Hi everyone,
If you face the problem of filtering rom fullset depending on the rom name (containing [!] for verified, (E) for Europe, (U) for USA and all other codes...) like I did, you can use a tool I developped. It is opensource (so free) and feel free to contribute creating pull request or isssues. This is the link: https://github.com/benjdum59/filterRoms
Enjoy!
