mGB locks up on a blue grid

Running v1.3.3 on a GBC using EZ Flash Jr. See attached image v1.3.2 works fine.

My GBC does the same thing as yours when trying to load mGB v1.3.3 via EZ Flash Jr. cart.

Same ROM on same cart works fine with my DMG.

Previous version of mGB on same cart works fine on both.

I'll check my EZFJ cart firmware when I get home. I got it earlier this year and flashed the latest available fw to it.

So i recently tired on a Nanoloop cart - and it seems to work fine - so must be some issue with the EZ Flash Jr for whatever reason.
