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. Known issues are TE2 text-to-speech and minor timing discrepancies.Well, here's my contribution to the TI-99/4A community.

High compatibility - Classic99 runs most software correctly.

Integrated debugger - offers disassembly, memory view, register dump, debug output, and single step.

Support for the 'UberGROM' GROM emulation system.

Support for up to 32MB of bank-switched cartridge.

Certain disk files, such as QUEST for Tunnels of Doom, and the Editor/Assembler files, are also built in.

Built-in ROMs - provided under license from Texas Instruments - includes console ROMs for the 99/4, 99/4A, and v2.2 99/4A, as well as a number of games and user-provided software, right from the menus.

Speed control - the CPU may be over- or under-clocked in configuration, or the entire system may be sped up.

Display available via GDI or DirectX, both Windowed and Full Screen available for DirectX

Display filtering - both to enhance resolution and to reproduce NTSC artifacting, through external DLLs based on code contributed by third parties.

Speech emulation through external DLL, based on publically available 5220 emulation (some modes not working due to timing issues).

Experimental implementation of the TI Disk Controller card for disk images (full read/write but with TICC hardware limits).

Read-only access of disk images today, both PC99 and V9T9 format.

(In practice some TI programs will still limit filename length). Use of Windows paths permits subfolders and variable length filenames, as well as removing the limit on files on a 'disk'. Capable of reading Windows text files as DISPLAY type files to allow direct loading of Windows generated assembly object files.

Disk emulation via the 'Files On A Disk' approach, compatible with V9T9 and TIFILES formatted files (with TIFILES preferred to allow transfer with a real TI).

9938/F18A compatible 80-column text mode supported.

F18A GPU emulation (no graphics modes are supported however).

Nearly full emulation of the 9918A including undocumented and illegal mode settings and pixel-accurate sprite collisions.

Full emulation of the sound system, including the noise channels with variable pitch and simulated DAC via both high frequency and CRU input.

Partial emulation of the 9901, including timers, DSR select, joystick and keyboard.

Emulation of the 9900 including cycle counting and external opcodes.

Sometime after being ported to Windows it was renamed to Classic99 after confusion about whether it was still for the Amiga or not.

It also has some other niceties, such as the use of DirectX for speed-up in drawing, along with the ability to also use a 'filter' to make the output look more like a TV image.Д¬lassic99 started life on the Amiga as Ami99 in '94 or '95, and was later ported to DOS with the same name. It doesn't necessarily require a disk image in order to load and use a file. It is special in the fact that the author not only acquired permission from Texas Instruments to distribute code with their copyrighted ROMs, but also allows his own source code (minus the copyrighted ROMs) for others to use.Д¬lassic99 has an interesting quality in that it can read a raw TI file (as binary) from a folder on a PC. Classic99 is a Win32-based emulator, whose author, Tursi (Mike Brent), is very talented in many other arenas, including those of console gaming.
