Hello World for PSP

Congrats! I'm gonna use the pic as my background :) Keep up the awesome work..

BTW, not like I have any real clue what I'm talking about, but I think that fooling with the ghost file is probably the next step.. (not like this hasn't been said, but... damn, I'm exited...)

did you take that pic oopo? i just found the same pic at psp-hacks. or did they take it from you.

The pic on psp-hacks.com is from ooPo's original phototake. As ooPo had to shut his site down due to heavy traffic, I don't think he mind.

However, I don't like psp-hacks.com/psp-hacks.net and every other fan site posting missleading news. About that elf2pbp and pbpunpacker, thouse two apps has nothing to do with nemnem's work, these two simply unpack the pbp (which ooPo wrote a program months ago for) and cat's the files together. They may be usefull for some people, but they shoulden't be considering needed apps for the PSP homebrew scene, which people may believe now.

Quick question for those who have this all working - I have found a PSP 1001K to buy, is there anyway to tell if this will work or not? I know the original japanesse ones were PSP 1000K.. so is this a jap PSP with a patch?

Post by **blackdroid** » Fri May 06, 2005 6:17 pm

best way to be certain is to go into system settings -> system information and read the System Software version string.

edited post to reflect Nem, and not Oopo, thanks for the pic anyways oopo :-p. Now we need to work out a way to either make this happen on 1.5 or get 1.0 back on?

None of the PSP-1000Ks are 1.0. You will need a PSP-1000, but watch out, the new ones are 1.5 Make sure you email the seller and ask if it is 1.0.

Thanks qubitz - the seller couldnt tell me what it was and didnt wanna open the box. I have found a place with a demo one (with def v1.0 firmware).. which they might sell.. hopefully..

Another q. To the people who made this - is the elf a normal ps2 elf? Or something a little modified?

hi i dont know if this has already been done, but i took a video showing it on my v1.00 psp. enjoy, sorry for the lack of quality but i took it with a ps2 eyetoy cam, and just put a mic on the side for sound.

Thanks for you all :)
Discussions and infos in this forum enabled me to make Hello World.

There are some inquiries about source code. Here you are:
http://anon.ug.to/sec/pub/hellopsp_src_Rel1.zip

To build the code, I used ps2dev toolchain for PS2. There is no devtool for PSP yet.
PS2 and PSP both uses MIPS cpu and there's some machine code compatibility. You can not use some PSP and/or C code features with PS2 devtool, but for testing it is enough.
A lot of things to do.

That's exactly what I've been thinking. I've been using Elf2PBP to convert a few PS2 apps this morning, and haven't had any success, but I think it might be because I have a 1.5 US PSP. If anyone like to try a converted ExecFTPS ELF (PS2 FTP server) on a 1.0 PSP, I'll provide the link.

For those wondering, it does appear in the MemoryStick game menu, and it does launch, but it comes back to the menu with an error. (The same thing that happens when you launch nem's Hello World on a 1.50 PSP)

I'm not sure what you're trying to do, but you cannot run PS2 binaries on the PSP. nem is using the ps2dev compiler with special flags to compile PSP programs. This works because the compiler supports enough MIPS processors to generate code seperately for the PS2 (default) and the PSP.

Jordan · Post by **Jordan** » Sat May 07, 2005 2:20 am

Right, I understand that, but it could be worth a try to try and execute this on a 1.0 PSP.

...but then again I could be way off and not have a clue what I'm talking about, =)

I hope you know that you are on your way to the Hall of Shame for an unwritten rule. :P

unfortrunaly this topic is too hot to be placed in the hall of shame =P.

to: Nem thanks for the code.

Now its time to figure a way to get this working on v1.5. =S

yeah! psp have direct framebuffer access, it rox !

skippy911 · Post by **skippy911** » Sat May 07, 2005 3:22 am

Hi all,

First thanks to nem for getting code to work. Now on for my question, what can I use to convert bitmaps into the correct format for the psp? I tried using ps2is image editor but the pallete is all wrong when I view it on the psp :-/ Anyhelp would be greatly appreciated.

Thanks

Thanhda · Post by **Thanhda** » Sat May 07, 2005 3:24 am

http://www.segger.com/emwingscbitmap.html

try googling bitmap to c

also try dreamgl, they have a bmp to c converter as well, but its not in short.

nem · Post by **nem** » Sat May 07, 2005 4:09 am

The bitmap in the code is 5551 formatted short. You'll find in the code how rgb is assigned to. I do not know about tools. I wrote some small code to convert the image.

Orion_ · Post by **Orion_** » Sat May 07, 2005 4:28 am

mmh o_O
I found 1555 0BGR using the image of your source code.

Great work Nem :) Wish I had 1/3 of the brains you do to do this type of work :)

Can I ask in what direction your going now with this? any other idea's you are working on?

Thanks

I would never have flash my psp, now I can't code on it :'(
btw, do we have enough thing to start writing a psp emulator ??

hey nem you want to make you bmp to c converter program or source available?

skippy911 · Post by **skippy911** » Sat May 07, 2005 8:27 am

Well I made a little demo with scrolling text but I still cant get my gfx to show up correctly. Anyone else working on modifying nem's source that got their gfx to display??

IT say's "The GAme could not be started (80020001)"PLEASE HELP

Post by **Warren** » Sat May 07, 2005 2:03 pm

Skippy911: like I said in IRC, the pixel format must be BGR instead of RGB
cowclub: you cannot run code on PSPs with version 1.5 of the firmware installed and no there is currently no way to revert back to v1.0

Orion_ · Post by **Orion_** » Sat May 07, 2005 2:25 pm

like I said 4 post upstairs than your post skippy911

I can't understand how work the call to kernel function.
does the numbers in startup.s are the address of the functions in kernel/memory ?
how did you find them and what was their parameters ?

skippy911 · Post by **skippy911** » Sat May 07, 2005 2:46 pm

Got it working right thanks to some help with the colors:

Here is a pic for people who cant run it:
