Newbee - black screen

[Katagia]

Hi

I have just modded my PS2 with CC 1.1, fm1.9 and BM1.8
I've got some apps working with the bootmanager: SMS and
execftps.

Next I wanted to install uLaunchELF 3.78.
I tried to install it the way I've installed SMS 1.7rev4.
I have put the ELF file in /BOOT/APPS/ULAUNCH/ULAUNCH.ELF
and modified APPINFO.PBT:
################################################## #####################
# ULAUNCH v1.2 #
################################################## #####################

SET "CMD" "$ARG1$"
SET "SRC_PATH" "$ARG2$/ULAUNCH"
SET "DST_PATH" "$ARG3$/ULAUNCH"

GOTO "$CMD$"
RETURN "-1"

:QUERY
# Change this information to describe the application.
SET "APP_TITLE" "ULAUNCH"
SET "APP_VERSION" "v 0.69"
SET "APP_AUTHOR" "SlicStik"
SET "APP_DESC" "ULAUNCH allows you to explore, add and remove files from your memory cards and Hard Drive."
SET "APP_MEDIAS" ""
RETURN "0"

:RUN
RUNAPP "$SRC_PATH$/ULAUNCH.ELF"
RETURN "0"


I tried both ELF files: compressed and uncompressed. They won't start and
I only see a black screen. This happens with many applications too.
I read there are different Versions of a so called MegaPack. Thex differ in
the required BM version.
Is the only difference the new config file schema or are the applications
different?

Cheers,

It has to look like this:
:RUN
SHUTDOWN "MM"
RUNAPP

Use the SHUTDOWN "MM" with all the ELFs that are not working.
And it should solve your probs with SMS too.

EDIT:
I've attached an complete APPINFO.PBT for ULE as an example for you. And don't listen to anarchy2007. He's still using BM1.4, because he doesn't know how to make an APPINFO.PBT.

Great, thank you Jones23. The problems are gone!
Creating the APPINFO.PBT looks very similar to batch
programming.

Can you tell me what the command "SHUTDOWN MM" do?
I found some hints about this command but no description.

Cheers, Katagia

Glad to hear that.
Yes it is, and it's really not that difficult to create them.

The SHUTDOWN "MM" disables the BM's ModuleManager. It's similar to booting in minimal mode, meaning that all screen-fixes(PAL/NTSC, X/Y settings), etc are disabled.

The BM uses PS2-RAM and IOP to activate those fixes, which can cause conflicts with some progs(ULE) and games(SIMS2). And some games(GTASA) are not running smooth anymore(esp videos) with activated PAL/NTSC-fix, because the RAM used for the fix can't be used for the game anymore.
So it's best to turn them off.
