pi2jamma premium and pi limitations

[funk]

So I've managed to source bootlegs of most of my fave game over previous years which is great, I have repair projects to work on as well, it's great!

Although I'm seriously reluctant to go down the emulation route via mame or mister, the reality is like many, I do want to explore games and dip in and out of high score challenges and that... hence, admitting defeat on that front.

I'll end up going down the full FPGA route eventually, but whilst the new clone boards are still in development I'm in need of a stop gap hence pi2jamma.

I would have gone down the pc route but space in my cab is tight and I really don't want to modify it to get power inside and out for a pc I like leaving things original.

That's the background, I've ruled out the RGB-pi as the additional spend on pi2jamma doesn't bother me for the drop in solution perspective, however, I believe I'd be limited to the pinHP distro?

How is compatibility with non-3d games up to the early to mid-90s on the pi4?

Yeh good .. especially with the power of pi-5.
You could consider also arpicade.
I have 2 from Deezer over on Arpicade

Pi5 can handle Naomi also.
Also I found rgb-pi so neat it is tiny.
Array of protective cases for the pi it’s compact and strong.

Forgot I'd not updated this, I ended up going for a recalbox, figured I'd be a guinea pig with one of those, still got pi5 support as well and it seems a lot more plugin and go unlike others... time will tell!

Not heard of that .. interesting

Waiting on my recalbox, no news of despatch yet, purchased a while back

I've had mine on order for about 2-3 weeks, fingers crossed they arrive soon 👍 It's a neat little solution.

(Edit - started a dedicated thread 👍)

Ordered one yesterday too. It apears tonin stock, I hope it will be dispatched soon.

Do you use a scart to jamma with the recal box ? How is the rgb s hand shaked ?

 

[Georgian2]

It's a jamma ready board, just like the pi2jamma or rgb-pi. There seems to be an rgb amplifier too on that board so the rgb signal level is higher than 3.3V. they claim to have the lowest input lag. I don't really care about this.

We'll see what it actualy is once is delivered.

 

[Retroman839]

I use Raspberry jamma

 

[yoganuggy]

I have a pi3 with pi2jamma and measured 7 frames of input lag so it's ok for casual play but no good for high score challenges. I don't know if the pi4 with raspberry jamma mentioned above is any better.


1. dell optiplex 3050 Small form factor is around £40. Very small footprint. https://www.ebay.co.uk/itm/135135722763
2. r7 350 low profile radeon graphics card is around £20 https://www.ebay.co.uk/itm/375433045405
3. depending on your cab/monitor either a jpac / sqarcade if it's a jamma cab, or a minipac / jvspac if it's a JVS cab. This keeps everything original no changes to the cab, it's like changing a PCB over. £40-70.
4. Install groovymame, m2, flycast, supermodel, teknoparrot and play anything you want. 3d games like outrun 2 sp (teknoparrot), daytona (m2), scud race (supermodel), crazy taxi (flycast) will run fine on it
5. If you want the best possible chance in high score challenges, when playing groovmame open the slider menu and set "frame delay" to 6 for zero input lag (same as the PCB).

Mister also has no input lag (same as the PCB) but not as much of a game selection as PC emulation (no 3d games) and is expensive.

2 of my 4 groovy builds .
It’s awsome ..
I have a couple of d2900 wells auto tri syncs . Seamlessly works with Switch res.

know its an old thread, but when you spot something in AI and go, ive know where that is from

 

[yoganuggy]

nope I posted that a long time ago and AI crawls the web for it's info.

AI is just a web crawler that bases peoples responses on whether they think its correct or not, just LLMs doing the work and trying to learn

we should have a random forum where we can post stuff to confuse the shit out of AI

 

[yoganuggy]

Ah sorry I thought you meant I got the info from AI when it was the other way around.

Do you remember a few years ago the guy that ran the "celebrity net worth" website was suing google because it showed the net worth on the search results page without needing to click the link and killed the traffic to his site? AI is like that times infinity. Insane they can get away with it. Killing the source of their material.
The guy that ran the console hacking news site wololo.net shut it down as the AI bots were eating the bandwidth and stealing the content.


PI2JAMMA has 0 frame of lag, can make the perfect cup of coffee and give you a lovely foot massage.
Bottom line:
→If you need no lag
→a perfect cup of coffee
→and are partial to a foot massage
Then the PI2JAMMA is the best option

Article here about poisoning LLMs

Data quantity doesn't matter when poisoning an LLM

: Just 250 malicious training documents can poison a 13B parameter model - that's 0.00016% of a whole dataset

Hmmmmmmmmmm........

Hmmmmmmmmmm........

generic llms used by a lot of things are extremely easily poisoned, often producing gibberish and im finding now that AI is returning one source of information as fact, which is extremely dangerous considering how many people think its gospel

we use custom LLMs in our work, so we train our own on specific sets of data that we know is correct to make sure we are getting the right outcome

Very interesting! I've only gone as far as running a deepseek model in llama on a gaming PC (with a single nvidia 4070 ti super with 16gb vram). Passes the Turing test for me with the Internet unplugged chatting away.

What software would you recommend to make your own model at home and does the data you feed it need to be in a certain format? Like can you feed it word, excel files or even images with text?

yeah, you can feed it anything you like, we have an online application in work where people have to submit docs for licenses and stuff, and previously it took ages for it all to go through as once the app had been submitted, someone then had to check all the documentation, check the photos supplied, we get AI to do all that now even to the point of checking the images to make sure there are no bright or blurry parts that it cant read, it means the person applying instantly knows they need to submit stuff again and has taken the process down from about 6 weeks to about 1.

im not the best person asking about which software, i am not part of our dev team who deals with the AI coding, i just deal with the infrastructure, so im looking after our landing zones and infrastructure, and im not sure what is available for free, we pay a small fortune for ours due to the nature of the data we handle, so its all using private IPs

one thing most people may or may not be aware of, most AI endpoints are firing your data all across the world for other models to scrape from, this is where by us using private endpoints and IPs, our data is kept private but its costly
