i had an old acer aspire one lying around that i installed mint xcfe on. i hope to make it into a mini chiptune/tracker station. however, I seem to be having issues with installing emulators (like KiGB) and LGPT. Whenever I run these two apps/executables, nothing happens. Any linux-savy people willing to help me out?

I've never heard of KiGB, but I know retroarch has a couple cores that work for LSDJ: gambatte, SameBoy, TGB Dual, mGBA, Emux. For LGPT try running it in a terminal and seeing if it gives any errors. For that KiGB if it's not installed and it's a binary, make sure it has executable permissions and if not run a chmod +x on the file?

Either use Gambatte, or BGB in Wine.
