HTMLViewer in Homebrew

[Ooblik]

I cannot for the life of me figure out how to load the internet browser in my program. I have gone over the htmlviewer sample in the SDK samples and i tried a few different ways to add it to my code but then i try to load the browser it just crashes. My code compiles fine so i have no idea what i did wrong.

If anyone has figured this out already help would be much appreciated :)

My Code:

browser.c

Hi Ooblik, welcome to the forums.

What heap size are you giving your program?

[Ooblik]

PSP_HEAP_SIZE_MAX();

I also tested it on a Slim with PSP_LARGE_MEMORY = 1 in the Makefile to see if that would make any difference. Still just crashes...

[J.F.]

Probably BECAUSE of max... try not allocating all the memory to the heap.

[Ooblik]

Still crashes when I set it lower.. hmm.. I think it might be something graphics related..

[J.F.]

You have the browser set to allocate 10 MB of memory... did you leave at least that much free? Lowering the memory heap from MAX to MAX-1MB won't allow the browser to allocate 10 MB. :)

[Insert_witty_name]

You need the 10MB for the VPL and you need around ~6MB of space free for the cache too.

PSP_HEAP_SIZE_MAX() is no good.

You can get away with allocating about 3MB for the VPL, but you still need 6MB of space free for the cache.

[Ooblik]

I've already said i tried setting the heap lower. So are you saying its not possible or what? If it is what should the heap be set too?

[Insert_witty_name]

Give the VPL 4MB.

Set your heap size to 8MB.

Experiment, it's hard to say otherwise.

[Ooblik]

If i use

Code: Select all

PSP_HEAP_SIZE_KB(-12*1024);

then the browser doesn't crash but it says:

Code: Select all

Error 0x800200D9 initing browser.

* 800200D9 = failed to allocate the memory block

I load a bunch of images and the main fonts with IntraFont before this.

[DylanNIRVANA]

Sorry for bump.

Ooblik the error you refer to:

0x800200D9 = failed to allocate the memory block

check over code?

[Art]

Audio Mechanica uses almost all the RAM, so I used the eboot launch sample
to launch a seperate browser eboot from the program menu,
and then when the broser is done, it relaunches the original eboot into the
menu, so it looks like the web browser is built in.

[Ooblik]

Thats what I ended up doing. The browser is really slow this way though.

[J.F.]

Thats what I ended up doing. The browser is really slow this way though.

The browser is really slow ANY way you run it. :D

[Torch]

You could load PSPKVM (and maybe modify it to disable its main menu, and to exit back to your eboot) and set it set to autorun Opera Mini. At least the browser would be fast.

[Ooblik]

I mean that it becomes laggy, not the download speed..etc.

[MysticWhiteDragon]

I'm not sure if you are willing to do this but you could always port a browser or make your own. Here are two good sources if you are willing to take this approach.
