Modding Attempt


Is there a way we can decrypt these sprx files in IDA and read it's code from the way it was written or is it all have to be read in PPC?

NOW THE FUN PART! .BSP FILES!!
For those who are active with source games you know that most source game maps run a file format known as "BSP" from my understanding with the ps3 versions of these files is that they are heavily more encrypted than the pc version and viewing or editing these files for ps3 requires c++ magic.. BUT!!! there was recent documentation done by people on the "ORANGE BOX" game which has all 5 popular source games. The following video shows that a person has engineered the xbox version of TF2 to run custom maps but he said it's a tedious process... here's the video and forum link

Overall I'm in dire need of understanding sprx files and i want to mod a game that hasn't modded on console before for awhile. So feel free to chip in! Just make sure you have a copy of protal 2

all the sprx r ppc lol and when they load each one into memory it can have different addresses as to where its load therefore u would have to search each function or ppc edit u are doing within the sprx or u can use a sprx and the function sys_prx_get_module_info to get the sprx location (you can also do this with TMAPI if you don't wanna do sprx stuff but then u won't get far with modding this game) and then have to get the toc address etc, there bit of stuff you would have to do to i suppose in other words fully made a mod menu or cheats seeing you are asking this without knowing how to make it all work out right for you, but good luck to ya, i would read over the ps3 sdk aswell as the source sdk and u can do dank haxs on source engine games but this game is old so don't message me about anything for this game :p

edit

if i recall there is a cfg file u can do simple bind mods like godmode ufo etc

Are you asking for help for Portal 2 Modding, or are you just stating you're attempting to mod it? Smile

cause i didn't know much as i do now back then and the addresses change each time a sprx loads into memory therefore it didn't work unless i did a address finder :p

it would be very simple to do it again, the game uses source engine the same engine based off cod, if u search for the string cbuf_addtext in one of the sprx files u will find the function and can execute any console commands lol

And with that would come the ufo command Gasp Always wondered how the outside world looked like, and whether it's able to be walked around on.
