TI-99/4A Emulators

Classic99 - Windows

Author: M. Brent (AKA Tursi)

Classic99 was formerly the 'Ami99 Emulator'.
It is currently in version 3.1a2, and has been updated to include new ROMs, 'magic' disk ability has been added so things like Editor/Assembler can have their support files available, a menu for ROM/system selection has been added, and it now had more reasonable defaults for today's machines.

TI994W - Windows

Author: Frederik G. Kaal

Still a work in progress, but most functions work. See the 'readme' file for more information.

You can use the same ROM and GROM image files as for V9T9 or MESS (I had to rename the MESS file '994agrom.bin' to '994agrom.gpl' in order for it to work).

    Shareware emulator which is no longer supported by its author, Edward Swartz.

    On some computers, V9T9 does not detect the processor if it is a 386 or higher. To remedy this, Kerry Lee High Jr. has removed the processor check from v9t9.exe. If you've been having problems, download v9t9fix.zip, unzip it, and replace v9t9.exe with v9t9fix.exe.

    MacV9T9 (For the Macintosh)

    I don't own a Mac, so I have no personal experience with this emulator but it apparently uses the same file types (Disk and ROM) as the PC version of v9t9. The author states that this version is incomplete and he is not certain when he will make a final release.
