[RESOLVED] Option to change core/emulator dissapeared from some systems

Hi, and first of all, thank you for the great work you've been doing with Retrobat. It's so simple to use and has made emulation something I can really enjoy instead of it being a confusing mess.

Update: Ignore everything, I figured it out after spending more time than I should have spent doing experiments with folders. After testing some roms in a clean RetroBat v6.2.1 installation, I've verified that the ChannelF and Intellivision system never had the option to choose the core. Also, after updating that clean installation to Retrobat v6.3.0, the GX4000 system had indeed the option to choose between cores. I'm editing the post instead of deleting it in case anyone falls for the same thing I did. Somehow.

So long story short, I was gaslighting myself.

Thank you anyway!

I've been building my Retrobat little by little, and I've reached the point in which the only thing left for me is to apply shaders and filters for every system so they can look awesome. I was doing that, when noticed something weird: in some of the systems the option to change the emulator dissapeared. I mean, if I press Select and go to Advanced System Options the section "Emulator" is not even there. I'm pretty sure the option to change cores was there before, but now it's simply gone:

So far, this is happening to ChannelF, Intellivision, and Amstrad GX4000 systems, and I have no idea of what did I do to make that option go away. Some games, like the GX4000 Pang, have some graphics glitches  so I would like to be able to change from the libretro cap32 to the Capriceforever emulator. The option is not there even if I choose the game itself and going to Advanced Game Options.

Any idea of how can I solve this problem? I'm so lost with this.
