================================ READ HERE ================================ Programmed by: Nuvalo Based on the code "JavaBoy" programmed by Neil. The authors do not take responsibility badly in some way of the operation of the program IMPORTANT : The emulator is still very slow, thus is very probable that take too much time in showing an image of the ROM that has been loaded. If when executing it does not give it problems but it does not leave any image, it is probable that it is by the slow thing that is. In order to know if it has failed, to select the button of "options", and if continuous without giving error it is even necessary to hope a good short while. In order to know if it works it provides to a noncommercial ROM that does not take much in loading (5-10 minutes) and which it shows as the emulator works. It is already put in the file "MJavaboy.jar".you only need to execute the application. ================================ READ HERE ================================ Indice ****** 0. Introduction

To FAQ on MJavaBoy
**************************************************************************
Why remains in target the screen, in spite of taking a good short while working?
In slow mobiles it is probable that late between 3 and 4 hours in showing an image.

Why it is so slow?
The memory that uses is so great that there is to paginar it (to divide it in pieces) and to keep it in
archives aside. The load and unloads of these archives causes that he is very slow.
Also by the fact to be programmed in java it reduces speed to him.

Leaves an error < put error > to me, what means?
send me the errors to [e-mail]
