Util para probar cosas con SIDE2 directo en el PC. Este video me sirvio de guia  para poder crear una imagen de disco VHD con la emulacion SIDE en altirra y luego guardar la imagen en una tarjeta SD usando “HDD Raw Copy Tool“

Added several features to the B2FJ Virtual Machine with minimal impact in the footprint. 

Now we have arraycopy native implementation in C.

The garbage collector pass the tests, but using String generate a lot of things that must be cleaned. For this reason I decided to create a TinyString class that seems more suitable for cases when the space restrictions that we have in an 8-bit environment, can cause problems. All developments looks promising.

With the TinyString class, now we can send strings and numbers to the console whithout was additional memory and with the native array copy the memory footprint and object creation was improved.
