so we can test all combinations of few bytes (the bytes involved in the patch) until a correctly encrypted output is found This won't work, because if you change one byte, the bytes after this byte have to be changed, too, to reproduce the same unencrypted bytes as before. Assuming a 64 byte block ...

I was not so clear... I don't want to use unencrypted prx, I was thinking about patch the unencrypted and see if it works, using an emulator, then find (by brute forcing bytes) to make an "encrypted" patch to the prx. So we can have a correctly encrypted patched prx, we don't known the pri...

My idea could be totally wrong, but I want to expose it so I can get comments about it. Step 1 find a way to patch game_plugin or other involved prx to make load unencrypted eboots. This can be eventually tested using a firmware emulator. Step 2 prx are encrypted and then compressed or vice-versa? a...

I was coding a similar solution for heretic, but I was too lazy to rewrite timidity code to preload instruments, btw I've seen in your port that you are using old style mus2mid conversion over a tmp file, I've a different code that takes a memory buffer for the mus and builds a timidity midi song wi...

dunno maybe an ugly emulation ? :)

there are a python script and a c# (2.0) app to recreate flash0 structure from a psar dump (you must select README.txt in the OUT Directory), it
works with psar dumper directory structure

yes it works, it would be nice to add a switch to disable opengl at all

does psp have mmap ? then a large file can be used as read/write operation as in real memory

psp-reflashing would be usefull for a lot of things

the version in sid is a 4.0.2 with some patches from cvs of 4.0.3, it worked also with 4.0.2, but I suppose the gcc on debian has a lot of patches to avoid breaking compilation on multiple architectures (fbts) that can make toolchain work on gcc 4. You can try my builds http://forums.ps2dev.org/view...

Removed old links, new links are: Linux: http://rapidshare.de/files/8150586/pspsdk-svn-1480-linux.tar.bz2.html NetBsd: http://rapidshare.de/files/8152946/pspsdk-svn-1480-netbsd21.tar.bz2.html Note, some minor targets are not built since compilation doesn't work(I have no much time now to fix builds)

Debian sid, works fine
gcc version 4.0.3 20051111 (prerelease) (Debian 4.0.2-4)

it's a classic encryption, I've seen sony uses RSAFE or similare and there are some 2k 1k keys on the flash. I think it would be possible to generate a key pair and put the public in the psp, so the private for the community can be used to "encrypt" hb, maybe this could make 2.0 capable of...

php is not as good as python as standalone language, it's mainly used for web applications, an intresting stuff can be porting spidermonkey js engine, I've yet made a js shell with addons command for win32/unix, I may look for a psp port, I can re-use python psp module and convert it for use with js

for each char byte
check isprint(c)
if true print it else print a dot

New version for linux:

Since pspgl doesn't supports all of opengl api, sdl_ttf configure incorrectly detects opengl support but compilation fails since pspsgl misses some function. This patch solves the problem, and it will activate GL support in SDL_ttf when pspgl will implement these functions: Index: configure....

I think the wad can have some glitches, I've found on the net an utility called clean wad that should solve these kind of glitches. Please send me the save file so I can check it. Next version should have a good way to switch weapons, maybe using r/l triggers, I've not yet included that because here...

@alexmae :P @All Version 0.3 # - Version 0.3 &#58; * Added new targets ogg/vorbis/tremor/libbulletml you may need to change libTremor/autogen.sh line 30: from: &#40;libtool&#41; < /dev/null > /dev/null 2>&1 || &#123; to &#40;libtool --version&#41; < /dev/null > /dev/null ...

New versions:

Updated build script to version 0.3
http://oss.netfarm.it/psp/build_libs.sh

original autorun.sh of libTremor does this since my libtool and I think also other version returns false without params
I suggesto to change the lin to

updated the script version 0.2 changes: # - Version 0.2 &#58; * Check for gmake and fixes to work on NetBSD # &#40;and maybe also on non-GNU systems&#41; # * Removed bashism now it also works with sh # * Moved SDL & co. as last targets # * Fixed some stuff &#40;logic deps&#41...

I admin that at first sight netbsd looked to me very unfriendly, no bash no vim no wget arg... but pkgsrc helped me, it took a bit of time to compile all the needed stuff but finally I have a native pspsdk archive for you, it's made on netbsd 2.1 I don't known if it works on 2.0.2 or 2.0 (btw I pref...

svn 1280 with all libs in svn repository binaries are stripped info man doc ripped out you need glibc 2.3.5 for debian sid, you can find needed libs in .deb files (they are ar archives)

As soon as I will get installation of netbsd 2.1 in my vmware I can try to make native binaries

most of them do not build at all but I can make a script for the working projects

here are the sources: http://oss.netfarm.it/psp/heretic/pspheretic-0.2.tar.gz

I've made a bash script to build all supported libs in svn, it can be handy, feel free to add it to main svn tree without params it builds all libs specified in LIBS var inside the file, with params it build selectively the chosen libs http://oss.netfarm.it/psp/build_libs.sh It works on bash, tested...

Update, sound support added is not very smooth, but not so bad :) (I think I'll need to implement a sort of noise shaper since samples are 11khz 8bit), also a bit faster since I've enabled -O3 on the compiler (before was crashing with opt > 01 since there is an incompatible gcc optimization) http://...

I've also noticed this nightmare playing with the order of linked libraries, but I never seen this behaviour e.g. on linux, I've seen similar problems in the solaris linker, there is no way to avoid it? psp linked libs are likely to easly increase in number and this problem can be very annoying
