A DC output of the same value and current aka 12VDC 5A...IS THE SAME..REGARDLESS OF HOW IT WAS GENERATED.have you examined DCs under an osciloscope.
And look for what? AC ripple?
"Oscilloscopes will not usually load down the circuit you’re testing because of their high input impedance, but oscilloscopes are designed primarily for waveform observation and are generally less accurate than other types of testing equipment commonly used to measure DC voltages. One advantage of using an oscilloscope is its capability of monitoring the amount of AC ripple voltage riding the DC voltage; this advantage makes an oscilloscope perfect for troubleshooting DC power supplies with excessive ripple resulting from component failure."
You only need a multimeter to measure DC voltage...and yes...I use a multimeter to measure DC voltages all the time on motherboards...like that MSX in my thrifting thread I'm still working on. -

we are talking about PCs, not laptops. stop running away,

my point being not all DC are the same. its not a continuous current. its like AC, with less alternatings. -

You won't use "thousands" of peripherals as it is. Give some examples of emulating not being 100% accurate for PC games.
Like, be honest: Once you have the desired hardware in the 486 you aren't fucking with it anymore. If you say otherwise you're either a tweaker or lying. -

Lag is the obvious one. Timing issues, without the real hardware it's impossible to get timing 100% accurate.Like, be honest: Once you have the desired hardware in the 486 you aren't fucking with it anymore. If you say otherwise you're either a tweaker or lying.
Lol, I have computers OLDER than 486 era ones that I fuck with near everyday.
My Amiga 1200 is right next to my main PC, along with my Amiga 2000, ZX Spectrum and Pentium 1 PC...no tweaking required.
Off camera I have a C64 hooked up to my TV. -

I'll knock the dust off the illegal mexican maid every now and then yes...though like every ass, it's gotten old now. Think I might need to go by the "day labor" site and pick me up a new one.
ETA: My blue Amiga 1200 is still waiting on the black Keycap set I backed on Indigogo about 2 fucking years ago. -

Your question is as juvenile as a 4yr old asking "why" to every response a mother gives him.
"son that's your willy"
"why"
"because it is"
"Why"
"you were born with it"
"why"
"you little motherfucker shut the fuck up before I beat you to death"
"why" -
2021-08-20 at 5:08 PM UTCThere's no such thing as wrong questions, only wrong answers.

I think you clearly misunderstood what I was saying. You aren't taking it apart and putting different cards and shit in it every day.
There's no lag either. You have shit hardware if you think there is. -

? emulation isn't hardware dumbo...emulation runs on hardware..ALL emulation has lag/timing issues...might be very small but it's there. Emulation is never 100%. It's also not relevant to people who like to fuck with the hardware itself.
While it may be theoretically possible to have a 100% perfect emulator, that feat is very rare (if not nearly impossible), even for some highly regarded emulators such as higan or kevtris's work on the various FPGA-based consoles by Analogue. Just because an emulator claims to be "cycle accurate" or "100% compatible" does not mean that said emulator is flawless. This even includes situations in which all emulator accuracy tests (ie. PS1 Tests) are passed, as these tests cannot cover every single edge case, and some of these tests may even fail on real hardware, leading to even more confusion. Some things are nearly impossible to perfectly emulate, such as some of the illegal opcodes of the 6502, where the results are completely unpredictable on hardware, and different hardware revisions have different results and different illegal opcodes. The closest one could get to writing a perfect emulator would be if someone were to exactly copy an original ASIC map or a decap onto an FPGA, and even then, that isn't always a magic bullet.

Just scored that beautiful keyboard for $24
We might be turning the old girl on next weekend.
