- There is no need to use such old versions of MAME
- Retrocade datfile should be availble in Logiqx's older emulators datfile collection
- if that old version doesn't use -listxml or -listinfo but a different command to extract database (what I doubt), you can try to modify engine.cfg to use the old command.

Solution: create a datfile manually by using -listgames, -listroms (which I think was supported back in these days)
