Looks like output.appendchar() just chucks out the given char to whatever your output is. So maybe you could replace that with putc(xx) (is that right?) or even printf("%c",xx) or anything like that. and 0xf is just that, a literal value, so c++ would accept that.
Shoule be readily convertible to c... only ugly thing is dealing with char* instead of string datatypes..
Hope this helps...!

i believe this 'deciferer' doesn't understand "& 0xf"... ie bitmasks.
he probably skipped computer class as often as the english class.

rinco, you could be right, cause this isn't working in c++. and i can't put it in java, cause i don't know anything about it, and i don't think i have the program.

ill try it again in c++ after school gets out.

out.append appends the character "char" into the output. and "& 0xf" is a binary operation to "AND with 1000".

No, the key is 16 bytes long, encoded as signed char in Java (-128..127). But please do you and us a favor and don't waste more time with another useless message. First learn the basics, like mathematic and programming in general.

i know how to program idiot. god, what the hecks your problem. ive been programming for years, a couple anyways. besides, i was only trying to help out decrypt the psp. i like to do this kind of stuff, so i thought i would give it a try. also, i knew the key was 16 bytes long, i only did the first three like i said. why do you have to be so negative, everybodies always negative. why couldn't you just say "dude, im sure you can do it, just keep trying" or something and give people a little motivation instead of saying, "your a piece of crap and can't do anything, so don't even try". oh ya, thanks zenjay, you helped me alot, i did not know what out.append did and what 0xf was. and im sorry, i did post too many times, i didn't notice you could edit your posts.

I'm sorry if I you feel offended, this was not my intention. My suggestion was meant positive: It looks like you are not able even to lookup the well documented Java class descriptions, how do you think you can do anything with undocumented, encrypted PSP firmware? And in which language did you program that you don't know computer basics, like bit operations? So if you learn more of the basics, it will be really good for you and perhaps for us, too, in some years, when you can work more professional on such topics.

hey dude, its cool, i just thought you were some jerk, i don't really get offended that easily, and im not offended at all. so thanks for apologizing. and i know a lot about c++ and visual basic and a couple other little languages, i also knew about bit operators, i just thought that java might be a little different, and i know absolutetly nothing about java, only that its a lot like c++. i thought java might have certain commands, i know you took some things out. i don't want to type a very long message so i guess ill stop here, but thanks again for apologizing, your a way different person than i thought you were. just so you know, i will admit, i was running my mouth off a little, i just thought i could give it a try cause ive done little decryption things.

we should probably get back on topic, cause i want to get an emulator on my psp or something.

/vsh/etc/index.dat is the encrypted version of /vsh/etc/version.txt

the vshell and the updater looks at index.dat to get the system version (version.txt isn't used)

sceKernelDevkitVersion returns the hex value at the end of the "system:" line (0x01000300 for 1.00, 0x01050001 for 1.50, ...)

It may return the same value but at least in FW v1.50 it's hardcoded in the PRX.

hey guys jsut wanted to mention you can access ftp through the browser by using this format:
ftp://username:password@ipaddress:port
example:
ftp://user:pass@192.0.021

could this be used to upload files to more easily I know crap about html and its limitations in psp.

sorry if this is already known, just a newb thought.
