Not sure if i worded this right, im fairly new but I loaded a bunch of roms into the mame 4 all rom folder via ssh and they all play fine and show up with the simple names on the list But when it asks me to scrape i go through the process most of them show as green/verified then i go back to mame4all and nothing is scraped. No images and no full names.
check and see if /home/pimame/pimame-menu/.cache/mame4all.cache is there. (the .cache folder is hidden). it's all stored in plain-text, so you can even open the file and check the contents of it.
