If you don't have this file, you can use mkspch to create one that will keep the emulator happy. You should also place a copy of spchrom.bin into this directory to enable speech synthesis. Once you have created the console ROM cartridge, copy it to either ~/.ti99sim/console or /opt/ti99sim/console. Without it, the emulator will not do anything useful. This ROM cartridge contains the operating system, the BASIC interpreter, and a description of the RAM configuration for the computer. Once you have run make install, you will need to create the console ROM cartridge TI-994A.ctg (see convert-ctg below for instructions) in order to run the emulator.

This section describes how to create and install your console ROM files by hand if you prefer to do it yourself. NOTE: Since v0.14.0, the setup script found in the scripts folder is provided to help create a set of both console & cartridge files to get you started. If there is no logical directory for a given file, only the base directory will be searched. When looking for a file, the appropriate sub-directory for that file type will be searched. When searching directories other than the current directory, the following sub-directories are considered: Under Windows, the search is limited to the current directory followed by the directory specified in the environment variable HOME (if it is defined at all). When loading files (ROMs, cartridges, disk images, …), ti99sim will look in the current directory, ~/.ti99sim, and finally, /opt/ti99sim. In addition to installing the binaries, symbolic links to them will be created in /usr/local/bin (which should already be in your path). The default directory is /opt/ti99sim and the binaries will be installed in /opt/ti99sim/bin. This will create the default directories and install the binaries. Make sure you have sufficient privileges to create/write to the installation directories and type: In order to get a working installation, you should run the included setup script which will create the required files.

Texas Instruments will not allow these to be distributed, so they are not included with ti99sim. NOTE: In order to run the emulator, you need to create a cartridge that contains the console ROM & GROMs from the TI-99/4A. If you're interested in writing documentation, let me know.

Now it's been ported to Linux and Mac OS X and more features are still being added.ĭISCLAIMER: I'm not one for writing a lot of documentation, so you're encouraged to look at the code to see how some things work if they're not described here.

Later, it was ported to Windows and had sound support added. Then it was ported to OS/2 and graphics support for the OS/2 Presentation Manager was added. At first it was a simple text-based simulation of the TI (ti99sim-console) running under MS-DOS™. This is the latest incarnation of an emulator for the TI-99/4A that I've been working on, on and off, since 1993.
