Does your ROM have UC? Did you check the Sashimi manual?:

AUTORUN and UC INITIATED OPTIONS

Although starting SASHIMI in Auto Install mode takes only a few quick seconds, there have been questions on how to further automated SASHIMI following a clean install.
Due to these requests to automate SASHIMI to run without additional manual intervention, the following methods were developed:

AUTORUN - AUTORUN allows SASHIMI to run automatically when a Storage Card containing SASHIMI is placed into a device. This option is best suited for a brand new device or when provisioning many devices (such as in a corporate usage). To use Autorun, simple move/copy the \SASHIMI\Program\2577 directory to the root of the Storage Card. When the Storage Card is next inserted into a device, SASHIMI will automatically execute in Auto Install Phase.

TIP: Autorun.exe can be run manually from \SASHIMI\Program\2577 to do a quick launch in AUTORUN mode following a clean flash!

NOTE 1: Some other applications may also use a \2577 directory in the Storage Card root for AUTORUN functionality (e.g. TomTom). If this is the case then you must remove or rename the other application's \2577 directory to use SASHIMI's \2577 directory. Only one \2577 directory with its corresponding Autorun.exe file can be active on a device at any time.

UC Initiated - UCInitiated functionality is provided by a set of files in the \SASHIMI\Program\UCINIT directory. Simply copy the SDCONFIG.TXT file from this directory to the \SASHIMI\Program\INI directory. When UC runs it will read this SDCONFIG.TXT file and automatically configure SASHIMI to perform an Autorun following UC's reboot.

NOTE 2: You will need to manually edit the provided SDCONFIG.TXT file if you are using something other than "Storage Card"

TIP 1: A registry key will be set to prevent multiple AUTORUNs of SASHIMI in both of the above scenarios. See the SASHIMI REGISTRY ENTRIES for more information. This behavior can be overridden or manually reset using the Advanced Settings.
