The ultimate series, from RGR Game, is the ultimate retro package. There are a large number of HACK games, classic games, childhood games and self-produced games. The capacity is 64G and the number of games is 8,000+. The collection is based on my personal preferences, but this is definitely not the final version, as the capacity is limited and there are far more games than this. In-depth customization of DSTWO MINI OS and WOOD Beyond V2.4 systems. To do this, I created art covers that pay homage to the amazing classic games that were a part of my childhood. Please note that some emulators stopped development many years ago, which is not player-friendly. We have tried using different emulators to experience, but there are still some games that have problems, which is normal.
