Well, depends what you mean by 'require'. If it's the width of the data bus, anything will run. If it's the width of the address bus, it will only fail if your Amiga has less memory than the software's minimum requirement (such as if you have an A500 and can only have 12MB)
Any other errors caused by narrower buses are bugs or contious exploitation of CPU model quirks to make a demo or such show an effect a few cycles faster
Maybe you mean in the broader sense, 'software written for high end Amigas only'?
