Do you know why VICE does not allow .PRG files to be loaded on the RG 350? All other versions of VICE load these files and some games are only available in that format.
I don't use VICE, I have no idea.
For FBA do you know how to get sound samples to work (Donkey Kong etc)? Also if I just want one icon (for setup/vertical mode) how do I get rid of the other one as I don't need that and it just confuses things (the one that uses system browser)?
Samples should go to $HOME/.fba/samples
You can get rid of icons just by removing associated .desktop file in OPK (in your use case, it is fba_ux.gcw0.desktop).
To do it, you need OpenPackageCreator :
https://github.com/Harteex/OpenPackageCreator/releases- Use this command to expend opk :
unsquashfs.exe fba.opk
- Remove anything you don't need in created directory named
squashfs-root- Build your new opk with this command :
mksquashfs.exe squashfs-root fba_new.opk
That is quite easy.
