What you see on a PC:

What you see on a mobile phone:

• Check ScratchPad first byte, which is <number of files downloaded>
• Check ScratchPad offset 2-5 (second byte to fourth byte, integer), which is <bytes required to download>
• If <bytes required to download> = 0, 
  - Download init.bin, store in offset 2-5, 
  - Update <number of files downloaded> = (<bytes required to download> + 102399)/102400
• If (<number of files downloaded>*102400) < (<bytes required to download>)
  - Fetch <number of files downloaded>.bin from the base (web) address of the i-appli.
  - Store the data in offset 8192 + <number of files downloaded>*102400
  - Loop this IF condition.

* 102400 bytes is the maximum size of a .bin file
* Storage facility are all provided by ScratchPad
* Network communications are in HTTP 

Web Server Folder Contents
The web server base path of the i-appli contains the following files:

• RPGa.jam
  i-appli descriptor, simmilar to .jad for MIDP
• RPGa.jar
  Main RPG Tsukuru for Mobile i-appli, remains constant for every game
• init.bin
  Contains the total size of the .bin files (excluding this).
• <n>.bin
  Where <n> is a real positive integer ranging from 0 - ((<bytes required to download> + 102399)/102400 - 1)
