There is still one remaining Sega Genesis to Atari 7800 controller adapter should anyone be interested.

Yes. And the controller no longer automatically moves to the right. Before the switch it wasn't every time the coleco was powered on that it skipped menu and messed controller. When it did happened I would turn the console off and on until it was normal. But it got more frequent. After the switch it hadn't happened again.

Today I made myself an adapter so I could try the SMS version of Montezuma's Revenge. I used a male db9 connected to a female db9 with a short piece of controller cable. No wire connects pin 7 from male to female and I removed pin 7 from the female db9 plug. I plugged my Genesis controller with the adapter into the console with a Mega Everdrive cartridge, powered it on and quickly realized that the controller didn't work. No d-pad, no buttons. Is this expected behavior? I found I could play Montezuma's Revenge only if I first "select and start" it from my Everdrive cart WITHOUT the adapter. Once the title screen showed, unplug the controller, plug it into the adapter, then plug the adapter into the console and finally press B button all before Joe starts ascending the steps of the pyramid on his own. I mention this because nobody else talked about swapping adapter/controllers to get the game to work during the progression of this thread. Maybe I messed something up.

I did get it sorted out; sockets and replacement chips are in and everything seems to be working. Originally I ordered a 66 piece assorted size sockets kit and it contained the two 20-pin sockets needed. I also had ordered a 10 count of SN74LS541N chips from AliExpress. Of the 10 only 2 worked correctly (thank goodness for the sockets). Not really pleased with that experience and skeptical of the 2 working chips I have since ordered from mouser.ca some reputable chips and sockets. https://www.mouser.ca/ProductDetail/595-SN74LS541N https://www.mouser.ca/ProductDetail/571-1-2199298-6 Thanks you for the tips and links.

Hello, My Coleco has an intermittent problem. When starting a game the skill menu is bypassed, the game starts and the player moves to the right. Cycling the power on and off a couple times and the issue goes away; for a bit. From what I have read on the forum is it's likely the Octal Buffer(s) at U18 and/or U19 are on their way out. Forum advice says to replace them with Texas Instruments SN74LS541 and to socket them while in there. I have no problems sourcing the chips but I have no idea what sockets to use. The instructions say 20-pin IC sockets (0.3” spacing). I get the 20-pin part. The 0.3" spacing has me confused. Is that pin spacing, pitch, socket width. A link to a correct sized socket would be great. I did find a kit at Console5 but the shipping to Canada and the dollar exchange make it a last resort, not first try. Thank you.

Thank you for adding your review of the SaveKey Tidus79001. I am glad you are happy with it. For others who might be curious about shipping costs to the US... - without tracking is $10 as Small Packet - US Air - with tracking is $16 as Tracked Packet - USA I haven't shipped any inside Canada but expect it to be much less using over-sized letter mail option.

3 sold. 1 remaining.

The Savekey plus with the red LED is sold.

I don't know. All I have tested them on is an Atari 7800. I do not have access to any Flashback system. Sorry I can't be more helpful.

2 sold. 2 remaining.

I have 7 Savekey Plus devices available. They were made following the design found here by danjovic. I am asking $5 per Savekey to cover the cost of components and materials. Shipping cost will vary depending on your location. Send me an address and I will calculate it for you. I am located in Canada. Most have blue LED but there are 2 with green and 1 with red. There is a clear and durable heat shrink cover over the board to protect the circuitry while allowing the LED to shine through.

I have 4 Sega Genesis to Atari 7800 controller adapters available. They were made following the DIY instructions found here in another AtariAge post. I am asking $13 per adapter to cover the costs of components and materials. Shipping cost will vary depending on your location. Send me an address and I will calculate it for you. I am located in Canada.

I just followed your tutorial and it worked great. Took under a minute as there was less than half the first line with "not-FF". Thank you.

My error. Seems I forgot to press "reload data" after switching to base 0000. I was able to save this across multiple savekeys... I have read, bookmarked and will definitely try the procedure above to remove the individual high score (Amoeba Jump). Most likely later this evening. I do have one question so far. How did you get the $08C0 to $08FF value for Amoeba Jump? Thank you for making up the tutorial. It must have taken some time and effort on you part. Much appreciated.

Thank you. With Amoeba Jump I was not able to erase the high score completely but could set it to as low as 1. Strat-o-Gems took a couple tries to get the sequence right but did clear from the savekey. I have never been able to get the AtariVox/Savekey Editor to work. I can edit the values but the changes never save. Restarting the atari and the values are back to the pre-edited ones, wherever they came from in the first place.
