Internal Memory

  AndyF

   Probably a silly question to ask, but does anyone know of the internal
   memory storage of the mini?

   I'm just wondering how much scope there could be in the future for the
   addition of more games... and yes, I know that each game is only around a
   few dozen Kb in size, but internally, there would only be a finite amount
   spare (unless the capability of adding extra flash via USB is considered a
   possibility)

   I don't know if the picture in the following link can be considered as
   reliable. In any case, the Flash NAND chip should be of 256 Mbytes (2
   Gbit).

   Yeah would be cool to just add games to the system without having to have
   a usb stick in

   PS: the Toshiba "TC58NVG1S3HTA00" should be a NAND E2PROM of 2 Gb (256
   Mbytes)

   it's more memory than I thought, so I wonder how much is actually unused
   at present

   (given that there would be overheads such as HDMI etc)

   Well, put it like this, the entire firmware file for 1.0.6 is 2.5MB.
   That's likely to be compressed, however I imagine it includes all 64 games
   and the carousel app. The save states are probably a full memory dump, so
   64K each. There are 4x65 of those (including BASIC) which is 16.5MB.

   Make of that what you will...

   [4]RetroBiker That's if the firmware is the full image?

     [5]RetroBiker The save states are probably a full memory dump, so 64K
     each. There are 4x65 of those (including BASIC) which is 16.5MB.

   Each savestate has a related PNG (snapshot), so you need to add about 5-10
   kbytes per savestate... in any case, a good percentage of NAND memory
   should be free! [6];)

   Oh, absolutely. Just a few calculations, however the machine is a very cut
   down Linux and you can do that in very little space when you try (no
   networking, only 2 apps, etc).

   I offer no warranty, expressed or implied. Caveat emptor.

   I don't know for sure, but probably the firmware update doesn't include
   the 64 games images. To make a comparison, the dump of the SNES mini
   kernel is 2.6 Mbytes and it doesn't include the 21 bundled ROMs (the SNES
   mini and theC64 mini interfaces are rather similar).

   [8]Gab75 Its a pity there is not a tool like there is with the snes mini

   [9]Darbyram "certain things" you shouldn't say/write in the official
   forum! [10]:P [11]:P Joking aside, for now there isn't a tool similar to
   the one used to "customize" the NES/SNES mini... in the future who know?
