=== Known issue ===
Several Tengen published games for the Sega Genesis have high failure rates. There is an apparent issue with the 800068-01 REV A PCB where at least some experience a loss of via conductivity with time.<ref name="Via Repair">https://www.reddit.com/r/Megadrive/comments/ep2p93/i_found_a_possible_easier_fix_for_broken_tengen/</ref> Not all of the games which use this PCB seem to have high failure rates, so it might be restricted to certain batches which would be identifiable by the date code printed in copper on the top side of the PCB.
 
=== Symptom ===
Games affected are often completely non-functional. The issue can be confirmed by measuring resistance between the contacts on the "B" side of the edge connector and the corresponding pins on the ROM chip. An unaffected board should measure below 2 ohms, while an affected board will give a resistance that can be as high as 100 ohms which varies pin to pin. In some cases the vias may be fully open circuit.
 
=== Note about name change ===
Tengen was renamed to Time Warner Interactive in the middle of these boards being produced and sold. This article will refer only to "Tengen", but TWI branded games may possibly also be affected.
 
==List of potentially affected games==
While the 800068-01 REV A PCB supports 16 megabit ROMs, Tengen also used it for smaller games. In some cases, these boards were even fit with 40-pin ROM chips, leaving the two holes on the pin 1 side empty. It appears that there was a period where Tengen switched to using this board for most of their titles including ones that had previously shipped with Sega-branded boards or the 40-pin 800057-02. Thus, games in this list may or may not use the affected PCB, depending on age. Additionally, later "cardboard box" releases of these games use Majesco-style cartridges with yet another PCB design.

==Known affected PCB date codes==
For the purposes of this table, a board is "good" if '''all''' vias measure less than 2 ohms, and "bad" otherwise.

==Clean the vias==
If the vias are cleaned, the game will boot.<ref name="Via Repair" />
 
Pick one of the possible cleaning tools:
*Leg of a component, such as a resistor or capacitor (this in particular is a perfect fit for the vias)
*Needle
*Dental pick
*SIM tray tool
 
#Open the cartridge with a 4.5 mm gamebit screwdriver to gain access to the PCB. Remove the PCB from the shell.
#Use the tool to make sure the all the holes are clear. Simply push on the tool until it comes out through the other side.
[[File:Grind Stormer Vias.jpeg|600px|Vias]]
#Clean PCB with compressed air and 91% or greater isopropyl alcohol.
#Reassemble cartridge and test. If the game behaves erratically, freezes up after a while, or still does not boot, repeat the process until it works reliably.


There were several Tengen Sega Genesis games that had a design flaw that causes almost all of the PCBs to fail over time.  
This solution should keep your game working for a long while. Unfortunately due to the flawed nature of the design, it will likely fail in the same way again. At that point you can simply clean the vias again.

==Repair the vias==
*Grind Stormer
The vias can be repaired but will require the ROM chip to be removed and replaced afterword. See this [https://www.instructables.com/Repairing-Plated-Throughholes-and-Vias-on-a-PCB/ guide] for how to repair vias.
*Dragon's Revenge


==Replacement PCBs==
Todo: John Rigs claims that these PCBs are designed to work without capacitors? No evidence provided as to why this is safe? Anyone know anything about what these capacitors are for?
Replacement PCBs https://www.vgcables.com/product/sega-genesis-replacement-pcb-rom-cartridge/


The rom chips can be swapped to a donor game's PCB. All 1GB games should be compatible.
==Replacement PCBs (not recommended, last resort)==

Note that in the video, John Riggs claims that these PCBs are designed to work without capacitors, but it is highly recommended to add them so the ROM chip receives clean voltage.

Summary

Grind Stormer PCB
Grind Stormer PCB rear
Corroded vias

Known issue

Several Tengen published games for the Sega Genesis have high failure rates. There is an apparent issue with the 800068-01 REV A PCB where at least some experience a loss of via conductivity with time.[1] Not all of the games which use this PCB seem to have high failure rates, so it might be restricted to certain batches which would be identifiable by the date code printed in copper on the top side of the PCB.

Symptom

Games affected are often completely non-functional. The issue can be confirmed by measuring resistance between the contacts on the "B" side of the edge connector and the corresponding pins on the ROM chip. An unaffected board should measure below 2 ohms, while an affected board will give a resistance that can be as high as 100 ohms which varies pin to pin. In some cases the vias may be fully open circuit.

Note about name change

Tengen was renamed to Time Warner Interactive in the middle of these boards being produced and sold. This article will refer only to "Tengen", but TWI branded games may possibly also be affected.

List of potentially affected games

While the 800068-01 REV A PCB supports 16 megabit ROMs, Tengen also used it for smaller games. In some cases, these boards were even fit with 40-pin ROM chips, leaving the two holes on the pin 1 side empty. It appears that there was a period where Tengen switched to using this board for most of their titles including ones that had previously shipped with Sega-branded boards or the 40-pin 800057-02. Thus, games in this list may or may not use the affected PCB, depending on age. Additionally, later "cardboard box" releases of these games use Majesco-style cartridges with yet another PCB design.

Incomplete list of Tengen games confirmed to use this PCB:

  • Grind Stormer (US)
  • Dragon's Revenge (US)
  • Gauntlet IV (US, EU)
  • RBI Baseball '94 (US)
  • Awesome Possum (US)
  • Hard Drivin' (US)
  • Kawasaki Superbike Challenge (US)
  • Lawnmower Man (US)
  • Red Zone (US)
  • Steel Talons (US)
  • Rampart (US)

Known affected PCB date codes

For the purposes of this table, a board is "good" if all vias measure less than 2 ohms, and "bad" otherwise.

Date code Known bad boards with this date code Known good boards with this date code
9338 Yes No
9341 Yes No
9343 Yes No
9349 Yes No
9429 No Yes
9439 No Yes
9444 No Yes

Clean the vias

If the vias are cleaned, the game will boot.[1]

Pick one of the possible cleaning tools:

  • Leg of a component, such as a resistor or capacitor (this in particular is a perfect fit for the vias)
  • Needle
  • Dental pick
  • SIM tray tool
  1. Open the cartridge with a 4.5 mm gamebit screwdriver to gain access to the PCB. Remove the PCB from the shell.
  2. Use the tool to make sure the all the holes are clear. Simply push on the tool until it comes out through the other side.

Vias

  1. Clean PCB with compressed air and 91% or greater isopropyl alcohol.
  2. Reassemble cartridge and test. If the game behaves erratically, freezes up after a while, or still does not boot, repeat the process until it works reliably.

This solution should keep your game working for a long while. Unfortunately due to the flawed nature of the design, it will likely fail in the same way again. At that point you can simply clean the vias again.

Repair the vias

The vias can be repaired but will require the ROM chip to be removed and replaced afterword. See this guide for how to repair vias.


Replacement PCBs (not recommended, last resort)

Note that in the video, John Riggs claims that these PCBs are designed to work without capacitors, but it is highly recommended to add them so the ROM chip receives clean voltage. Replacement PCBs: https://www.vgcables.com/product/sega-genesis-replacement-pcb-rom-cartridge/

The ROM chip can be swapped to a donor game's PCB. All 1 MB (8 megabit) games should be compatible.
