Broken User Database

The forum's currently broken user database was already mentioned here: http://forums.nesdev.com/viewtopic.php?f=13&t=20505&start=45#p275026 - I am just starting a separate thread for it... About 50% of the user accounts seem to be lost: When looking at recent topics, one can still see the us...

Re: NDS Cartridge ROM specs

Ah, okay, header[1BFh] is just indicating if (or how many) SHA1+RSA signatures are stored in the header. Apparently Jam with Band JAP was the oldest NAND title (no signatures), followed by Warioware JAP (some signatures), followed by the EUR/USA versions (with full signatures). More interesting: Jam...

Re: 3DS reverse engineering

That reminds me you mentioned how the graphics don't look much better on 3DS games than on DS. That's because you tried the wrong games Probably. I've bought only five 3ds cartridges yet (including two supposed "quality" titles). I've tried hard to figure out which titles might be interes...

Re: Is any input device for Famiom/Famiclon that uses /IRQ line?

Interesting that MMC IRQs aren't open collector, that's making it a bit more mystifying how Nintendo had intended to interact with cart and controller IRQs (if that had ever really considered such things). Nintendo M82 , which is basically a box for many cartridges to be plugged at once and then pla...

Eugene, what are you linking to? That kiwi farms webpage is a troll forum with users hoping that "niggers and faggots" will live-stream their suicides. Please remove the link, or at least add a description and warning what you are linking to and why.

Re: DSi Wifi rev-engineering

DHCP is nice to get IP addresses assigned automatically... unless it doesn't work. I've spent a whole day on trying to figure out why DSi/3DS wifiboot doesn't work with DHCP in my current network. I couldn't find any mistakes in the wifiboot source code, but I've finally "solved" it by mov...

Re: Living and Hacking in a Tent

Got my nicotine flowers all planted well (except 4-6 being planted too close to the river got eaten by snails), now I am curious if they will really grow 2m tall, and help me to avoid the infamous 1000% tax on goods for poor people, if it's working then I'll hopefully pay only twice as much tax as t...

Re: Help with CD drive not spinning

Search the internet for something like "Neo Geo CD repair spindle" there should be some info & forums that could at least tell you if the spindle should spin without disc inserted.

Re: NDS Cartridge ROM specs

I am now doing a Frankenstein firmware dump by merging the best matching code snippets. The dumping tool is searching for a known "anchor" point (the blowfish key, or some characteristic opcode sequence). That does usually find 15-30 code matches, often circa "7D00h(+/-random) bytes&q...

Re: 3DS reverse engineering

Yeah, flickering would cause only "positive" or only "negative" pixels, I didn't knew that a little flickering it could actually damage the hardware. At least it's only temporary burn-in in that case (Sony's Pocketstation seems to suffer from permanent burn-in, it's somehow havin...

Re: NES vertical artefacts after cuted 4th leg CIC pal ver

Any chances that you have cut the wrong "4th leg" on the wrong chip?
And it's having cut, or after cutting, not having cuted, or after cuted (unless you have decorated the mainboard with cute pussycat stickers).

Re: NDS Cartridge ROM specs

Timings Today the 20ms delay after releasing reset isn't long enough, don't know why, maybe it's temperature related. With 30ms it's working again. For ROM data reads, gap1=380h works only 99% stable, but it returns corrupt 200h-byte sectors at 00EC7200h and 018BAE00h. Dunno, maybe that two sectors...

Re: NDS Cartridge ROM specs

I think I have found most Face Training commands, it required some guessing how to use & unlock which commands because the auto-detection fails if the cart isn't in the correct mode (ROM or RW mode, and NDS or DSi mode), and also fails with wrong data length, and can behave differently on differ...
