Re: Need help about gameboy pin30 /reset signal

I think your math is a little off (the time constant looks to me like it's somewhere around 15ms, so it's an unexplained 13nF, but 13nF is still too big to be plausibly on-die in late 1980s technology) I would say the time constant is closer to 20 ms (two divisions) but around that ballpark, yeah. ...

Re: Need help about gameboy pin30 /reset signal

It may not be the LR35902 itself, but there's definitely something keeping /RESET from rising until 8.6ms after +5V has stabilized: That looks weird. 1) How the power seems to rise linearly rather than converge exponentially. (Capacitor charge curve.) 2) How the /reset signal DOES have a capacitor ...

Re: Rom Laboratory 404

ROM Lab. works again. I contacted the owner and the mirror to the site was wrong. http://romlaboratory.dbwbp.com/ Could you contact the owner and link them to my post about character encoding? The auto detection fails on Firefox, and uses windows-1252 instead of windows-1250 which garbles some char...

Re: Rom Laboratory 404

FARID: You may want to deal with the page encoding for example on this page. The page seems to be Windows-1250, aka Central European (Windows) and shows up as garbled from here. The auto detection, at least in Chrome, would have worked except that the web server declares that the page is UTF-8. Even...

Re: Need help about gameboy pin30 /reset signal

/reset is an input on the CPU. It's weakly pulled up to Vcc with something like a 100k resistor. Probably, your FPGA is sinking the voltage too low. Try adding something like a 10k pull-up on your cart and see if it improves stability. grounded by the LR35902 until it's ready to start executing code...

Re: Software licenses that ban porn and blasphemy

I had 26 cats and they cuddled so cutely and warmly. I'd like to share that without getting a reuptation of being some kind of a freak just because the verbs and nouns that I use have been defiled. If you had 26 cats, that would probably give you a reputation of being a freak without the help of ru...

Re: Nintendo switch gets hacked with webkit exploit

smea's comment was obviously tongue-in-cheek. The point is that anything that's using an old version of Webkit will have a bunch of freebie userland vulns.

Re: Nintendo switch gets hacked with webkit exploit

Smea's tweet from a couple of months back seems relevant enough.

Re: ROM hacks now in Nintendo's crosshairs

Bottom line, get into a fandom that supports derivative works under a normal common sense copycenter license I think you're misunderstanding what copycenter means. Copyleft means that there are restrictions in the license to force derivative works to stay copyleft, thus ensuring that they are avail...

Re: Input lag in emulators

The reason to make a dedicated test ROM would in my opinion be two-fold. 1) Guaranteed behavior. some games may for whatever reason not react consistently to input and might have lag in some states but not others, skewing the test. This is conjecture on my part, but it would be better to eliminate t...

Re: ROM hacks now in Nintendo's crosshairs

The IPS patch itself, provided it has no infringing contents... ...as long as it doesn't contain infringing data itself... That's the big if. In this case, it seems they included pokémon and/or other elemebts from later generations, so that in itself means infringing material. It also seems to be c...

Re: Google autocorrects NesCartDB to ROM sites

It's not "autocorrection" per se, it's what might be described as aliasing or collation. If you search for something like bike, it will also include results for bikes (ie plural or other grammatical variations) as well as bicycle and other synonyms. Google considers some terms to be equiva...

This is the same model Autodesk is using for every other product in their portfolio. While perhaps offensive to "us", it has to be a well thought out business model, or Autodesk is doomed as a brand of industry standard industrial design software for a variety of specialized fields. Have y...
