Thanks for testing chart45.
I tested on my Super ADAM (plays all SGM games without the SGM) and the games didn't work at first, but did when I tested them again a couple days later. If I try them on my other ADAM (regular that doesn't play all SGM games without the SGM), I'm pretty sure that I will experience the same issues like you did.
My guess is that both of your Memory Consoles will report a "Revision 80" chipset (turn on ADAM and press CONTROL and R keys at the same time before doing anything else and a new SmartKEY will display with the revision #) like the two loose consoles that I use all the time, so an older revision ADAM isn't the issue. Actually, an older revision ADAM shouldn't be a problem anyway since the ColecoVision Delta Board didn't change over the lifetime of the ADAM (that I am aware of), only the ADAM Logic Board went thru numerous revisions/changes.
If you dump the games and place them on the AtariMax Ultimate SD Cart, then both games should work fine on the ADAM that couldn't play them. If you can test this and report back that would be great. If they play fine via rom image, then it has to be a matter of not clearing RAM/VRAM.
