New Dingux build available for download in the OP.
I took the time to update VICE for the Dingoo A-380 to version 2.4.6. I also fixed the sound so we don't need the slow filters anymore. This only works with Custom frequency 16000Hz and Fragment size Very large. The Buffer size is set at 64 msec to remove the remaining static sound as much as possible without slowing down the sound.
There's still a sound bug in VICE or SDL but there's a work around for it so read the
Note in the OP.
As a result we now have a Commodore 64 emulator for Dingux that emulates almost every game at full speed with good sound.
