I just got the SMBX Integration config, and PGE still won't launch a test correctly. I press "Test in SMBX" and SMBX launches to its splash screen. When the editor starts up, the level doesn't open, and the LunaTester thread stays busy. Then, I terminate the thread, and SMBX closes.
Is there a way to have the splash screen be skipped and go directly to the editor? This would probably improve it a bit. Of course, if this is the way you go, you'll need the launch options (Disable Frame Skip, Disable Sound).
I think SMBX should stay open after the test. I mean, doesn't it seem weird to close it and then have to wait for it to load for every test?
