       | This is exceedingly cool use of cartridges. Just as a thought
       | experiment I've often wondered if some of the cartridge based
       | consoles could be expanded considerably. Along the lines of this
       | project, would it be possible to throw an arm chip in a cart and
       | send these as h.264? I'm not at a computer but would love to see
       | how differently some modern codecs compress.

         | Yes. The Harmony Cart and the UnoCart/PlusCart both have ARM
         | chips. Games have been made that make full use of the chip.
         | Probably the most impressive IMO being Robotron from
         | ChampGames.
         | 
         | The PlusCart also includes a WiFi chip for Internet access.

         | On top of all the other examples, Hayazashi Nidan Morita Shogi
         | 2 was a cancelled SNES games from 1995 that was going to us a
         | 21MHz ARMv3 processor for AI. I just like the idea that they
         | would throw in a processor that was probably about 5-10 times
         | the power of the main system CPU.
         | 
         | That a very similar spec ARM processor would become the brain
         | of the Gameboy advance many years later.

       | on the back, including Star Wars and Kramer vs. Kramer. I'm
       | curious why he chose "Model CX2615" for this though. That was
       | "Demons to Diamonds" and was released in 1982, though his manual

         | The 2600 is streaming the data from the cartridge, including
         | the program that is run on the 2600. We should remember that
         | there's no frame buffer in the 2600, so there's considerable
         | work done by the 2600 every frame - just as there is when its
         | working with any other cartridge.
         | 
         | The 2600 kernel that runs on the 2600 is excellent but the
         | encoding method is what makes a real difference here. Lodefmode
         | did a great job with this. The use of playfield/background and
         | player colour is exceedingly clever.

           | No frame buffer. The target CRT display scanned an electron
           | beam from left to right in about 63 microseconds, snapped it
           | back in just a couple more microseconds, working gradually
           | downward to produce about 200 such lines before taking a
           | couple milliseconds to return to the top. The 6507 had to
           | literally write the pixels into that raster in real time, and
           | was just skin of the teeth able to do that, hence the phrase
           | 'racing the beam', leaving just the retrace times for any
           | other program code to run. To get video from a cart, all that
           | still has to happen. Pretty cool.
