In the Basic environment, the ROM is located at #38. As long as you don't
use it you can easily switch it away (although you will need an extra
mapperpage for it I don't really think that is a problem), but when you _do_
use ROM routines, you will have to disable interrupts and switch back ROM
everytime you call a routine. And what will happen when one of the
ROM-routines enables the interrupts??? It will call the 'old'
interrupt-routine, which can be highly undesirable, for example when running
a JoyNet-program, in that case the normal interrupt will disable two of the
three transmission 'channels'.
