Is there something in this that would prevent it from working with the corruped image remover, or Sei's PSP tool? I've tried the corrupted image remover on the KXploit version in the download, and it breaks the program. Sei's tool complains that the PBP is not valid to write. I've tried Sei's tool o...

The problem is also that someone on Sony's line could very well have said that the PS2 has USB 2.0 ports, because it does. USB 2.0 full speed. full speed == USB 1.1. high speed == 480mbps. I'd assinate the USB Forum if I ever had the opportunity. This has made buying computer components so much more...

Either baudrate is not in bps, or brd allows values less than 256.

256=cpu/(baudrate*256) gives an answer of 4500.

I also noticed that baudrate * 256 yields 115200... :)

An LCD is made up of three layers (or more if using different colorspaces) of electrically responsive grids of optical filters. Basically, a pixel is "green", because the red and blue filters are active, only allowing green light to pass through. An LCD can suffer a kind of burn-in where t...

The nature of encryption is such that a change of even a single bit in the pre-encrypted data will likely end up with every byte being different in the encrypted data. I was thinking with the PSP doing real-time decryption, that the files might be broken up into smaller sections for the purpose of ...

would the swap trick work on a 1.0 psp?

theoretically it might ( although there is absolutely no reason to do it :)

The way software development works, odds are if the swaploit is in 1.5 it's in 1.0 also.

Ugh x2. A diff would still be useful since we would be able to guestimate how much of a change there was between the versions of each of the files. Maybe we'll get lucky and most of the files have very very small changes. :)

I haven't fooled around with an exploited PSP, so excuse me if this is beyond the capabilities we have today... Instead of just comparing the files, can you run a diff on them? I imagine you'd probably have to copy the contents of flash0 onto a MS or something to that effect - I do not know if this ...

Strange that you're quick to single me out as a zealot against your apparently favorite language. I wasn't trying to single you out, nor is Java my favorite language. That said, it is useful, relatively fast and Sun seems intent on it running on every processor and OS under the sun (no pun intended...

If I wanted to do java development on a portable device, I'd buy a cellphone. However, I'd appreciate it if you'd stay on topic and not post your personal wishlist in the middle of an ongoing conversation. So are you one of those people who think that Java is too slow compared to C/C++? Sorry about...

well, so far SONY has provided homebrew environments for all consoles they released (for PSOne you had the Yaroze and for PS2 you have PS2 Linux) about 2 years into the consoles lifecycle ... let's see what the future brings and never give up hope. just give it some time young padawan! ;-) If Sony ...

Yes your idea of finding opcode patterns is stupid, I suggest reading a good book on cryptography to understand why and when the idea of finding patterns in cryptographed streams was abandoned. And as gorim said we are able to run code on the PS2 without having the key. And as I said, the only way ...

Besides, do not think for one moment there won't be a severe reaction from Sony if we are able to decrypt intellectual property meant to remain unseen. Not that Sony needs to worry that much, of course. But there might be some lines we need to define so that we don't cross them, and that can be har...

In my other thread (which was locked... I don't think it's useless since PS2DIS doesn't currently decode PSP files because they're encrpted or compressed, but whatever) I decoded some of the R4000 opcodes into hex and binary. As near as I could tell, there was only one that took no arguments: sync. ...

If someone can make this hack read out the contents of the memory @ address 0, we might be able to start disassembling forward...

Dunno, I may be the only person that uses this, but it comes in handy for searching through binaries with hex editors like XVI32... Conventions: X means variable. + means or. (0+8) means 0 or 8, X000 in binary. - means through. (0-3) means 0+1+2+3, 00XX in binary. R4000 ASM OPCODES (hex&...

Has anyone looked to see if the code in either of the unknown files correlates to normal MIPS ASM?

If someone can post or e-mail to me the files, I'll look up the opcodes and compare them myself (if no one else has).

484*172*32 = 2.5MB. If we assume that the framebuffer is a part of the main memory map, we can also assume that it's large enough to justify having a whole dedicated section of the memory map to itself. My suggestion, to find the address it starts at, would be to write a program that at every 1000h ...
