ship only to us ? :/

you find all this by reversing the bios code ? o_O
amazing.

you don't understand that 1.5 run only Encrypted program !?!
you must encrypt the elf, else it will not work ...

thanks a lot to beefyoxo for beta testing my little demo
after some test, here is the final version with correct colors :)

no, even if we have a dumped 1.0 bios, the 1.5 update program contain an encrypted bios, so we should encrypt the 1.0 bios to replace the 1.5 one, and we still don't know how to do that, and if someone find how to encrypt things for psp, then we don't need 1.0 bios anymore because we could encrypt t...

looking at the video, the effect is very slow, and it should be faster than that ! (I use fixed point precalc table)
I guess the cpu don't run at fullspeed. if you want a good emulator, we must found how to overclock the psp to its max speed ^^

nope, I use BGR :)

here is the video, thanks to beefyoxo

anyway, the colors are all wrong, even with a correct version, I can't understand why :(

thanks for the pictures !
unfortunatly , the colors are all wrong :(

I would be glad if someone could make a screencapture, It should be like this (this is the pc version)


beefyoxo : I can host it :)

pokeman1019 > thanks !
what does it show ?
I hope the graphics and colors are right.

-_-'

mmh, seems that all posts of the page 4 are gone/deleted o_O

I tried to do something fast but can't test on my psp, cos I flashed it to 1.5 :'(
could someone with a 1.0 psp test it ? thanks :)

thanks for the answer :)
my utmost respect !

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 ?

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 ??

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

yeah! psp have direct framebuffer access, it rox !

maybe you could use the libhttp prx file from wipeout umd.

disassembler anywhere ?

maybe but I can't see the library name in the elf file :/
thats why I say that

I'm not expert in Elf file format but it seems not to call any system function, so this use pure hardware hack ? O_O

:/

great work nem :)
would it be possible to have some technical info about how you did this hello world ?
how did you find how to init hardware, and show something on the screen ?

I think, using the umd drive of the psp would be easier, but we need a hardware hacker ^^

I read a post about this somewhere, so yes, someone has already done this test.
it was with ridge racer and the japanese rpg game I think, can't remmember the name

nahhh don't lock, I want to try something, and I don't want to create a new topic =)

what about the xlink error then ?
after that none of the button is active so I can't send elf file, it's say "offline" :/

I know but how to make it on the memory card, I mean, I don't know why it need to search anything on memcard, why putting a ps2link iso file that don't work, there is nothing about file on memory card explain in the readme of both program, I also tried ps2exec, and inlink, it doesn't work ... is the...
