Hardcoded Image List of SMBX Engine
Hardcoded images of SMBX Engine - there are image resources embedded into executable file of the game and can't be normally customized.
Customization support per engine
SMBX 1.3 and older
Original SMBX engine doesn't provide any ability to customize hardcoded images. So, to customize them, there are various hack tools required to override current image with a new one. There is a limitation presented that requires to put the image with equal or lesser file size to avoid the leading damage of the executable file.
LunaLua and SMBX2
The LunaLua since version 0.7.3 adds an ability to customize hardcoded graphics. The SMBX2 inherits this ability. Simply save any hardcoded image listed in a table of graphics below on your PC, edit it if you want to, and place it in your SMBX level or episode folder. There - now you will see your custom image in the game without the need to override the executable file of SMBX!
TheXTech
Since foundation of TheXTech, the game is no longer contains a truly harcoded graphics: all previously hardcoded graphics now stored at the "graphics/ui" directory. However, there wasn't made the ability to customize them at episode or at level. At the experimental development version of TheXTech since 29th of March 2022 (The next after 1.3.5.3-1 stable release) is possible to natively customise all internal graphics using the same filename as an original file at the "graphics/ui" directory. You may simply copy a file from the "graphics/ui" directory into your episode or level directory, edit it if you want to, and place it in your SMBX level or episode folder.
