Not working for me either. EZ-Flash ODE running on SimpleDE's source. White screen when trying to launch a ROM.
Update: I tried the file (.mb) you uploaded under the issue on github and it works!
I added PogoShell support, it works for me with an old PogoShell but a person on GitHub could not get it to work with EZ-Flash ODE, can someone else try it?
