Hi! I'm the person who created a working BDSX-Dockerimage. :)
I searched the whole Internet and all Forums for Wine-Support and finally got it working after hours of debugging.
Download the working image from Dockerhub and start it with:
docker run -it -p 19132:19132/udp ghcr.io/pokebedrock/bdsx-docker:latest
Go into the entrypoint.sh and uncomment the following lines by removing the '#':
#rm -f index.ts
#touch index.ts
