Good ol days ! <| sep |> I was actually thinking about this a few months ago when I got started back up on my old account . Randomly passes by my mind when I ' m there every once in a while now . <| sep |> Any chance you know your goalassist to game ratio with him ? Looks so good especially that strength and pace combo <| sep |> I assume you have the experimental version , and Arcade is visible in the side panel ? If so , make sure you download Mame ROMs version 0 . 149 as other versions may not work . Also , many games are dependent on other ROMs , so understanding these dependencies is key . For example , Final Fight World is 1 . 4 M , but Final Fight US is only 52 k . That ' s because Final Fight US only contains the few minor differences between it and the world version . So when downloading a game , a good general rule is to download the version with the largest size . Another thing to point out is that some games have a BIOS ROM that needs to be installed . For example , Neo Geo games such as Metal Slug , King of Fighters , Shock Troopers , etc need the ROM for Neo Geo BIOS or they won ' t work . When adding games to the library , select Arcade in the sidebar , then just drag the ROMs , into the main window .
