We write the year 2025, December, and the Hatari Core in Retroarch is still not up to date, based on Hatari v1.8. Will i use this? NO.
But i will use in most cases RA with all his glory bezels, read ips & HD images, Multidisks/m3u, Gamepad support, virtual Keyboard... which all this can not be done with the RA Hatari core. I found an alternative/replacement for the older Libretro Hatari Core. Its called hatariB from Brad Smith (many thanks). It based on Hatari v2.5 (2024-04) and is running fine. It can be found at hatarib
