I've looked at different sets out in the internet and I've tried to convert the neo-geo games on my own. All games are running but all of them have some minor sound (esp. music) issues. It's a kind of "clattering" (hope this is an understandable translation).
On the other side my Dingoo was shipped with some Neo-Geo games installed. All of them have much clearer music. And all of them are about 10% larger than the converted ones. Anyone has an idea what I can do to get the other games to run with better music quality? What is the problem with my converted roms?
Just one example for the file sizes of "2020 Super Baseball":
self converted: 6583KB
pre installed on dingoo: 7138KB
what filesize do you have? Btw. this converted file is ok when scanning with clrmamepro and the dat file from this site.
