Swiss Updates – August 2020

The Swiss team has just published another few revisions of their GameCube software.  As always, they’ve continued to improve overall system stability and tweaks have been made to help slower SD cards perform better;  Some adapters were causing issues with games like Soulcalibur II, which is sensitive to interrupt latency.  Also, FMV stutter with SD Card Adapters has been almost completely eliminated.
