On 17 December 2012 the Raspberry Pi Foundation, in collaboration with IndieCity and Velocix, opened the "Pi Store", as a "one-stop shop for all your Raspberry Pi (software) needs". Using an application included in [[Raspbian]], users can browse through several categories and download what they want. Software can also be uploaded for moderation and release.<ref>{{cite web|url=http://www.raspberrypi.org/archives/2768

The default split was 192 MB (CPU RAM), which should be sufficient for standalone 1080p video decoding, or for simple 3D, but probably not for both together. 224 MB was for Linux only, with just a 1080p [[framebuffer]], and was likely to fail for any video or 3D. 128 MB was for heavy 3D, possibly also with video decoding (e.g. XBMC).<ref>[http://www.raspberrypi.org/forum/general-discussion/config-txt/page-3 Raspberry Pi boot configuration text file]</ref> Comparatively the Nokia 701 uses 128 MB for the Broadcom VideoCore IV.<ref>{{cite web|url=http://www.raspberrypi.org/forum/general-discussion/nokia-701-has-a-similar-broadcom-gpu |title=Nokia 701 has a similar Broadcom GPU |publisher=Raspberrypi.org |date=2012-02-02 |accessdate=2012-06-22}}</ref> For the new model B with 512MB RAM initially there were new standard memory split files released( arm256_start.elf, arm384_start.elf, arm496_start.elf) for 256MB, 384MB and 496MB CPU RAM (and 256MB, 128MB and 16MB video RAM). But a week or so later the RPF released a new version of start.elf that could read a new entry in config.txt (gpu_mem=xx) and could dynamically assign an amount of RAM (from 16 to 256MB in 8MB steps) to the GPU, so the older method of memory splits became obsolete, and a single start.elf worked the same for 256 and 512 MB Pis.<ref>[http://www.raspberrypi.org/archives/2296 introducing new firmware for the 512MB Pi]</ref>
