Original Author of XTiger

  Tiger is a TI-92 emulator for Linux/x86.  It was originally written by
  Jonas Minnberg and was closed source.  There were two versions: the SVGA
  version and an Xlib version.  Jonas Minnberg has not worked on XTiger
  for quite a while and he gave Misha Nasledov the code and permission 
  to GPL it.

4. LOADING TI-92 APPLICATION FILES
   ------------

  You can save any TI 92 files (with .92* file extension) on your 
  SD memory. 

  It may happen that the file is not properly loaded, and so you have 
  to try again.

  To manage applications already loaded in your TI-92, you can use 
  the VLINK menu.

  You can find many applications on http://www.ticalc.org/ and on the 
  official TI ftp site ftp://ftp.ti.com/pub/graph-ti/calc-apps/92/


5. LOADING KEY MAPPING FILES
   ------------

  If you want to modify the default keyboard mapping between GP2X Keys and 
  TI-92 keys you can write your own mapping file. Using notepad for
  example you can edit a file with the .kbd extension and put it in the kbd 
  directory.

  For the exact syntax of those mapping files, have a look on sample files 
  already presents in the kbd directory (default.kbd etc ...). (or use
  the save keyboard file menu to generate a default.kbd file).

  After writting such keyboard mapping file, you can load them using the 
  keyboard menu inside the emulator.

  You can now use the Keyboard menu and edit, load and save your
  default keyboard mapping file inside the emulator. 


6. ROMS
   ------------

  In the directory Pedrom you can find a file ti92.rom. This a ROM 
  distributed under GNU licence. It is part of the tiemu emulator 
  package.

  It is given with GP2X-TI92 for demonstration purposes only, and
  FUNCTIONALITIES CAN'T BE COMPARED TO TI ONES !

  The rom TI-92+ v1.1 can be found on this site http://ti83khdv.online.fr/
  but you have to own the original TI-92 calculator to have the legal right 
  to use it ! 


7. COMPILATION
   ------------

  It has been developped under Linux using gcc with GP2XSDK. 
  To rebuild the homebrew run the Makefile in the src archive.
