Goodbye, 1.5 kernel? - Image 1Over on Dark AleX's website, it seems we're about to give a fond farewell to the kernel that's been a part of the homebrew scene for the longest time: the 1.50 kernel.

Alek, one of the admins of dark-alex.org, posted a recent entry detailing the means by which one could adapt what they know into the 3.xx kernel era. In his entry, he writes,

Due to the almost sure probability to abandon 1.50 kernel on future releases 'cause of better compatibility and security on 3.xx/4.xx, some new devs were asking me how to port their knowledges to 3.xx kernel, and of course also their own apps.


He advises them to visit this particular ps2dev entry by CpuWhiz (external link) in the hopes of porting what they've already done to 3.xx functionality. Furthermore, he explains,

But anyway, does this change to superior kernels is necessary? Indeed it is. It allows a greater range of thinks (sic) that can be done, plus solving tons of problems on 1.5 kernels. Therefore, having the oportunity (sic) to use this ones with the actual cfws, why not to do so? Open to debate.


It's an exciting time for the homebrew scene, seeing as there's new technology coming out and people are learning to adapt to the new ways of doing things. While most people will certainly miss what can be called "the good old days," we can certainly look forward to what homebrewers have in store for us using the newer kernels.

Thanks to Gilberto Jimenez for the tip!

this story is old...really old

great though, no reason to have a phat anymore besides the ir port

 » confusing stuff....explanations please

does this mean that we will no longer be able to play SNES, N64, games on firmware 4.0 or above..or are they trying to mix the 1.5 kernal into other firmwares to no longer need to do a 1.5 kernal add on in to future cfw

   Re: teh not so 1337 g@m3r - 2008-06-25

It means no those SNES, N64, etc emulators will no longer work, unless they are upgraded by their developers.

We can play SNES and N64 emulators fine with the 3.xx kernel

1.5 is useless.

   Re: xche78x - 2008-06-26
 » im a slim user too

1.5 kernel maybe useless to slim users but there are still lots of homebrew and homebrew makers only available for the phat machine so its not useless at all.

i agree that we can run most emulator homebrews on 3.xx kernel but i must say that remaining 1.5 kernel devs should also update to the newer better kernel to reach a wider audience.

no need to have the phat
yeah da is telling everyone to dump their phat and buy a slim

theyre saying goodbye to the kernal not the phat
also i do believe that the slim still has trouble with some HB, were as the phat deosnt have as many problems on the exact same kernal

anyway they say goodbye to 1.5
and i say goodbye to DA CFW

seriously unless all devs release all previous apps for the new kernal, or we wont have much of a scene
either that or release the source

The only thing the slim has problems with is the HB with ir capabilities.

The 3.XX kernel version of PSPFiler has troubles with USB dumping and a few other bugs. IRshell has problems loading some ISOs and apps, as well as running USBhost and Nethost on the 3.XX kernel version.

This may be a hint to the upcoming utopia kernel. Perhaps this kernel can replicate what 1.50 could.


   Re: Bolec - 2008-06-26
 » hm..

I don't think that there will be any use of utopia kernel.. considering that it won't have any GUI and it will be aimed into devs.

Now do you think 1.50 kernel has a GUI? LOL!
   by 73N5H1 - 2008-06-25
 » its about time....

there's no reason that anyone should have a problem with this. The facts are:

The slim can only run 1.5 kernel homebrew using time machine and even then, there is a chance for incompatability

The phat can run both 1.5 and 3.x/4.x homebrew with no issues whatsoever.

So dropping the 1.5 benefits the Slims by forcing future homebrew to be 100% Slim-compatible, and has no effect on the phat, that can run 3.x homebrew anyways.

The only effect this has is making (Very) old 1.5 homebrew incompatible with newer CFW. And most older homebrew has already been ported to 3.x, especially the popular programs. The only effect is if you're running some obscure little known legacy homebrew that hasn't been ported to 3.x. In which case, you can probably find another (more recent) 3.x homebrew that does the exact same thing.

   by kittykat - 2008-06-25
 » One word: ELoader

Of course, there is always the ELoader program. I have used this on a PSP Slim and have noticed that it loads at least 90% of all 1.50 kernal games/apps, and seems to work equally well on all custom firmwares (so far).

Of course, the ELoader does need further development in order to boost its compatibility, so perhaps those who are still fond of the 1.50 kernal can collaborate and tinker with it a bit in order to iron out the kinks and defects. That will lessen the pain of losing the 1.50 kernal and keep people from complaining about it.

   by 73N5H1 - 2008-06-25
 » forgot about ELoader

perhaps a group of HB programmers could even offer a forum where users could submit 1.5 kernel homebrew to be re-encoded for the 3.x kernel...

Utopia.

 » lame

Don't hate on me you slim-fanboys, but I don't see this as a good thing. I'm not updating to any firmware that doesn't support 1.50 homebrew. The fact is -not- all homebrew has been ported to 3.xx kernels and some of it may never be. Hopefully this "utopia" kernel will make this distinction moot.


   Re: majorbb100 - 2008-06-25
 » i kinda agree

i might not update to this because of that very reason. I seriously hope that some other dev will release his own 1.50 kernel for 4.00 M33. and if it works well then i will for sure. This will take some thought.

   Re: RudedoggX - 2008-06-25
 » That's cool, man.

If you don't want to upgrade, the answer is simple - don't upgrade. No one really cares if you do or not.

   Re: JaXeRiR - 2008-06-26
 » @dark420bishop

Tell me even one homebrew that hasn't been ported to 3.XX or doesn't have an application already on 3.XX that does the same thing.

Oh well *waves goodbye to 1.50 kernel

 » why?

why the hell are they not making that kernel anymore i mean does it really hurt them to make them? let the guys who want the kernel do what the wanna do with there kernel issue's and i really hope someoene could actually make a kernel for the cfw coming! like the people of gen maybe? wel you know what i think ... psp slim sucks ..!


   Re: Goobers - 2008-06-25
 » hum...

support for 1.50 is what exactly? so old HB can work?

people have already mentioned alternative ways to getting those apps to work.

and it DOES HURT THEM... because you can't support something by just dumping it in... you have to program for it and bug test it. it's a lot of time and effort.

i can understand that some apps are popular, but if you're updating those apps and/or creating new ones, why force people to use 1.50 compatibility, when as a dev, you can allow higher firmware compatibility? which allows for more possibilities, since there will be features you no longer have to mimic, and the new firmwares give you access to newer things that 1.50 doesn't.

in my opinion, i think people that lock into older "versions" are poor programmers, period. no one takes that crap on windows/linux/mac based apps... why take it here?

 » GREAT!!

I stopped updateing to 1.5 kernal months ago. This will save a lot of download time

   by xLinkinwormx - 2008-06-25
 » this is good

because the phat psp was running out of space because of the use of 1 newer kernal which will always get bigger, the custom stuff like ISO loading recovory menu ect, so the 3mb or so of no 1.5 kernal will be awsome news only thing is i have some homebrew that wont ever be updated to 4.xx kernal because of how things are.

omg some of you still play with a phat psp?

you must hate using diagonal directions while playing games. my ears arent on my lap either. (always wondered why they pointed away from my face.

dont forget if your emulator doesnt run its the authors fault not the psp slim's...

thanks m33!


   Re: 3vi1 - 2008-06-27
 » omg some of you still drive last years model of car?

Not everyone wants to buy a new $170 toy when the old one's not broken. I could go out and buy a slim right now if we wanted. There's just no compelling reason to do it:

Want to move diagonally? The game probably supports the analog stick for that. I'll admit that I mostly just use my PSP to play emulators of games from my youth, but diagonal movement has yet to be an issue for me in any game.

Ears not on your lap? They're not on your stomach either. My PSP is loud as is - I wish there was an extra volume level between off and the lowest (especially when running SNES emus) - I'm kind of glad the speakers are where they are. But, if I wanted it to sound better or louder, I'd just plug in the headphones.

Skype? I've got a cell phone with better features, and my company foots the bill.

TV output? I have a PS3, Wii, 360, and HTPC attached to my 55" TV, why in the world would I want to look at the PSP on it?

Infrared support? Why would I wan... oh wait, I love that feature, and it's only on the phat.

So, the way many people use their PSP, the slim's still a downgrade at this point. Now, if they ever come out with a model with a HD in the place of the UMD and enough memory to run a real Linux distro, we'll talk upgrade.

What about pspvlc player for streaming live tv, dvd's, tvuplayer. As far as I know it won't work without 1.5 kernel. PspVlcPlayer is so good for watching live tv on psp and no way do I want to lose it. Alot of people have never tried it but it works perfect for me.
Hope 1.5 will be coded into future firmwares without need for a kernel.
As far as I know pspVlc player is the only app for live tv streaming from your tv card.

 » time machine

Try using the time machine 1.50/3.40 kernel on the slim. Pimpstreamer (the 1.50 version) works with TM, willing to bet pspvlc works too.
   by eddib - 2008-06-26
 » Excellent decision

Since I bought my slim, I've had no need for the 1.50 kernel. All the homebrew I ever need has been ported to 3.xx kernel. And those odd ones that haven't, I use the ELoader which does the trick very well (for my li'll zookeeper fun).
And at last some clarity for the developers, they'll have to make one version only.
Besides all that I really don't see why so many people are clinging to the 1.50 kernel or even 1.50 FW. Move on people. Its just useless old nostalgia, get over it!


   Re: 3vi1 - 2008-06-27
 » Agree

I have a phat with both kernels but as I've been playing my old emulators I upgrade them from the 1.5 version to the 3.x versions.

Most of the 1.5's have issues with the soft power-off anyway, so it's more convenient to run the 3.x version.

 » recall the DTV "black sunday kill" before you read, or look it up

1.5 on a fat is really so far the only way own your psp for certian. If you break off that path and let 1.5 go, you risk falling into the hands of sony and it's code unknowns..

We still have time machine for the slims of course, but remember that the slims were engineered and designed to run with a firmware no lower than 2.8 or so.. better check it, perhaps it's already owned by sony right out of the box...

Lets hope we're not going to end up looking back on this time and say "well we thought we could do it, but then we lost it all and had to do something else, if only we had kept it, we had all moved on to our new systems, but now its ruined.."


sony wants to fight piracy, they've been doing their research on cfw and it's users, and they're selling a lot of slims.

imagine if they are harnessing the hacking scene to sell units, and send a massive attack via a firmware/wi-fi future event they had planned, that captures the majority of it's users and then charges a fee? or else just fry your system. you get the point

you DID recall the black sunday kill, didn't you?
