ares v130

 多平台多機種模擬器 ares 發布新版，更新如下 :

ares v130 has now been released.

The most notable changes to this build are the addition of Nintendo 64DD emulation and support for Parallel-RDP on macOS.

Universal Binaries are now available to macOS users, so Apple Silicon users no longer need to self-compile for best performance.

Many emulator cores have also had significant improvement, please see the changelog for full details.
