I removed the SHUTDOWN MM entry from the .pbt and it boots uLaunchelf 4.12 just fine from flash, the MC and a USB Thumb drive. see note below
I have CC 2.0 SLE with R34 firmware in a V9 NTSC console.
Heres the .PBT im using for ULE:
Code:
#
# Application Manager Script for BootManager 2
#
# Change this information to describe the application.
SET "TITLE" "ULaunchELF"
SET "VERSION" "v 4.12"
SET "AUTHOR" "EP, Dlanor"
SET "DESC" "An explorer like application able to manage files and load elf files"
SET "MEDIAS" ""
#
GOTO "$ARG1$"
:LABEL_NAME
ADDWIDGET "LABEL" "$ARG2$$TITLE$ v$VERSION$"
EXIT 0
:QUERY
ADDWIDGET "CALL" "$TITLE$" "$BM.TXT_VERSION$: $VERSION$ $BM.TXT_AUTHOR$: $AUTHOR$ $BM.TXT_DESC$: $DESC$" $ARG2$ "$ARG0$" "$ARG3$" "$ARG4$" "$ARG5$"
EXIT "0"
:INSTALL
IF FAIL COPY "$PWD$" "$ARG2$:/BM/APPS/ULE"
MESSAGE "Failed installing $TITLE$!"
RRM "$ARG2$:/BM/APPS/ULE"
RETURN -1
ENDIF
EXIT 0
:REMOVE
IF FAIL RRM "$PWD$"
MESSAGE "Failed removing $TITLE$!"
RETURN -1
ENDIF
EXIT 0
:RUN
LOADEXEC "PBAT" "$BM.SCRIPTS$/LOADEXEC.PBT" "$PWD$/ULE.ELF"
EXIT "0"
*NOTE*
But it may crash, due to some incompatability with BM. Heres an explaination from Jones23:
