My self-created Nyx Custom Icon doesnt work

[MSco]

I have created an nyx custom icon by combining two other icons I found in this forum. I have created this one: attached as icon_sysmmc_cfw.bmp

However, it shows just an empty icon: attached as switch_screen.jpg
The icon on the right should be a combination of the two icons on the left.

I created this icon with gimp as RGBA, it has 192x192 px and has the same file size as the working icons (144,1 KiB).
Any ideas, what I did wrong? Or how can I create this Icon correctly?

And the content of your hekate_ip.ini?

This is my hekate_ipl.ini

[config]
autoboot=0
autoboot_list=0
bootwait=0
autohosoff=0
autonogc=1
updater2p=1
backlight=100

[Stock - sysMMC]
fss0=atmosphere/package3
emummc_force_disable=1
stock=1
icon=bootloader/res/eckig/icon_stock.bmp

[CFW - emuMMC]
fss0=atmosphere/package3
kip1patch=nosigchk
emummcforce=1
atmosphere=1
icon=bootloader/res/eckig/icon_atmosphere_hekate.bmp

[CFW - sysMMC]
fss0=atmosphere/package3
kip1=atmosphere/kips/*
emummc_force_disable=1
icon=bootloader/res/eckig/icon_sysmmc_cfw.bmp

However, I am not sure, if really saved is as rgba. How can I do this with gimp? I exported it like in the screenshot attached here. Was it correct or should I use another option?

Where on the SD card is stored the file?

Ok, I have found the issue. It is working now.

I had to add an alpha channel in gimp before exporting, after that I could correctly export it as ARGB. Now, it shows correctly.

Thanks for your help!

P.S: The image is stored in sd:/bootloader/res/eckig/icon_sysmmc_cfw.bmp
