hey guys. i have 2 genesis model 1s non tmss that both wont work with my 32x. the 32x works fine with my model 2 and xeye so i think it might be the adapter cable for the model 1 causing problems but im not sure. my issue with my non tmss consoles is the entire screen is completely green, i can still see the games and read text etc but everything is green. do any of you have a non tmss model 1 that works fine with the 32x? if so i will have to buy a new cable on ebay. thanks
The adapter is an rgb cable. If red and blue disappear somehow, you're left with green In fact 32x requires the console output rgb. (it won't officially work on consoles like Laseractive) Are you using a Sega CD, or the slot extension thing? Some combinations of 32x and system are finicky. Possibly more so with an empty Sega CD slot. http://www.sega-16.com/forum/showthread.php?12881-Whats-this-for&p=278401&viewfull=1#post278401
thanks for the response. im not using any slot extension stuff, just the console itself. the patch cable works fine with my model 2 and xeye so im starting to believe its my model 1 adapter for the patch cable causing the problem. this thing: i was wondering if anyone could confirm they've successfully used the model 1 non tmss with the 32x. once i know that then ill basically know i need to buy another cable for my model 1.
i have mine on a VA3 non-tmss japanese Mega drive, it works fine. your adapter is likely shot. get a multi-meter and verify the connections if you want a definitive answer. that would be your best bet.
I see I'm late to the party, but I just wanted to second that I have always used my 32Xs on my launch model Genesis 1 HDGs non-TMSS and they have always worked fine. Hopefully the new cable works. Have you tried using RGB Scart on your Genesis 1 before?
There are two versions of the 32X hardware. VA0 32X units require a MEGA/SEGA-CD or the termination plug in unit which comes with it connected to the expansion connection of the Mega Drive/Genesis unit to work properly. VA1 32X units work fine without the plug in or a CD unit. You can figure out the version of the 32X unit looking at the slits inside the cartridge slot prong which connects to the Mega Drive/Genesis cart slot. VA1 32X will have "VA1" visible through one of the holes.
Then what's up with my 32X? It's a VA0 and works fine without the Sega CD or the termination plug on my VA6.5 Non-HD Model 1 Genesis. Is mine actually a mislabeled VA1?
The VA1 unit has 10K pull down resistors on data lines and capacitors to smooth the clock signals, which are not present on the VA0 32X... Basically the termination is installed into the 32X Va1. I believe that the termination is important because SH-2 should default open bus to zero not one like other systems usually default open bus to... So, you won't really notice problems with Mega Drive games, it will cause problems only with native 32X games. Meaning that reading 0xFFFF from open bus could cause faults on a 32X game which expects open bus to return 0x0000 instead. Pertinent information, here: https://console5.com/wiki/32X After I applied the fixes described on the service bulletins to my Mega Drive unit, the 32X stopped giving me crashes with Space Harrier. Which was awesome.
Indeed, it does not. I have a USA VA3 board but I had crashes and music frequencies drifting while playing 32X games. I applied the fixes and the crashes/glitches went byebye.
Sorry, I didn't realise you were talking about 2 different things. Just confused me, assumed I was missing something or there's a document I was seeing etc.
My bad. I should have added that, if the user has a VA0 32X and no termination he/she may experience crashes and glitches. Using the terminator on a VA1 32X will have no effect. In my case I had glitches but I had a VA1 32X and no reasonable explanation for the glitches. I did not need a termination device, for example. So all I could do was try the service bulletin fixes. And indeed, applying the fixes from the service bulletin solved my problem even though the fixes were not meant for the board my unit has.
i missed the new responses, the new patch cable did the trick, the 32x works fine with my non tmss i was asking about. the 32x is making some high pitched noises lately though, hope the capacitors aren't about to pop! a lot of my old consoles are failing lately, maybe partly due to using everdrives with everything.
There's a buck converter with a inductor and a switching IC + transistor to bring down the 9v from the supply for the 32x into the 5V and 3.3v it needs for the video chip, the SH2s and the SDRAM it has inside. If the inductor is cracked or a capacitor is bad the inductor could indeed whine as the buck converter oscillates.
not yet. maybe sometime in the next few days or i might also just pack it up for now. play some more 32x later down the line.
