# 2. TiEmu images

Some vocabulary...
To run this emulator you will need an 'TiEmu v2' image. An image is converted from :
- a ROM dump,
- a FLASH upgrade (not applicable to TI92).
As ROM dumps are copyrighted by Texas Instruments Inc, they will never be distributed with the emulator. To get a ROM dump, you can use TiLP or any other ROM dumping program.
If you can't get a ROM image (because you don't own the calculator or you want to test the emulator), you can download a FLASH upgrade from the TI web site (http://education.ti.com) or use PedroM (GPL'ed replacement OS shipped with TiEmu).
Please note that images converted from a FLASH upgrade (fake image) have neither a boot block nor a certificate. They are not as complete as ROM dumps.
[If you already have a ROM dump or an upgrade, place it in the 'images' directory. Make sure it has the right extension (.rom or .89u). It will be automatically converted and deleted.]
A TiEmu image is made up of an header and the ROM dump or FLASH upgrade. The format is documented in the doc folder of the source archive.
Please note that ROM contents is copyrighted by Texas Instruments. You are not allowed to copy and/or distribute any ROM image!
For more informations, see the License Agreement provided with any FLASH OS upgrade.
