Atariboy2600 Posted February 23, 2022 Share Posted February 23, 2022 Last week I just got the Japan Up/Down converter in order to play any Japanese import systems like Nintendo Famicom or Sega Mega Drive using this converter and tested both Famicom and Super Famicom have a TV set that can get both Channel 95 & 98 to work with any Japanese systems. Now Im ready to bring back any gaming systems from Japan later this year if all goes well. It’s recommended that to use the original Japanese power adaptor that came with the Famicom, Disk System or accessories when playing in the United States or Canada. To do so will require a step-down converter. Quote Link to comment Share on other sites More sharing options...
0078265317 Posted March 5, 2022 Share Posted March 5, 2022 For Super Nintendo no need for all that. Just get a game genie and USA SNES. The game genie has no tabs and will allow the Japan games. Just press start and no codes entered and its as if you never had a game genie. Quote Link to comment Share on other sites More sharing options...
DragonGrafx-16 Posted March 6, 2022 Share Posted March 6, 2022 I just busted the tabs out of my NA SNES... I have no problems with carts being too loose. 1 Quote Link to comment Share on other sites More sharing options...
Tanooki Posted March 6, 2022 Share Posted March 6, 2022 That said, I did. My original system from launch I did that, after using it extensively through its life, by the later half of the 90s I snapped it (1995) and by 4~ years later I had problems with it start to develop where the games could wobble and easily lose contact and seize up, so I eventually had to stuff a little folded piece of paper in there to lock it into place which SUCKED. I eventually sadly parted with it for a SNESjr, then dumped that years later when I got a DK set original(1chip system) locally here. That though even is stored now because of a SuperNT which has no tabs or pins issues. Quote Link to comment Share on other sites More sharing options...
0078265317 Posted March 7, 2022 Share Posted March 7, 2022 Game genies are not that expensive. https://www.ebay.com/itm/144439529488?hash=item21a1445010:g:3s4AAOSwnqFiHoLQ Or this works too for imports. https://www.ebay.com/itm/294825989935?hash=item44a4ff972f:g:wYwAAOSwZ49iE8yz Quote Link to comment Share on other sites More sharing options...
Tanooki Posted March 7, 2022 Share Posted March 7, 2022 Oh yeah I had one of those and totally forgot about it, that weird Nakitek. It is crazy hanging a game out the back like that, but the plastic molding does secure it well and it has the added bits for expanded board games with the big chip sets (SA1, SDD1, C4, FX/FX2) Quote Link to comment Share on other sites More sharing options...
DragonGrafx-16 Posted March 7, 2022 Share Posted March 7, 2022 I dunno why my SNES has no problems with loose games. Maybe it's that I did not completely bust the tabs out... just enough that SFC games can fit. 1 Quote Link to comment Share on other sites More sharing options...
Tanooki Posted March 7, 2022 Share Posted March 7, 2022 Could be. My mom at the time had this "professional" nail file, basically a ladies dremel with various shaped heads like that actual tool uses. I didn't snap mine out, I sanded it down to a smooth finish to match the rest of the tray. 1 Quote Link to comment Share on other sites More sharing options...
eightbit Posted March 8, 2022 Share Posted March 8, 2022 (edited) I wouldn't waste time using the old power supplies with a regulator. I replaced all of those overheating old power supplies (on a Famicom AV and a SFC and many more) with modern 9V center negative pin power supplies: https://www.amazon.com/gp/product/B00D97ZJCA/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I am not sure about the original Famicom and disk system, but I suspect the PSU polarity and voltage is the same. You would have to check. These run cool...they do not get hot. They are USA voltages so you don't have to mess with a converter. Not to mention they are just safer. Systems that I know use this PSU (as I used them personally!): Atari Jaguar Genesis model 1 SNES (with an adapter to allow it to plug in) Super Famicom Famicom AV NES SMS TG16 PC Engine (and variants) It's even the same power supply for my Roland SC-50 synth. The original power supply from that smelled like it was burning when I got it. Edited March 8, 2022 by eightbit 1 Quote Link to comment Share on other sites More sharing options...
Densetsu33 Posted March 9, 2022 Share Posted March 9, 2022 I just got my step down converter for my super Famicom. I have a couple of questions.. The official power supply I ordered looks like it had the same type of plug as the USA version. If I plug it into the 120v socket will it step down the voltage to 100v? I'm confused because the PSU I ordered won't fit the Japanese side of the step down converter. Am I missing something? Quote Link to comment Share on other sites More sharing options...
Densetsu33 Posted March 9, 2022 Share Posted March 9, 2022 Also, what could go wrong if I plugged it in directly? I have genesis model 1 PSU as well. Just weighing my options. The SFC is coming Monday, and I want to be able to hook it up. Any advice would be appreciated. Quote Link to comment Share on other sites More sharing options...

It may appear to work for a time (or even a long time) but it WILL damage your equipment. I learned that the hard way a very long time ago. Just replace those supplies with what I linked.

Unless you are nostalgic for power supplies.... I have a 9v center negative power supply for a model 1 Sega genesis. Should I just use that? It is rated AC 100-245V 60hz Output DC9V-850mA. Its a new power supply. Edited March 10, 2022 by Densetsu33 Quote Link to comment Share on other sites More sharing options...
Densetsu33 Posted March 10, 2022 Share Posted March 10, 2022 (edited) I just got my SFC today, and I plugged it in using a Genesis model 1 PSU. It is rated for 10v so it more closely resembles the original adapter. It is working well and not running hot. I am slightly concerned about the extra 20v. I don't know if that is an issue in the long run. Edited March 10, 2022 by Densetsu33 Quote Link to comment Share on other sites More sharing options...

I've been using a model 1 Genesis adapter for about a week now and it works fine. It is 10v DC. Some model 1 power supplies are 9v if I'm not mistaken.

eightbit Posted March 25, 2022 Share Posted March 25, 2022 (edited) I am not understanding why you are concerned about using the 100V power adapter with converter at all? As I mentioned, you can use the adapter I linked via Amazon or a Genesis model 1 adapter. I think there is some confusion here. The console is not receiving 100V or 110V. If it were, well, you would not have much of a console anymore..lol! It is receiving 9VDC via a 5.5mm barrel connector with a center negative pin. The power from the wall socket is the input whether it be 100V (in Japan) or 110V (in the USA) and it is outputting 9VDC to the console. Even if you do not understand how the power is working, rest assured you can use 110V USA power supplies (again, like the one I already linked!) with these consoles and you will not have to deal with these ridiculous converters.

I don't understand why you think I'm confused about the voltage the system uses. My question was concerning the setting with the step down converter. Anyways I believe it is 10vDC. I'd rather play safe than sorry with this old equipment. I have been using a model 1 adapter for the time being. It works but I'd like to use the original adapter personally.

Anyway...If you want to continue use the original old Japanese 100V power supplies (or any decades old power supplies) I am not so sure you are playing "safe". But, to each their own. I already gave you very sound advice on what you should do to help prolong those machines...so whatever Edited March 25, 2022 by eightbit 1 Quote Link to comment Share on other sites More sharing options...

But the ones you linked were 9VDC. The super Famicom is 10VDC. I'm sure that they work, but I would be more likely to buy them if they were the right voltage. I primarily use an FX pak pro which draws more power than a normal cartridge. I'll look around and see if I can find an adapter with the recommended voltage.

You are still confused - the SFC is going to take that 10V DC and run it through a 7805 and turn it into a steady 5V. Don't worry about spending more money on a step down convertor or other power supplies - you already have what you need. Quote Link to comment Share on other sites More sharing options...
