INTRODUCTION
------------

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.

PSP-XTI is port on PSP of the latest Xtiger
version.

Thanks to Danzel and Jeff Chen for their virtual
keyboard, and to all PSP-SDK developpers.

The IR keyboard support is based on the work of 
Harald Fielker (author of the PSP IR Keyboard 
Library).

This package is under GPL Copyright, read COPYING
file for more information about it.

STANDARD CONTROL
------------

In the TI92 emulator window, there are three
different mapping (standard, left trigger, and right
Trigger mappings).  You can toggle between while
playing inside the emulator using the two trigger
keys.

4 letters of the highlighted square.

IR KEYBOARD CONTROL
------------

You can use an IR-keyboard with PSP XTI. 
Personally i use a Targus Universal Wireless 
keyboard, which is one of the best.

You can edit the file pspirkeyb.ini and modify it
according to your IR keyboard model :

# 1  - Compaq/HP foldable keyboard
# 2  - Snap'n'Type
# 5  - HP Slim keyboard
# 8  - Belkin IR (not IrDA)
# 9  - Flexis FX-100 keyboard
# 10 - Benq G250 gamepad
# 12 - Micro Innovations Foldaway keyboard
# 13 - Micro Innovations Datapad
# 14 - Compaq MicroKeyboard
# 15 - Targus Universal Wireless keyboard
# 18 - Freedom keyboard
# 19 - NOVAETS - KIS2 - IR Keyboard
# 20 - Palm Universal Wireless Keyboard
# 21 - Hama Palm IR keyboard

You can use the arrows of your keyboard to navigate
through the menus. The ENTER key is use to validate,
and the Escape key to cancel.

Inside the TI-92 window, you can press TAB to return
to the emulator menu. 

The key CTRL-A -> CTRL-G are mapped to F1 -> F7.


LOADING TI-92 APPLICATION FILES
------------

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

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/


LOADING KEY MAPPING FILES
------------

If you want to modify the default keyboard mapping
between PSP 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. 


   Enjoy,
