Weird MegaSD woes - not booting in a 32X, random crashes using the MSDEXP

[+jgkspsx]

This probably isn’t the best place to post this, but since the TerraOnion forums are gone and I havent registered at Sega16 yet it will have to do.

 

I have been having some serious trouble with my MegaSD lately. It won’t start up at all in my Genesis/32X stack. It works fine in my MegaSG, but when I run it from the MSDEXP adapter some games constantly crash. Robo Aleste was fine, but I could hardly play Sonic CD for five minutes before it reset back to the Sega CD boot screen, and Popful Mail crashed with a CPU error in the intro cinema.

 

Has anybody seen this or heard anything about it? Is there anything I can do? It seems that I am out of luck for 32X CD games for now unless I get the real SegaCD out of mothballs.

I can't really say much other than that mine works fine on all of my real hardware, though. Try cleaning the cart and the cart slots. There is also a new firmware update, so try running that on the Mega Sg.

Msdexp use of the MegaSD is hit or miss on model 2 units right now. Model 2 Va4's seem to work ok, but va1.8, 2, and 2.3 can have issues. There is some timing issues depending on which ASIC is in the unit. Model 1s all seem to be ok as well. They are working on the model 2 issue, but haven't found the magic bullet yet.

 

Unfortunately Sega bodged and modified the Genesis hardware a ton, and no one really knows what actually changed in the way things worked.

Well, the crashes happen on a Mega SG. I was able to confirm that after upgrading the firmware of both devices Popful Mail still crashes.

The MSG seems to follow the timing of the affected model 2 units more than a model 1, so you probably will have issues through the expansion port until the timing fixes are done.

Do CD games work through the cartridge port with the 32x removed from it?? also join their discord feed. alot of people are on their talking about 32x CD compatibility right now.
