The Dangers of using 3.3V Flash Carts in Retro Consoles

[Black Tiger]

Xbox has lots of nice 2D games/compilations and almost always supports progressive scan, while PS2 almost always doesn't.

There are still cool non-anti-human games like Panzer Dragoon Orta, Jet Set Future, Outrun 2, Psychonauts, Beyond Good & Evil,

Outrun 2 (via 2006), Psychonauts, and Beyond Good and Evil were multiplats. I didn't care for Jet Set Radio, so I never played JSRF.

Yeah I replaced my PS2 Capcom classics with the Xbox version awhile back. I need to do the same for Taito Legends. I believe TL2 is EU only for Xbox.

Related: I don't understand how people keep buying Assassin's Creed games. But yet Ubi is like...15 games deep at this point? Something absurd. It shames yearly sports titles honestly.

Couldn't the same be said for Call Of Duty, Battlefield, Halo, etc?

Also, there were six Mega Man games on the NES alone, so there's nothing new with endless sequels.

I'm not disagreeing that there are too man Assassin's Creed games. I played the first two when they came out, then Black Flag years later. I'd recommend BF if you haven't play an AC game yet.

Yeah, I'm pretty sure I hate all of those games. The XB was really good at that stuff, the sort of anti-human style-free depressing brown crap that goes on and on for hundreds of hours. The sort of stuff that now describes almost anything that isn't Nintendo. Oh God, how I hate this kind of shit and all the nearly identical covers with a personality-less bad ass standing in pile of wreckage with a green tint to everything.

You forgot Star Wars: Obi Wan, btw.

Yo guys, don't forget about Otogi 1&2, Kung Fu Chaos (dumb, but fun), Voodoo Vince, and Blinx 1&2.
I really love all of those games, and they've got plenty of color and life to em.

also, how come no one talks about bloodwake? It's Twisted Metal on boats.

[Gypsy]

I remember Blinx annoying me but I did finish it.

UPDATE: Bernie just informed me that he had a NEOFLASH cart inserted in his DUO (power switched on) when the plastic housing of his DUO *MELTED*.

Are you talking about the hairdryer thing, or has Bernie actually lost two duos that way?!?

Two DUOs

I suspect a THIRD DUO might be in danger as I type this.

Pray.

Krikzz just posted this.

db-electronics predicted huge current leaks and flash overheat. According to his prediction, carts without voltage translators should draw 12.5mA current for each IO. Ok, so, 16bit databus should draw then 200mA. I made small measurement for old EDMD-v3. I checked full console+cart power consumption, difference was around 25mA total, and this difference mostly due the normal power consumption of own cartridge components.
So, my question is: Where is huge current leaks predicted by db-electronics in his sensation article, or where is large amount of heat? Seriously, i can even make video with thermal camera if somebody still believe in overheating. Just touch chips by fingers and you will feel that all everdrive chips is cold and all console chips just a little warm, same as with original carts.

[ClodBuster]

All of krikzz claims don't matter as long as his stuff is running outside of the specifications.

If he would be as eager redesigning his flash carts to comply with the chip's and console's specs as he is in denying simple facts...

Argument with solid data and sound theory

Just touch it with your fingers!

 

[ClodBuster]

Exactly. It's like discussing with "audiophile golden ear" guys - a waste of time and brain cells.

[SamIAm]

But Rene is the one proposing a theory while Krikzz actually measured something.

I mean, we're not going to know until someone checks with an oscilloscope on an IO pin, but there clearly isn't a constant 200mA of extra current being sucked through the data bus. There might be more than 25mA going through there if the components on an Everdrive pull less current off the power rail than a real cart...but I could just as easily believe that the reverse is true, and that that's where the 25mA is coming from.

The next thing I'd be curious to see is how much is consumed during flashing, and how that compares to the ratings on the flash's datasheet.

[ClodBuster]

It doesn't matter what current flow krikzz has measured, since the components are still getting more voltage than the specifications allow.

Also, the components in krikzz' products aren't properly driven by proper components that translate the voltage to the correct levels. Instead, he is relying on ordinary series resistors, and as it turns out these are not the proper design for this purpose. This has been discussed before in this thread.

[SamIAm]

Yeah, but I don't think people are anywhere near as concerned about their Everdrives being damaged by overvoltage as they are about their consoles being damaged by current flowing in large quantities where it shouldn't be.
