Thanks to everyone on Freenode's #pspdev who put up with my questions.

Glad I could help urchin!

Now if I could only get motivated to do some VU coding instead of waiting for a PSP 1.5 Homebrew loader. :-\

Here's the URL for the 1.52 (Jap) firmware update:

Heres some info about the ARM9 processor in the PSP and JTAG goodness. It is most likely futile to attack the ARM9 for weaknesses but maybe someone will think of something.

alonetrio: Sorry to see you busted your screen. Same thing happened to me... I had to return mine to Bestbuy... Thankfully they took it back, but they had no others to give me :-( If you are slightly "mod" inclined there is an interesting site that is offering a used LCD screen for $150 US...

KiWi: IC9001 does not look like a good canidate to me. MIPS uses an interface called EJTAG... Which has a pin arrangement like this * * * * * * * * * * * * * I found this at http://www.mips.com/content/Documentation/MIPSDocumentation/EJTAG/MD00047-2B-EJTAG-SPC-02.62.pdf?agree=yes You just need to cr...

Hi everyone, I tried joining #ps2dev today on EFNET Webchat http://chat.efnet.info/irc.cgi I get *** #ps2dev Cannot join channel (+b) I've never been banned before! Did I miss something? ...is wechat not playing nicely? I feel left out :-( I guess I'll try again when I get home from work and can jum...

nice job pdc!

the scene seems to be opening up very rapidly :-)

let me know if I can help... i don't have a psp yet; but will be getting one as soon as best buy carries them.

sorry blackdroid...

i was not taught the finer points of the GPL license in college... i have read about two paragraphs and do not wish to read anymore :)

the post was mostly meant to be a joke, as i don't think u will be able to reach anyone directly calling that number.

sorry sony ;-)

so the psp games that sony releases are just signed/encrypted? no stopping someone from loading a bin file from the memory card! interesting... so maybe there is a buffer over/underflow in the file decryption code.

This was on slashdot recently: http://developers.slashdot.org/developers/05/03/18/0315241.shtml?tid=117&tid=156&tid=17 Seems that maybe we should give Sony a call: http://www.yellowpages.com/SearchResult.aspx?page=home&searchform=homesearch&typeorname=name&search=Sony&searchf...

Flint: If they were smart they would have disabled it in the hardware... but this would have required them to produce a modified version of the dev chip that handles code execution on the mem card. This modified chip... could be as simple as removing a trace/pin on the chip, would then have to be ma...

ooPo: sounds like a great addition to me. this might be bringing the subject matter a bit off topic but i think anyone jumping into 3D code without understanding the math first is in for an uphill battle... if anyone out there is looking for a primer: http://www.flipcode.com/articles/index.shtml i'd...

hi all, ok... new link at my site... should make it easier to find stuff now. http://staff.philau.edu/barberej/ps2dev/ i should be compiling the demo harness from cvs in the next day or two, the vuharness.elf that i recieved on IRC seems to be giving me display problems... i'm hoping the cvs version...

mharris: thanks for the clarification... i just noticed eratosthenes had mentioned this too :-\ We have to write down numbers the opposite way to how we usually think about them. We usually write the most significant digit first, in this case starting with 127 and counting down, but we usually think...

since the EE is little endian

I thought MIPS was usually big-endian? I have heard that it can be little endian too though... is the EE a "special" MIPS processor?

mharris: Thanks for going over why I needed to use dvp-objcopy. It makes a lot more sense to me now. Also thanks for the tip about hexdump... I just assumed a hexdump was a hexdump. :-) Sorry for not posting this sooner... for some reason I didn't see your post last night, prob since it was within 5...

Hurray!! Thanks carlosn! Everything worked this time... just required your magical compilation steps ;-) Final source for those who want to follow along with the tutorial. This is just Example 1... more to follow. http://staff.philau.edu/barberej/stuff/eratosthenes_ex1.tar.gz Link not valid anymore....

Well it didn't seem to work :-( At first I just tried reversing the Qwords as carlosn suggested: In your program ggp.c the qwords in your gspacket are backwards. GIFtag_a32 -> GIFtag_d32 GIFtag_b32 -> GIFtag_c32 GIFtag_c32 -> GIFtag_b32 GIFtag_d32 -> GIFtag_a32 Swap the words for the rest of qwords ...

Shazz

Thanks for the pointers.

Tonight should be fun to see how this whole vector unit thing works.

See you on IRC!

carlosn: thank you! i remember reading that you have to watch your order on MIPS architecture, i guess i should have taken that section of the tutorial a little more seriously. when i get home from work today i will give it a shot... Saotome: looks like a nice set of basic calls for the VUs... i wil...

Hi mharris, Thanks for the reply! I'm using adresd's VU harness so I havn't thought about creating any c code to load the data into the VU.... i just run: ps2client -h [ip] execee host:VUharness.elf I put my demo.bin, demo.dat, and demo.hlp in /bin/bin/demodata I also changed...

Hi all, I have attempted to create the first demo on Eratosthenes site: http://paulsmith.is-a-geek.net/vututs/ Mirror: http://www.pcs.uklinux.net/id19.htm Here is the code that I have put together: http://staff.philau.edu/barberej/stuff/modman_demo.tar.gz Link not valid anymore... see later posts I'...

Wow, really cool!

Any progress? It runs < 30 seconds on my PS2... I'm guessing this was just a proof of concept.

Well my Action Replay Max Evo came today!! Just in time for a great snow storm :-)

Does anyone know how to transfer the max file from ps2xme to the USB dongle in linux?

Thank you for the good overview DracoLacertae and gorim! I did not recall load delay slots from my class... must have been dreaming of getting my PS2 back then :-) I found a good explaination of delay slots on MIPS here: http://www.go-ecs.com/mips/miptek1.htm So does the instruction in the delay slo...

Anyone use this before? I'm trying to get myself back into "assembly mode", and was just wondering if this would be usefull: http://www.cs.wisc.edu/~larus/spim.html ?? It says that the new version supports the MIPS32 architecture. I used this before in my Computer Organization class; but I...

Thinking about it some more I realized that if I wanted to stay up to date, or help ps2link stay up to date i should just go out and buy the X-Port. http://www.pricegrabber.com/search.php?topcat_search=1&form_keyword=X-Port&topcat_id=&Search=Search Time to wipe off some of those old asse...

i don't want to alter any hardware. just looking for a reliable coding project.
