Over the past couple of weeks, the Xbox One was blessed with some retro love courtesy of Hamster Corporation's ACA NEOGEO series. The company has now brought the series to the Switch with a few titles, but there appear to be some issues cropping up with the release.
According to the Hamster Corporation Twitter account, there seems to be problems with the audio in some of these new games where the sounds are slightly delayed. Furthermore, the firm also states that there is an issue on the video front where the images displayed might be too bright. Luckily, there is a fix coming and the update should be released sometime next week.
For the time being, it looks like you can still download the games from the Switch's eShop. If you are not seeing the 'ACA NEOGEO' titles, there is the possibility that it has not been released for your region, but you can use the workaround to access the games. The Hamster Corp. website does list that five titles from the ACA collection are available.
