To run AlmostTI, you will need at least one calculator system ROM. AlmostTI does not include any calculator ROMs on its own, as they are intellectual property of Texas Instruments. You should place your own ROM, preferably dumped from the calculator you own, onto your internal storage. AlmostTI recognizes following ROM files (in upper or lower case):
TI85.ROM, TI86.ROM, TI81.ROM, TI82.ROM, TI73.ROM, TI83.ROM, TI83P.ROM, TI83SE.ROM, TI84P.ROM, TI84SE.ROM
TI-85.ROM, TI-86.ROM, TI-81.ROM, TI-82.ROM, TI-73.ROM, TI-83.ROM, TI-83P.ROM, TI-83SE.ROM, TI-84P.ROM, TI-84SE.ROM
For information on dumping a ROM from your own calculator, see here:

Wabbitemu, like all emulators, requires a ROM image. Wabbitemu includes an easy to use setup wizard that will help you create a ROM image for your TI.
More documentation can be found on the official website, http://wabbit.codeplex.com
*Please remember to read the ROM section below before downloading this application!
It will turn your phone or tablet into an exact replica of your calculator. The emulator will provide the same functionality and generate the same results as your real calculator. Being ported to Android means that it will always fit in your pocket, have a backlight, be rechargeable and also run faster.
You would be able to install applications by copying the App file to the internal memory of your phone, pressing the 'Back' button and selecting 'Install Application/Send File'.
Graph89 would be great tool for math, science and engineering courses in high school, college and beyond. Some of these calculators feature Computer Algebra System (CAS) having the capability to simplify and symbolically solve mathematical expressions.
Graph89 combines two powerful emulation engines which make it the only app in the Android Play Store to support the full range of TI graphing calculators.
1) TiEmu - http://lpg.ticalc.org/prj_tiemu providing support for the Motorola 68K family: TI89, TI89 Titanium, TI92 Plus, Voyage 200
2) TilEm - http://lpg.ticalc.org/prj_tilem providing support for the Z80 family: TI 83, TI 83+, TI 83+ SE, TI 84+, TI 84+ SE
!!! IMPORTANT !!!
Emulators are computer software which simulate a specific hardware. In order for the emulator to do anything useful it needs some software to run. The software that runs in your calculator (ROM) is copyrighted by TI, and as such, it can not be distributed by Graph89 or any other emulator for that fact.
This means that you will have to provide the ROM file yourself by extracting it from your own calculator. Transfer it to your phone, and then tell Graph89 where to find it. To extract the ROM you can follow the instructions from http://www.ticalc.org/programming/emulators/romdump.html and by using TiLPII from http://sourceforge.net/projects/tilp/files Google and youtube are also great sources of tutorials and help.
Wabbitemu http://wabbit.codeplex.com/ is also a great tool for extracting the ROM from your TI83/TI84
Supported ROM files:
TI89, TI89 Titanium, TI92 Plus and Voyage 200:
*.rom, *.89u, *.v2u, *.9xu, *.tib
TI83 Plus, TI83 Plus SE, TI84 Plus and TI84 Plus SE:
Firmware updates (*.89u, 9xu, *.v2u, *.8Xu) which are normally used to restore the operating system of your calculator can also be used as a ROM image.
Needless to say, you will be very disappointed if you purchase Graph89 without having the ROM file ready. You will just see some instructions and a blank screen.
Graph89 needs permission to look at your Android Account in order to generate a unique ID shown under F1/About. This works only for TI89/V200. Note that there is no internet connection required for this App.
TiEmu, TilEm and Graph89 have been developed independently of Texas Instruments and are not affiliated with TI.
Texas Instruments and TI are trademarks of Texas Instruments Incorporated.
An 8Xu (firmware update) file can now be used as a ROM for TI84+, TI84+SE, TI83+ and TI83+SE
Added support for: TI-83, TI-83 Plus, TI-83 Plus SE, TI-84 Plus and TI-84 Plus Second Edition using the TilEm2.00 engine.

The following mathematical functions are available:
polynomials, rational functions, trigonometric functions, inverse trigonometric functions, hyperbolic functions, natural logarithm, exponential function and all the possible combinations of them.
Best math tool for school and college! If you are a student, it will help you to learn calculus (analysis) and algebra!
Note: Mathematical analysis is a branch of mathematics that includes the theories of differentiation, integration, measure, limits, infinite series and analytic functions. It can be applied to physics, economics and engineering.
The integration of functions is facilitated by self-completion of statements, also expressions of the interpreter is very flexible and allows the inclusion of any function: even the most complex are recognized and interpreted correctly.
The main functions recognized are: abs(x), acos(x), acosh(x), asin(x), asinh(x), atan(x), avg(x1,x2,...,xN), ceil(x), combin(x,y), cos(x), cosh(x), e(), exp(x), fact(x), floor(x), lg(x), ln(x), log(x,y), max(x1,x2,...,mN), min(x1,x2,...,xN), mod(x,y), pi(), pow(x,y), rand(), sign(x), sin(x), sinh(x), sqrt(x), sum(x1,x2,...,xN), tan(x), tanh(x), toDeg(x), toRad(x).
The graph allows an accurate view of the trend of function at any point in the plane. You can zoom and pan through the classical gestures.
There is also a tool which can calculate the value of the functions included, given the value of x (via a number or expression).
Find the relationship between lines, gradients, vectors and equations by drawing a graph with your finger while this app does the rest.
No input of values is necessary. This is an automatic graph app.
Math Graph app – you draw graph, it works out the equation for you.
Trace the graph with your finger. When done, sit back and
study your graph.
The app will draw the line and calculate gradient.
It will also write down the graph equation at bottom left of screen.
On vectors screen, you draw vectors with your finger, and this app analyzes them for you. It is an easy way to learn about simple vectors including addition of vectors.
This native math app is meant for beginners in graphical methods, the first 2 years of learning graphs.
If you have studied complex graphical methods but would still like to remind yourself about the basics, this app will do just that.
You can work with the equations produced at your leisure, re-arranging them to discover more about graphical maths.

See that Android phone in your hand? That's not Intel inside - it's powered by an ARM processor. The 'A' in 'ARM' stood for Acorn, a visionary British company that produced the seminal BBC Micro, and thirty years later - coming full circle - your phone hosts its venerable ancestor today.
Have fun reliving classic games from the 1980s, hosted by BBC Micro preservation website stairwaytohell.com - any questions, please email firstname.lastname@example.org
Works at the full 50 frames per second on most recent powerful Android phones and tablets. This means anything significantly better than an HTC Desire or Nexus One (except, annoyingly, the brand new Galaxy Nexus, because it has the archaic GPU from 2010's Galaxy S pushing 240% of the pixels), or any Android 3.x or 4.x tablet. If you try to run this thing on something like a Wildfire or a ZTE Blade, please don't whinge to us that it runs like a dog - just go and buy a Galaxy S II already ;) It's an extremely faithful emulation, way moreso than other machines' emulators, but if you think you can make it quicker, get involved - it's open-source - code it!
Works with the specialised controls of the Sony Ericsson Xperia Play (but doesn't run at 50 frames per second).

We are also able to offer an in-app payment solution for your programs in such circumstances - please contact us for details.
The rights to the BBC Micro ROMs are believed by the emulator community to have effectively fallen into the public domain, having lain unclaimed for many years - Acorn itself is of course long bankrupt, and the documentation for the rights is rumoured to have gone down in the World Trade Center on 9/11. If you believe that you have a claim to the ROMs that has never been disclosed to the emulator community, or indeed has never been proven under law, remember that this is a labour of love, a free and open source preservation effort, and so please talk to us in the first instance, cheers!
One or two reviewers have commented that it isn't that difficult to write a Space Invaders game for modern mobile devices, but I think they miss the point! This app isn't primarily a Space Invaders game, it's an emulator for the Intel 8080 running on top of the Android OS. It just so happens the emulator loads and executes the original Space Invaders object code, but it could execute other 8080 code. For instance, I don't see any reason why the emulator could not be used as the basis of running the venerable CP/M Operating System on an Android (MS-DOS would require an 8086 emulator).
This emulator was originally developed by Thibault Imbert (http://www.bytearray.org/?p=622). This code ran perfectly on my PC but was EXTREMELY slow on my Samsung Galaxy Tab. All I've done is a bit of "tweaking", and added a few buttons - all credit to Thibault!
As already mentioned this app is NOT for you if you are looking for an ultra fast implementation of Space Invaders, possibly with lots of 'improved' features. That is not its intention. Don't forget this app is primarily an emulator for the Intel 8080 CPU. Here it just so happens to be running the original Space Invaders object code.
A note about colour: The original game ran in monochrome, all the objects were white on a black background. The illusion of colour (the green protective bunkers) was obtained using green cellophane strips!
I apologise, but I am not in a position to supply you all with green cellophane strips to stick on your Android screens to change the colour of the protective bunkers! I will see if this effect can be implemented at screen copy time without slowing things down too much!
This app is free and does not send you a single ad! It doesn't store your IP address or any other information about you whatsoever!
PS: don't leave this app running in the background. Stop it, or it will deplete your battery really quickly! I will fix this in an update.
Now compatible with Android 1.6! (Android 2.0+ required for multi-touch support)
