What is "SAS"

Otherwise known as Save Application System, SAS apps/folders are single directory folders that play nice with the memory card filesystem as subdirectories can easily break it.

SAS Applications include:

Memory Card icons for visual indicator as to apps purpose and critical status to your boot environment.

title.cfg plain text file for other apps such as OSDMenu, OPL, OSD-XMB and PSBBN DEP to list apps to run without user intervention.

title.cfg example

    title=[APP] NHDDL                   # used by newer OPL and first "page" of info
    Title=NHDDL                         # used by older OPL and second "page" of info
    boot=nhddl.elf                      # relative path to ELF

    Version=1.2.0                       # version of app
    Release=November 13th, 2025         # date app was updated
    Developer=pcm720                    # who wrote the app
    Genre=Homebrew                      # category of "game", in this case homebrew
    Description=A Neutrino launcher     # description of app. If too long OPL will crash
    Source=github.com/pcm720/nhddl      # where to find more info regarding app
    Notes=SAS Compliant                 # Of course its SAS compliant!

    CfgVersion=8                        # Info for OPL
    $ConfigSource=1                     # Info for OPL

Folder prefix (if app supported) such as APP_OPL (Application) or DST_ROMVERCHK (Diagnostic Service Tool) for organization. Example full path: mc0:/APP_OPL/OPL.ELF
- APP_ Application
- SYS_ System (caution when deleting)
- DST_ Diagnostic service tool
- DBG_ Debug
- RTE_ Run time environment (App that relies on other scripts usually like Athena or Enceladus.)
- EMU_ Emulator
- PS1_ Playstation 1
- GME_ Game
Packaged via a container called a psu. This is used to transfer game saves, but adopted for SAS so that all assets are contained. Even date/time is preserved so that Apps are always in order alphabetically by type in the MC Browser!

wLE ISR eXFAT
