In case anybody is interested, I bought my SMS YM2413 adapter from Bock last year. The sale thread is still up, so I would suppose he is still selling over email. I had a little bit of trouble with my 1986 model SMS, but he helped me figure things out over email. -edit- Ack, I just read the SMS power thread, those are gender adapters not YM2413 expansions now.
I suggested EverGear and EverBoy, but Igor said he wants "EverDrive" to be in the name of all products which I understand.
I knew that, what was I thinking. Master Everdrive and Gear Everdrive or GGEverdrive seems like the only options then. A play on Everdrive works really well for the Master System, as does EverGear though. :banghead: Out of curiosity, is there any reason why the Master System Everdrive wouldn't work flawlessly in a Game Gear using the Gear Master adapter?
i never seen such adapter, but i think that sms cart will be work on gg if somebody have sms to gg adatper
As far as I know it is just a cartridge adapter working pin for pin with a pin on the Game Gear side getting grounded to enable SMS mode - just like the Power Base Converter. There are at least three different Game Gear revisions that I know of which may potentially pose a problem given one revision is just a PAL model and the other two differ in chip packaging (one versus two). I don't know of any games that have a problem with one model over another but there is the matter of having TV tuner functionality only working on certain models. Could potentially be an issue for this EverDrive.
It was originally called "Master Gear" but now it is called "Gear Master". It lets you play SMS games on a Game Gear. I wonder if the Master Everdrive would let me load and play Game Gear roms while hooked up to the Game Gear.
Nice to hear that SMS BIOS check has been taken care of. Interested to know if GG games would work through the SMS cart w/Master Gear. Might have to wait for someone who has the Master Gear to test it though.
the seciond modle is made by majesco and dosnt even support the tv tunner or other cartiage assorys for the GG so there might be some serios issues with a EverGearDRIVE
No the one and two chip ASIC models are Sega made, as is the PAL rendition. I completely forgot about the Majesco Game Gear so that makes 4 different revisions known with Obama knows how many different Majesco PCBs are out there.
Master Gear adapter (and any clone adapter) PHYSICALLY puts the Game Gear in SMS compatibility mode by asserting a special pin on the GG cartridge port side. When asserted, this signal litterally transforms the Game Gear in a portable Master System i.e Game Gear games cannot work properly in this mode (limited color palette, different IO, etc) and same goes for a SMS Everdrive with GG roms. Only possibility would be hardware modifications to the adapter (for example, a switch that control assertion of that special signal). This would also be a good feature for the GG Everdrive to support that signal, which is pretty similar to SMS support on Mega Drive, with even better compatibility (Game Gear can handle all SMS video modes, including SG-1000 video modes)
somebody know which pin used for switch between sms/gg mode? or may be somebody can make a photo of gearmaster pcb?
http://www.smspower.org/maxim/Documents/Pinouts pin42 is what you want (it's active LOW i.e 0V = GG mode, +5V = SMS mode) ;-) if you are doing this, note that SG-1000 games on Game Gear require CRAM to be initialised (contrary to a real SMS which uses hard-wired color palette), you can find a modified BIOS and infos here.
The only solution I have heard is to replace every surface mounted capacitor with electrolytic ones of the same rating or higher. I was 3/4ths of the way through doing it on one of mine when I managed to rip the plate off the board for one of the caps and couldn't get anything to stick there again.
I'm sure hoping you aren't following your own advice, but you're close. You need to replace them with the same EXACT capacitance (measured in farads) but you can pop in a HIGHER voltage rated capacitor. To do anything else will likely screw up operations. Replacing them doesn't fix the screen's brightness rather it allows the thing to simply function again. The backlight has a DC->AC inverter that knocks up the voltage for the cathode tube. In all likelyhood in this case the tube is starting to go. Thankfully you can remove the tube, remove a few components and take out out the inverter as a whole. I've experimented with replacing it with LEDs but I simply haven't found any that are bright enough and can cover the entire back of the screen as well as a solid tube did.
Yes, the same farad rating, but equal or higher voltage will work. Sorry about that, I assumed KRIKzz could handle that part. I have seen the screen brightness improved by means of cap replacements though. In fact, I was told to replace the caps first before worrying about the backlight, unless the light is just out that is. I think it was Kendrick over at nfg Forums, also of Rec.games.video.Sega, that told me this method works. I'm just not patient enough to replace that many caps in one job.
