This may come accross as stupid, but I need to know (to tell others).

Is it worth downgrading to 1.0 from a homebrew development point of view, besides not needing the kxploit folder, like, is it possible to make "better" homebrew for a 1.0? Or are the two the same?

Thanks for your time.

**soccerPMN** · 07-06-2006, 02:49 PM

The only advantage to 1.0 AFAIK is that 1.0 has absolutely no protection on apps, which means it could be possible to modify an update eboot and run it ( I think) but that would still be extremely risky.

That's what I had thought it was, thanks

In short, No. There's no 'advantage' besides running non kxploited eboots. Also, since the toolchain comes with the 'make kxploit' command, it's really not a big deal.

Downgrading to 1.0 doesn't make one an instantly better coder either, and I doubt anything amazing will come out of this.

The only thing that seems interesting is the fact that you can run unsigned .prxs in the flash0, so some sort of custom firmware may seem somewhat plausible.

I'm not rushing into downgrading though since there's really no need to. We could always just emulate 1.0.

EDIT - it seems that 1.0 infact, CAN NOT, run unencrypted .prxs. So really, there is nothing special besides the no kxploit thing.

**bossmanuk** · 07-06-2006, 04:08 PM

If there's nothing that good, I'm staying on 1.5!

**Electro** · 07-06-2006, 04:12 PM

ive also heard 1.0 launches games a few seconds fatser than 1.5

This is true, I don't know why though. Probably since there is no security?

Or because the KXploit has to load a second eboot.

possibly, and shoot, the number of games I play... those couple seconds can add up to hours you know :P

I am actually excited about a 1.0 downgrade, it would be fu nto say that I have a 1.0, and i really want to get rid of those stupid corrupted data icons.

My question is, would you have to mess with the eboots? Or could i just run the 1.5 homebrew without the BLAH% folder?

**cooldocy795** · 07-06-2006, 05:33 PM

Well, some programs are made specifically for 1.5. Like X-Flash. And some shells might use 1.5 specific .prxs or other files.

**beverage** · 07-06-2006, 05:35 PM

ah, that is true, and another thought, 1.0 was only japan PSPs, so does that mean no english?

You would need to convert all your homebrew in order for it to run on 1.0. The non BLAH folders eboot is just the .elf, and the BLAH% folders eboot is the param.sfo, the icon0.png, and whatnot. You would need to merge them together for it to work on 1.0.

It still supports English. My PSP was ordered online from playstaion.jp the day the PSP came out. So I would know.

**Samstag** · 07-06-2006, 11:27 PM

Developing with PSPLink will let you compile and run code much faster than you can with 1.0 from the game menu. You don't have to kxploit your code and you don't even have to transfer it to the PSP to try it.

**Art** · 07-06-2006, 11:45 PM

I'm interested to know why a lot of existing homebrew like PSPRadio reported not to work on 1.00.
I'm definately interested in testing.
The no kxploit idea is nice, but if there are programs out there that don't work on 1.00,
and developpers have moved on, and may not bother to update them..

ITS NOT A HASTLE WHEN U HAVE SEIS PSP TOOL

**Art** · 07-07-2006, 12:08 AM

Did you guys read in the tutorial that 1.00 always runs the PSP at 333Mhz? that is bad if it's true.

it seems to me, that if it can't run unencrypted .prxs the downgrade is rather pointless.

who wants to save a few seconds - when you have to mess about with the eboots in order for hombrew to work with it - surely it will take longer than a few seconds to convert it.

shame really.

i was looking forward to custom FW

**Mister Chief** · 07-07-2006, 04:15 AM

Just use no kxploit.

In regards to using the tool, it is still a hastle. Expecially when considering nearly all homebrew comes prepackaged as 1.5 only.

**Master Inuyasha** · 07-07-2006, 07:13 AM

Yeah, but as art said, its still pretty interesting why some homebrew requires 1.5, even though they are very close, except in the terms of security. Would you like to shed some light on this matter slasher? Also, how do you know it cannot run unsigned .prx?

EDIT: I can confirm that the PSP runs eboots faster, my thinking is because it doesnt have to load other files in order to work. Now, about the 333 MHz thing, if someone can point me to a program where you can see how fast, regaring the MHz the PSP is currently running. I can run tests as long as I dont have to touch the flash of my PSP.

**mnky** · 07-07-2006, 07:14 AM

1.0 is usless anyway, its slow and not as functional as 1.5.

**Master Inuyasha** · 07-07-2006, 07:23 AM

Lets see, if you want to talk about in terms of speed, when you load up 1.0, i can say that yes, it takes about 1-2 seconds to load up at the XMB, why, I do not know. But that time is saved when loading homebrew. As it goes straight to loading the homebrew. And 1.0 is not useless in my opinion, I like 1.0 and Im staying there, hopefully RunUMD will work soon....

I suppose the reason 1.0 can't load a select few 1.5 homebrew, is because maybe 1.5 has some modules which 1.0 doesn't? Perhaps these homebrew rely on the modules that 1.0 doesn't offer. That's just a wild guess, but I don't really know the exact reason why.

I know 1.0 can't run unsigned prxs directly from the flash(thus shattering the custom firmware myths), but it can run them threw homebrew. Freeplay mentioned 1.5 needs to use some sort of dodgy method to load them threw homebrew on 1.5. Although I'm sure it's built right into the sdk(because from my experience with prxs, they worked fine on the regular loadmodule/startmodule commands), so it's not a problem for most people.

As for that mhz check thing, I can make something up for you if you want.

This answers that question as to 'why' the 1.0 PSPs launch games, UMD/homebrew, faster then 1.5.

Use logic and add it all up now

**Slasher** · 07-07-2006, 08:10 AM

Just run this, and it'll tell you what your cpu speed is

**will1234** · 07-07-2006, 08:21 AM

i made one earlier slasher in another thread.

**Master Inuyasha** · 07-07-2006, 08:50 AM

Yeah, the myth of 333 is broken. 1.0 PSPs run on 222, just like any PSP. Whoever said that didnt know what they were talking about.

Thanks anyways. Well, im staying at 1.0, i like it!

**liquidtenmillion** · 07-07-2006, 11:44 AM

1.0 is inferior. It is slower, buggier, has LESS compatibility with homebrew, and offers absolutely NO benefits to 1.5 to the user, and also to the dev. No reason to EVER use it.

1.0 is just as incompatible with custom firmware as 1.5 is.
