Bug ID: 45493
           Summary: SRPG Studio games fail to run
           Product: Wine
           Version: 3.13
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: jscript
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

AFAICT, all SRPG Studio (an engine: http://www.srpgstudio.com/) games fail to
run without setting up WINEDLLOVERRIDES="jscript=n".

Lets use Vestaria Saga as an example (download link on
http://site.wepage.com/vestariasaga/page5-02).

Without native jscript, all that happens after launching it is an error dialog
with string 'A-Phese 7'.

The whole of builtin jscript debug log is short and not all that helpful:
