I think noucermane is correct. Your point that there wasn't any software DRM does not mean that they did not intend it as DRM. I expect that they did a cost benefit analysis of additional electronics for SW DRM vs revenue lost due to hackers like this one for this version of their product, and found the tradeoff acceptable. This does not mean that if this hack became easily available and widely used, that they would not implement SW DRM on a later revision. Who knows, maybe the current version is already ready for SW DRM, it's just that they haven't felt the need to release the DRM version of the cartridge yet.
