I&#x27;m genuinely curious about this, since I wasn&#x27;t around in those days.<p>For a game being implemented (and probably having design changes on the fly as problems crop up since there was no time for a design phase) in assembly, with instruction- and register-level hacks to save the 128 bytes of memory, with no source control aside from sneaker net, how many developers can reasonably work on it at the same time? 1? 2? I mean at that level don&#x27;t you need to hold the whole code and memory map in your head? Each change can have huge repercussions.
