So, you are reporting you also get the graphical glitch, but a little later in the level? People that don't read all the way through are going to miss that. It happened on both the Everdrive MD & the MEDPRO on a Sega Genesis Model 1 VA3 & a Sega Genesis Model 3 VA0.
Also, you are reporting a glitch as well, just happens slightly differently. Are you on NTSC or PAL? What model?
