Ok, you will find the C program attached. It is in french, but very 
simple to use : ./split_bank <name_of_the_file.hex> and it generates 
files named partie_1.hex, partie_2.hex, ...

I use gcc to compile it (Linux or cygwin on windows), but it should work 
with any C compiler. Licence of the program is GPL. If you can't compile 
it, I will send you the exe file + required dll, but off-list.

I also send you the macro for javakit. Be sure to use -macro option for 
javakit. Note that you can also load files manualy, this is just longuer.
