Virtual TI v2.5 beta 5

Virtual TI v2.5 beta 5

Written by Rusty Wagner

Requirements

* A Pentium or better running Windows 95 or higher,

Windows NT 4.0, or Windows 2000

This emulator will run ROMs from the TI-82, TI-83,

TI-83 Plus, TI-85, TI-86, TI-89, TI-92, TI-92 II,

and/or TI-92 Plus calculators.

A menu containing the functions of the emulator can

be obtained by right clicking on the LCD.

Features:

* ROM versions are automatically detected

* Switch between ROM versions without restarting the

emulator

* Built-in ROM dumper with automatic error correction

* Archive memory support for TI-89 and TI-92 Plus

* Send files to the calculator

* Receive files from the virtual calculator

* Use a TI Graph-link cable or serial cable to connect to a real calculator

* Connect two instances of the emulator with a virtual

link

* Sound emulation

* Save and load the state of the calculator. Any

changes to the Flash ROM (i.e. archived variables)

will be included in the state.

* 4-level and 7-level grayscale support

* Full skinning system with editor

* Resize emulation window to any size

* Screenshot feature which saves to a BMP or to the

clipboard

* Option to emulate at either the true speed of the

calculator or the fastest the computer can handle.

* The letter keys are aliased to produce their

respective letters. No need to press the Alpha

key, just type.

* A full-featured graphical debugger

* Code disassembly pane. ROM call addresses are

replaced by the name of the ROM function. DB92

symbol information is also used when available.

* Code breakpoints. Does not modify memory, so

they are completely transparent.

* Data breakpoints can be set on a single byte,

word, or dword, or a range of addresses.

* Set a breakpoint on entry to an assembly program

automatically.

* View and change the value of the registers

* Hexadecimal memory view/edit pane with search

capability

* On the 89/92(+), a handle pane which lists all

allocated handles. Allows user to jump directly

to the start of the handle within either the

disassembly pane or the memory pane.

* On the 82-86, a variable pane which lists all

variables and their types. Allows user to jump

directly to the start of the variable within

either the dissassembly pane or the memory pane.

* Real time updates to the LCD, even with grayscale

* Log reads/writes to memory or changes to

individual bits

Limitations of this beta 5 version:

* 8-level grayscale on the TI-86 doesn't work properly

yet

* Key redefinition is not yet implemented, although the

program should now work on international keyboards

without it

* Receiving of backups from the virtual calculator is

not implemented

* Log link port send/receive is not implemented

* TI-82 ROM dumper does not work

* TI-83 Plus does not yet have Flash support

This emulator requires a ROM image from a real

calculator that you own. I will not send you any ROMs.

You can use the built-in ROM dumper to obtain an image

from your calculator.

If you already have a ROM dump, place it in the same

directory as VTI.EXE (this is done automatically if you

use the built-in dumper). Make sure it has the

extension .rom, .bin, or .dmp. The file name may be

anything (the calculator and version number are

automatically detected). Any .tib Flash ROM upgrades

will also be recognized if placed in the same directory

as VTI.EXE. The latest version will be used by default,

but you may revert to an earlier version from the

emulation mode dialog.

To send a file to the calculator, press F10 or drag and

drop from explorer.

To enter the debugger, press F11.

To bring up the emulation ROM version screen, press F12.

The debugger is for the most part the same as any other

graphical debugger. One thing to note is the color of

the lines in the disassembly pane. Red means

breakpoint, green means current PC, and blue means

currently selected. If a line is in more than one

state at the same time, the colors will be combined.

For example, a breakpoint that is selected will combine

red
