Neo Flash cart doesn't work with my new TG16

[incrediblehark]

has anyone found out a solution to this? I'm having problems with my new neo flash and trying to find out a fix.

The current fix is to buy a second console, and hope that it has a stronger HuCard slot.

You might also ask "thesteve," it seems like he was on to something regarding this issue. Either way, it would probably involve sending your system away to be modified, so just buying a second cheap console online might be a better way to go.

i have a theory on this, but would need a problem setup in front of me to test it
I know its not the power supply to the slot, but it could be an interfacing issue, with the data/addressing lines.
especially if the flash chips are 3V logic

I was working on this as well, while I was region modding my system I tried hooking a 5V source to the hucard's 5V pin with a jumper wire, and it seemed to work in the 2 minutes that I tested it, but I definately wouldn't call this a fix since I didn't spend time really testing it.

Long story short, the region mod didn't work, BlueBMW (who knew nothing of my playing with the power) fixed the region mod for me, and when I got it back the flash cart worked 100%, either with or without a Turbo CD attached. Weird.

 The 6280 is known to have weak data bus lines (the address lines are fine). It's possible the region mod acts a transmission line buffer (which specifically fixes these sorts of problems - weak transmission). Rule of thumb on the PCE, you definitely don't want to try to drive more than 1 device with the data bus. It's possible the Neo Flash is doing just that - driving more than one device (an interface IC and some other chip at the same time).

the region mod adds resistance to the data lines 4ohms for the new single chip and 50ohms for the old 2 chip version.
this does slightly weaken the data lines.

well i tried adding a 5v to the hucard 5v and no change, of course it is still most likely my region mod as thesteve suggested before

if your region mod is the 2 chip type try using a higher voltage supply to the mod
