This should result is a much more accurate sound for synthesized speech. First, the speech emulator code has been updated to use the proper lookup table values. Version 0.15.0: This is mostly a maintenance release with small improvemnts to several areas. If you want to run the QI console, you can now type: `ti99sim-sdl -console=ti-994a-qi.ctg`

A command line option to use a specific console ROM file.

All disk images should now be readable & writeable. Note: The disk contents are not stored in the save image, so if a disk has been modified since the save was created, re-loading the save image may result in unexpected behavior if a disk operation was in progress when the image was craeted. Loading a save image will now swap cartridges and any loaded disks to recreate the setup used to create the image.

A reworked save image format (any old save images will not be usable).

Added support for numeric keypress events from joystick buttons. Most of the smaller changes are code cleanup and tweaking implementation issues, bug fixes in disk image code, updated helper scripts, and fixing several potential crashes. Version 0.16.0: This release includes a lot of small changes from the past few years as well as a few bigger ones. If you have a working copy of v9t9, instructions are included to help you create the required cartridge. Please don't e-mail me asking for a copy - I won't even bother to respond. Texas Instruments will not allow these to be distributed, so you'll need to find a way to get them yourself. Note: In order to run the emulator, you need to create a cartridge that contains the console ROM & GROMs from the TI. In the spirit of Linux and Open Source, I'm releasing the code under the GPL license. Now I've decided to try my hand at a Linux/cross-platform version. When I got bored with that, I ported it to Windows and added sound support.

Then I added graphical support for the OS/2 Presentation Manager. At first is was a simple text-based simulation of the TI. Instead of doing the smart thing (looking for an existing emulator), I sat down and wrote my own. A few years back, I thought it would be neat to be able to play my old TI games on my PC. Well, here's my contribution to the TI-99/4A community.
