The console doesn’t officially support ROMs. It must run games off the original hardware carts.
However, there’s a fairly simple hack to get ROMs to play on the SD card slot of the Analogue Pocket that many suspect was unofficially developed by Analogue themselves.
Yeah, but again, try running on a platform of “everything you enjoy will need to be different.”
Oh sure. I agree with that. Obviously many people have limited options.
I just think think it’s a monumentally bigger ask no matter where the change has to be made (policy or individual choice).
Like our best solution for transportation (in the US at least) is to just keep making larger free ways. Even gas powered buses running on decades old technology could make a significant impact on the climate crisis, but people either don’t want to ride them or cities don’t want to build them.
Any way, I’m just frustrated with the attitude that we’re going to technology our way out of this hole without needing to change or sacrifice anything (like we pulled off with ozone).
When it comes to energy use, there’s such a thing induced demand. If it’s cheaper, people will use it more. Hell, look at how much energy it takes to use AI to write an email.
There’s no induced demand with refrigerants.
Yeah but consumers already have choices when it comes to fossil fuels and they’re sticking with fossil fuels.
Eh. The solution to the ozone layer was to replace refrigerant A with refrigerant B. A 1:1 swap that required very little effort from anybody.
Getting off fossil fuels more or less mandates an entire global paradigm shift in how we do basically everything. The entire global economy of the past 200 years has been built off an unsustainable energy source.
Sure, we can replace gas with batteries, but every step of the way is going to require small changes in how people do things, and they’re going to be very resistant to that.
It’s a lot of work. At the end of the day, I spent about $1k to get about $100 worth of gold, so it’s really not lucrative. I just wanted a fun story behind an engagement ring.
I actually mined the gold from electronics and those gold plated Pokémon cards they sold at Burget King for Pokémon the Motion Picture, but that’s another process.
Here’s how it goes:
Clean up your electronics. You ideally want just circuit board contacts. Like the strip of contacts on a stick of ram. Cut/break those off and dispose of the rest.
Soak in copper chloride. Use Hydrochloric acid (sold as concrete cleaner) and hydrogen peroxide. It’ll start eating at the copper on the circuit boards. 2HCl + H2O2 + 2Cu -> 2CuCl + 2H2O
Keep dissolving. This part takes a while. It helps to use a stir bar and bubbler to keep the fluid moving. CuCl will eat more copper and produce CuCl2, but you can “recharge it” by adding more HCl and bubbling in oxygen (or use hydrogen peroxide, but that’s more expensive).
Now you should have a bunch of flakes of gold that was plated onto the copper as well as the bare circuit boards floating around in a dark green solution of copper chloride. Pour through a coffee filter and wash with water to remove all the copper chloride.
To recycle the copper chloride, mix with sulfuric acid (sold as battery acid). CuCl + H2SO4 -> HCl + CuSO4. Boil off and condense the HCl to re-use. You won’t be able to get “fuming” 30% stuff like you buy at the store because the azeotrope of HCl is 20%. Then you can plate out the copper from the copper sulfate and reuse the resulting sulfuric acid. Copper sulfate is a super pretty blue by the way.
You do copper sulfate because plating copper out of CuCl2 will release HCl gas which is nasty.
Filter through another coffee filter and distill resulting solution to recover HCl and H2SO4.
Dry the filter paper, ball it up, and toss it in a heated crucible (I used a blow torch) with some borax to act as a flux. Eventually the paper burns away and you’re left with a tiny bead of gold.
So yeah, you can reuse the copper, Hydrochloric acid, and sulfuric acid, and the other byproducts are harmless salts and gases.
As someone who has personally mined 2.5g of gold from old electronics, I can confirm that while messy, there are no toxic byproducts.
In my setup, the only waste was hydrogen gas, CO2, and NaCl.
Of course I preprocessed my electronics to remove any solder or components, and you’re still left with the bare fiberglass circuit boards, so it may be different on an industrial scale.
Oh right, duh. Thanks.
I believe the optimization came because the denominator was a power of two. In my memory, the function counted up all of the bytes being sent and checked to see that the sum was a multiple of 16 (I think 16 bytes made a single USB endpoint or something; I still don’t fully understand USB).
For starters, you can split up a larger modulo into smaller ones:
X = (A + B); X % n = (A % n + B % n) % n
So our 16 bit number X can be split into an upper and lower byte:
X = (X & 0xFF) + (X >> 8)
so
X % 16 = ((X & 0xFF) % 16 + (X >>8) % 16) % 16
This is probably what the compiler was doing in the background anyway, but the real magic came from this neat trick:
x % 2^n = x & (2^n - 1).
so
x % 16 = x & 15
So a 16 bit modulo just became three bitwise ANDs.
Edit: and before anybody thinks I’m good a math, I’m pretty sure I found a forum post where someone was solving exactly my problem, and I just copy/pasted it in.
Edit2: I’m pretty sure I left it here, but I think you can further optimize by just ignoring the upper byte entirely. Again, only because 16 is a power of 2 and works nicely with bitwise arithmatic.
Lol, no, but in the summers we were allowed to wear t-shirts on Friday.
Thanks!
And it was. They told me to take the rest of the day off which at the age of 22 was unheard of.
Thank you! But this was 12 years ago lol. Think they’ve moved on.
Whoops. Formatting got lost in the transfer. Fixed now.
What’s funny is that’s how it started. Apple sold movies as early as 2007 before Netflix or Amazon video or whatever and expected you to host the files locally either on your computer or your AppleTV (which had a hard disk drive at the time) and stream it locally over iTunes. If you lost the file, that was supposed to be it.
Of course, you still had to authenticate your files with the DRM service, and eventually they moved libraries online and gave you streaming access to any files you had purchased.
Yeah, but we always run them in native formats, so it’s not a big load on the processor. We only watch the 4K stuff at home where it’s got a hardwired gigabit ethernet connection.
If you saw my other comment, I’m kind of talking myself out of this upgrade since I managed to get qsv working on my current rig.
That shouldn’t be the case. I’d look into getting this fixed properly before spending a ton of money for new hardware that you may not actually need. It smells like to me that encode or decode part aren’t actually being done in hardware here.
Right you are!
Dug into it a little more. There were some ffmpeg flags that weren’t being enabled by the latest release of Photoprism. Had to move to the test build. https://github.com/photoprism/photoprism/discussions/4093
While it’s faster than real time now, Photoprism still won’t start streaming until the preview is fully generated, so longer video clips can take a minute or two to start playing. It only has to happen once per file, but it’s still annoying. There’s a feature to pre-transcode video, but it’s only to get in to a streamable format. It doesn’t check bitrate/size until you actually start to play.
I might write a script to pre-generate the preview files, but either way, I don’t think I need to upgrade the server quite yet.
Yes, but you still need to install the cores developed by the community in order to play ROMs.
The necessary core for ROMs was released barely a day after OpenFPGA support was, but it wasn’t released by Analogue.
