtualTI-89Pocket.

1.6 TI-83, Plus and Plus Silver Edition

Two of these calculators, the TI-83 and the TI-83 Plus (released in 1996 and 1999, respectively) are supported under WM; the latest (2001) model, Plus Silver Edition (which has nine times the available Flash ROM and over twice the processing speed of the Plus), isn’t.

The changes between TI-83 and the TI-83 Plus were pretty big; for example, the latter already allowed for ROM updates.

1.8 TI-85 (and THIS)

This model has been replaced by TI-86.

2.1 Getting calculator ROM’s

Both the desktop and the Windows Mobile-based emulators require the original ROM of your calculator(s) to be present. It’s easily extractable using the desktop-based ROM extraction tools (it’s also built-in into VTI, the most important desktop-based emulator). However, if you DO have the original device, you may want to choose downloading the original ROM’s right from the homepage of TI itself.

You will most probably need the TI-89 ROM download (currently, it’s “TI-89 Operating System v2.09”; click the Download icon on the center right). It’s also linked from HERE. Just put the resulting os.89u file in the home directory of your desktop / Windows Mobile version. That is, with the desktop version, just copy it into the directory you’ve uncompressed the emulator to; with the Windows Mobile version, you’ll need to copy it to <storage card name>\Program Files\VTI Pocket Emulator.

You can access the majority of the other, compatible ROM’s on TI’s other pages (see the related row in the Comparison Chart) if you really need compliance with those older and/or less capable models (if not, just stick with the 89 – it’s the best, still supported model). If you need one of the TI-82, 83 and 86 ROM’s, you can also get them from other pages; for example TheOldComputer.com’s ROM download page. Note that you will NOT want to use the TI-85 ROM in there – it won’t work (not that it would be a problem: the TI-85 is superseded by the supported & compatible TI-86). M.E.S.S., another desktop emulator for (along with several other models) the TI-81, 85 and 86 isn’t able to use this ROM either. Also note that the TI-99 also listed in the TI section is NOT a calculator ROM but that of a very old home computer, the TI-99/4A.

All ROM files must be copied to the home directory of the emulator; with both the desktop-based and the mobile one. With the TheOldComputer.com package, you’ll, naturally, need to decompress them first.

Note that you won’t need for example the TI-84 Plus ROM (also linked from the ticalc.org TI-84 Plus page) because not even the desktop VTI support the new 84 (Plus). The same stands for the latest 89-series model, the TI-89 Titanium: its ROM doesn’t work under any emulators either (it’s identified as TI-92+ by both the desktop and the WM emulator and is refused to be loaded). Finally, other current models aren’t supported either.

2.2 Emulation on Desktop Windows

You MUST learn how the emulator must be used under the desktop Windows operating system if you will ever want to import any third-party application into your Windows Mobile-based emulator or want to export your own programs typed (tapped) directly into the emulator in easily maintainable, direct exports.

The best emulator available for the desktop is Rusty Wagner’s free Virtual TI v2.5 beta 5 (linked from the main page HERE; alternate download HERE), which is compatible with TI-82, 83, 83 Plus, 85, 86 and 89.

(Note that you won’t want to download the Virtual TI-89/92(+) Emulator v1.01 Beta (it doesn't find the ROM image in the same directory) or the Virtual TI v3.0 Alpha, unless you want a TI-73 / TI-83 Plus emulator only.)

Just download the ZIP file and, after copying one (or more) ROM files in the same directory (if you don’t want to use the app to extract a ROM image from your connected calculator), start vti.exe.

A calculator image will come up (showing the face of a TI emulator, depending on the available ROM images in the home directory). If it’s the wrong emulator (you’d like to emulate another calculator by changing the ROM image) either press F12 or right-click the image and select Set calculator / ROM version as can be seen in this screenshot.

A dialog box will be shown, showing what ROM versions are available. Just select the one you’d like to use (for example, in this screenshot, I’ve selected the TI-89) and click OK.

After changing the ROM, the skin will immediately change and the calculator boot in as can be seen in here. You will want to raise the (virtual) contrast by repeatedly clicking the ("diamond") button and, then, clicking the + button. To make this faster, use the Ctrl key (it’s a shortcut for the diamond key) on your desktop keyboard while depressing + (or -, if you want to decrease the contrast) on your keyboard. BTW, the diamond key will always result in invoking the functionality printed in green on top of most buttons. The yellow 2nd button, , (also in the top left) will do the same, but with the yellow labels (second functionality) printed on top of most buttons (note that the desktop PC keyboard uses the Alt shortcut for the 2nd button).

Now, you can start to do some serious work. If you already know how to operate a TI-89 (from now on, I only show how it can be operated; other models are, fortunately, pretty similar in operation), then, you will only need information on how files / programs can be transferred between the operating system and the emulator itself. If you’re a newbie, on the other hand, you may want to download the official TI-89/92 manual / guidebook from HERE. It’s certainly a good read, but may be a little too much for a newbie, particularly because it discusses two series at once. Therefore, for basic tasks like program transfer and starting, you may want to prefer my tutorial below, particularly because, of course, it doesn’t discuss emulation-related questions at all. (Needless to say, the documentation coming with VTI is pretty useless for a newbie. The Windows Mobile port is even worse: it has absolutely no Windows Mobile-related documentation. That is, you won’t be able to learn anywhere – except for my current article – how you can import third-party / external programs to it.)

First, let’s see how file transfer is done from the desktop PC to the emulator.
