Bad Tengen Carts? + Is V-V (JP MD) region locked?
Re: Bad Tengen Carts? + Is V-V (JP MD) region locked?
What a game. I have the Grindstormer cart but only ever played the V-V mode. So many great memories of the 2-all
Re: Bad Tengen Carts? + Is V-V (JP MD) region locked?
My old Genesis Grind Stormer cart is beginning to barely ever boot up any more. Occasionally it will work right after I clean it with rubbing alcohol. Most of the time I just get a white screen when I load it up on my Genesis. I think I may take some Brasso to the contacts tomorrow and give it a good cleaning. Intermittently working/not working like I'm describing - does that sound like an issue with the cartridge contacts?

I have a Gauntlet IV and a Paperboy by Tengen that lock up and after investigating found a youtube.

I'm taking my Gauntlet IV to work tomorrow to see if the traces on the PCB can be revived. If not i'm buying a donor cart and switching the chip to a better PCB.
I get the Sega License screen for a second and it drops to a black screen. Paperboy did it as well but I just cleaned that one and it worked.
There is another guy who put his game PCB in the oven for 8 mins at 200c and it worked. But for how long I don't know.

I watched those vids with interest when you linked 'em earlier, ta. So it seems the issue is with the boards, not the ROMs.
I've still not found any mention of Japanese carts behaving similarly... I'd guess they weren't from the same manufacturer, offhand. I would almost open up one of mine to check the board for telltale manufacturer marks, but I can't be arsed figuring out how to do that without mutilating the back sticker. Might try picking up a cheaper NTSCJ Tengen cart to check, if there exists such a thing.

I opened my Gauntlet IV and strangely none of the markings matched. Certainly did not have Tengen or anything like that on it.
A guy at work knows a bit about PCB's so I'm taking it to him tomorrow to see if he can see what the problem is and if it needs a donor for the ROM or not. I think he will use a multi meter to see if the traces pass current. If it fails his tests I will ask him to use a donor PCB. However, looking at the video the PCB's don't look anything alike. The resistor on the Mickey game is not aligned with the Grind stormer cartridge. I hope it all works out. Whatever I find out I'll post it here.
