@Folly said in Only Cartridge Files Loading on Amstrad CPC6128+ (MESS/MAME):
~/RetroPie-Setup/ext/RetroPie-Share/scriptmodules/supplementary
I did not find a second version in ~/RetroPie-Setup/ext/RetroPie-Share/scriptmodules/supplementary, but I deleted any other versions of the file on my system - in the trash folder, download folder, etc...and that did the trick.
I will try the ParaDOS options again later and report back.
The ParaDOS options are visible and they do load ParaDOS.
