Hi all, since I figured it out how make the saved data work on CH, I am going to write the steps that it worked for me.
Replace the bm2dx.dll to the fix one here.
1101300-1101301_fix.7z
Make sure the asphyxia core is the latest version.
If not, update to the lastest one.
https://github.com/asphyxia-core/asphyxia-core.github.io/releases/tag/v1.40
Make the folder for asphyxia as this.
And make sure you have the right plug in for CH
iidxcasthour.zip
Extract the whole folder to plugins folder.
Turn on Asphyxia and change bind to 0.0.0.0
Save the setting and restart Asphyxia server.
Generate a new card.
Right click on the runme.bat and edit.
RnuMe.bat
Copy the card number and paste it to the runme.bat file
Make sure there is no -ea
Disable camera from spicetool
Make sure you leave everything else unchecked and blank.
Turn the game on with runme.bat and go to test mode and change the shop name to whatever and save it.
And go back to game mode and it should now be able to run the card without the network error.
