API to interface with SEGA file types used in arcade games.

Get / Download:

What can the application be used for?

  • Edit sysfile.dat (insert credits, set free play, reset e-money auth)
  • Synchronize multiple sysfiles (to have same credits/bookkeeping data in multiple games)
  • View and verify ICF files
  • Create ICF files
  • Commit pending updates in ICF files
  • Create DLI files
  • View BootID information in fscrypt containers
  • Verify fscrypt containers
  • Extract fscrypt containers, .app files, .opt files of both standard and APM variant, as well as differential files

What can the library be used for?

  • Write and read the following file types:
    • ICF files (ICF1)
    • sysfile.dat
    • dliApp.ini, dliOpt.ini
  • Extract the following container formats:
    • *.app
    • *.opt
    • *.vhd (with partitions or raw)

Implementation Notes:

  • As this is a highly experimental API right now, consumer applications should check Haruka.Arcade.SegaAMFileLib.VersionInfo.LIB_API_VERSION. This number will be incremented on any breaking changes for consumers.

A note on differential sysfile sync:

Following scenario: You have a master sysfile that you want to gain bookkeeping increases and credits from other sysfiles. Given that the master file is located at C:\master\amfs\sysfile.dat and the sub file at C:\game\amfs\sysfile.dat, run the game as following:

copy C:\game\amfs\sysfile.dat C:\game\amfs\sysfile_diff.dat
SegaAMFileCmd sysfile-sync -f 2 C:\master\amfs\sysfile.dat C:\game\amfs\sysfile.dat File1 NoChange
start /wait game.exe
SegaAMFileCmd sysfile-sync -f 1 -d C:\game\amfs\sysfile_diff.dat C:\master\amfs\sysfile.dat C:\game\amfs\sysfile.dat File2 DifferentialToFile2

So for example, in the master application 5 credits were inserted and bookkeeping registered 32 service presses, during this game session I press service once and spend two credits, then the master application will display 3 credits and 33 service presses. The bookeeping count of service presses in the game also has gone up by 1. (regardless of what the count is)
