I've never seen that library code, and i generally don't like "game libraries", but i can say you that S&L PSPs require nothing more than phats for homebrew to run on... only thing you have to do is make sure it compiles for 3.xx firmware..so, quoting myself:
| Quote: | Here's what i've done:
updated toolchain and sdk (now i'm using heimdall's 0.6 for win32)
placed fw_version = 390 in all makefiles
make sure all prx [messing with kernel stuff] are in kernel mode
for all prx checked exported functions
surrounded all exported functions with the k1 stuff
checked compile-time constants for hooked functions' nids
|
....then there is something you have to put in your makefiles to make extra ram available....i read it in a post from J.F., but i can't find it now... |

| Code: | | PSP_LARGE_MEMORY = 1 |
Goes in the makefile.
I think the biggest thing to change in LTE would probably be the network init code. Beyond that, there shouldn't be a lot to change. Obviously, you need to change the main header to make it a user mode app instead of kernel mode. If it tries to spawn kernel mode threads anywhere, that needs to be changed as well. I've got the source and glanced over it, but I'm too busy at the moment to try converting it myself. |

Well, he PM'd me for this, so I spent an hour to get it going. Here's the latest LTE from their site (v2.2) converted to run on the Slim.
Notes:
All examples work except for the terrain rendering demo, which hangs. Even networking works.
The gleaming gal in the demo doesn't render quite right, and the first time you shoot, it doesn't play sound. These are probably bugs in v2.2.
Although I edited all the makefiles in the examples for LARGE memory, the engine is set for a 20000 KB heap. This can be changed by changing the CAudioDriver.cpp file and recompiling the engine library. Using MAX won't give you audio since you cannot then create threads, and audio is handled via threads.
I haven't tested at3 playing. It's not part of the examples.
Bigboss and others should feel free to check out the change I made for initializing the network. The network example works great.
Everything tested on my PSP 2001-IS with 3.90 M33-3. Everything is compiled on Ubuntu 7.10 with the latest toolchain and sdk. I had to edit the engine lib makefile to change "libmad\" to "libmad/" to get it to work in linux. Also, since the toolchain uses gcc 4.1, I had to edit a bunch of the h files to correct the extra qualification errors.
The arc is so big because it's the entire directory with all object files and all examples compiled.

EDIT: here's the v2.2 edited for the slim with the heap set to 48000 KB. It also only has the libEngine and Demo compiled, so it's MUCH smaller than the post above.

EDIT #2: If you came here from the LTE page looking for LTE on the Slim, you might also check out this thread: http://forums.ps2dev.org/viewtopic.php?t=10463
That will give you pspgl on the TV, which can be used with this update of LTE. You'll see in that thread where I did a couple of the LTE samples on the TV. |

| Why does people still use this old junk LTE? I suggest using LTE Light Mod by Brick , he released it about a month ago over at psp-hacks forums under the psp-programming section , I can't post the link to the release topic because I'm on psp currently. |

Dark Chazz, still good to know this stuff (it is basics) so I'll post this anyway...
the error is right where it says 'error':
| Code: | CNetworkDriver.cpp:145: error: cannot convert 'char*' to 'SceNetApctlInfo*' for
argument '2' to 'int sceNetApctlGetInfo(int, SceNetApctlInfo*)' |
open CNetworkDriver.cpp and go to line 145 and change
| Code: | | if (sceNetApctlGetInfo(8, szMyIPAddr) == 0) |
to
| Code: | | if (sceNetApctlGetInfo(8, (SceNetApctlInfo*)szMyIPAddr) == 0) |
so it casts the char array.
The others are warnings, mainly because GCC got updated in your toolchain (from 3.x.x to 4.x.x) since this was originally created and for whatever reason this type of casting is not going to be supported, google warning: deprecated conversion from string constant to ' c8*' and you'll come across some explanations on how to fix these warnings (though often you don't need to fix warnings for the build to go through) - it amounts to either modifying the functions to take const explicity or cast things you send to those functions as const. |

Well, that's hardly LTE anymore, is it? From the linked post, he removed everything but the renderer, then altered everything in that the slowed down rendering. All it is is yet another 3D framework. There were already plenty of those out. What made LTE big was it was a full irrlicht conversion to the PSP.
If you want an updated version of LTE that compiles with gcc 4.x, try my version for the Slim, or the one with TV support. The one with TV support uses an updated PSPGL, so it can sometimes fail depending on what you're doing since LTE was written for a much older version of PSPGL. Most of the LTE demos work, but a few don't. The version that's updated for the Slim uses the old PSPGL, so it works like the original LTE, but updated for the Slim and newer CFW and toolchains.

So does anyone know what exactly makes the Terrain Demo hang?
I didn't check too deeply into it yet but it doesn't seem to throw a exception... :-/
