# TilEm on MacOS

These instructions are for TilEm 2.00. Here's my TilEm 0.973 page. I last built this in March 2016 on my El Capitan system, YMMV.

TilEm is a Linux emulator for certain TI graphing calculators including the TI-83 and TI-84 series. This is more or less how I got TilEm running on my MacOS system. I'm no expert; suggestions welcome.

I basically followed these instructions, modified slightly for MacPorts.

1. Install MacPorts.
2. Using MacPorts, install gtk2 and libticalcs2
sudo port install gtk2 libticalcs2

4. Unzip and build it:
tar xvf tilem-2.0.tar.bz2
cd tilem-2.0
./configure
make
sudo make install

5. TilEm really just emulates the calculator hardware; it depends on an actual TI calculator ROM to act like a calculator. Here's one way to get one:
2. Download and install wine. MacPorts has a wine port but at this writing (now years old) it does not work with Snow Leopard so instead I used this handbuilt and hand-tweaked version.
This is how you would install under MacPorts:
sudo port install wine

3. Using wine, open the downloaded SDK (named 83psdk_setup.exe). This should open the Windows installer; when it asks where to install, make sure it goes to a Mac directory, not a native Windows directory. (Of course, instead of using wine, you could also install the SDK on a Windows VM (e.g. Parallels, VMWare, VirtualBox) or an actual Windows machine and just copy the ROMs over to the Mac.)
4. Copy the .clc files to wherever you want them:
cp sdkdir/Exe/*.clc wherever

6. Start X-Windows
7. Start tilem2:
tilem2

(You may have to turn the calculator on before it works!)
