[Release] Koens Loader Source Code

[JJS]

None of the ISO loader projects (except for the OpenIdea loader) got to what I think are the main issues:
- HBLs module loading code cannot load official game modules, for once they contain separate text and data program sections and the relocation code is not entirely suitable (especially R_MIPS_32 relocations are written all over the place)
- some official games will require modules that are not available through the exploitet game, you will want to handle that somehow

What I consider additional tasks or uncertainties:
- you will probably want to not only hook and redirect sceIoOpen and sceIoDOpen (which is easy), but probably also all sceUmdUser functions and sceNpDrm* (not sure about this though)
- you have to make sceKernelLibrary and all other utility modules dealing with atrac3 etc. available (no big problem)
- get external module loading to work

What I would not worry about at all:
- an ISO9660 reader! Who needs this if you have to decrpyt the binaries anyways. Instead of repacking it into an ISO, just dump it into a directory and be done with it.


That said I think it is a futile task because it will harm the scene by making piracy an issue again and it will just make people ***** and moan about how <insert hip game du jour> doesn't run or about how they cannot decrypt the binary without CFW.

I have to agree with JJS on this one if there is no ISO loader people ***** and complain about how they can't run their PSX/PSP games with HBL and if there is an ISO loader they'll still complain and ***** about how "so & so game" doesn't work. It's a dead end both ways and then piracy explodes and taints HBL.

If you want to play the game that badly buy the console (if needed) AND the game when you can afford it. I doubt an ISO Loader will ever be made to work on HBL unless someone with skills and who is known on PSP Scene does it, they probably won't anyway still because they're busy with other things, IMO.

I totally agree with JJS (except for the "harming the scene" part). But those are not hard tasks. And I never said ALL ISOs would work. In fact IMHO very few would work, and big games would definitely not.

if i wanted to learn psp programming

You would first have to learn programming on PC.

like making a hello world to start, and programming my own eloader

You would need quite a programming experience to write an eloader dude... You would not make an eloader after an hello world, be 100% sure about that. I don't know why people think an eloader is easy to make. Dixit Davee: "an eloader is much more difficult to make than a CFW/HEN". This is because on an eloader you have A LOT of restrictions you don't have when you got a kernel exploit. I have almost 15 years programming and it took me a lot of learning, time and effort to get to load a simple homebrew on HBL. Fortunately, very good developers joined forces on the project so it became what it is now.

when i get even more advaced an iso loader

What makes you think an ISO loader is more advanced than an eloader? They're basically the same thing: execute modules bypassing OFW protections.

is there a certain computer language i should learn, or is it all the same after its compiled?

Of course they're all the same after they're compiled. PSP only understands MIPS language machine. But I strongly recommend C/C++ since it's the language supported by the best free PSP SDK: the PSPSDK.

alright, guess i'll start with learning C++ i'm sure it'll take like 3 years for me to learn n be self sufficent though >.>, maybe i'll be on the psp2 scene lol i've looked through a C++ book, n it looks preety difficult :/

hey i remember when i asked about learning C or C++ mOskitO?? i wanted to help with issue 8 Lol UltimateKillz/mOskitO etc. Dev. showed me a link to some c/c++ tutorials guides everything that link died with advancedpsp.tk though i barely got anywhere to compiling something to say "Hello World" Lol if i find the link i post later
