GRIND STORMER for SEGA GENESIS, how the heck can you fix these faulty carts?

[sonicsju]

Faithful gamers of Sega's 16-Bit wonder know very well of "Grind Stormer", a Toaplan shooter published by Tengen.
They also know that a huge batch of the US/NTSC release was made very faulty, and have ended up as "dead carts".
Sadly I own two of these "dead carts", but I would like to know if anyone has discovered a way of fixing these?
No cleaning agents, "q-tips dosed with rubbing alcohol" or even "brasso" will revive these carts, I have opened them and discovered there are a few resistors on the cartridge itself.
Does anyone think these resistors need replacing?, and if so, does anyone know which ones to replace them with?, or know how to perform this operation??

any ideas will be helpful..

Thanks so much!!!

Re-Flash the Eproms.

Oh god, they were printed on EEPROMS? Jesus, why would they do that? and here I was assuming that the game was expensive because it was rare.

Actually, I have no clue.

Apparently they were very poorly made for some reason and a lot of the carts are dead.  Far as I know there's no way to fix them.

Hmm, sounds to me like I need to track down raw Cover, Manual, Label scans and get myself a CIB repro. Why invest the money on something rare and expensive if its just gonna crap out on you and reprogramming the eproms (making it a repro anyway) is the only way to repair it...

If you decide to get a repro done let me know. I have grind stormer cib so I can get you the cover and label

There have been a number of request for Grid Storm. Will you scan it please. After all these years of ignoring the helpless cries from Grind Storm fans.

That would be awesome dude! Not sure when Ill get one (probably sooner now) but if you can send the scans over, I can get them ready for myself whenever I do!

a couple years ago i got a copy of grind stormer at a flea market for $3.  i was ecstatic.  it was unreal.  i mean, one of the best shooters on the genesis, and a pricey one at that, for a measly three bucks?!  woo!

got home, plugged up my genesis, put in that cart, and hit the power switch.  black screen.

i got one of the dead carts

fortunately i just picked up another one from work for $6 since someone priced it out not knowing what it was

What causes them to die? I know you can erase eeproms by exposing them to light, but the carts should block all light from the chip.

I should ask a few more people and find out why they die out like this.

[BadChad]

Maybe the use of really low quality eproms, resulting in some sort of memory loss over time? Possibly something like them not beeing able to handle the power of turning the console on and off over time maybe wiping them clean at some point? Im no expert, but I could see those beeing possibilities...

Retail carts don't use flashable chips.  UV exposure won't affect them at all.

[scaredtowake]

from what i remember, there was actually a defective batch sent out and sold that were non-working from the get-go.

Really? Then what's the difference between EPROM and a well, a ROM?

I though by definition, EPROM means E.Rasable R.ead O.nly M.emory.

Man, I need to brush up on my cart info.
