If I may say so.... libc and it's implementations (namely newlib) are all so clobbered with function redirections and functionname dissembling that it's just a freaking PITA to work with it or do any changes/fixes.... who the hell decided that the code must be so unreadable that only the ones that w...

Well, though your idea is nice, it won't work out. The problem is that the additively blended scene would change the color effects of the output image in a non-realistic way. You really need alpha blending for it to work. You could achieve that by using DST*SRC blend and DST*(1-SRC), then adding tho...

The full list of ops and their explanatory C code counterpart is in the first of the threads I listed. It's the most complete documentation available

No it won't. Anyway, it will just crash at some point as it is constantly leaking memory.

I'd guess writing to ME memory while the video/music plugin is running or a game is using ME's audio/video decoding would be a problem though, no?
Which games use the volatile memory?

Did you try the module in vsh? I assume most exported NIDs for impose_driver work only w/vshmain running. Yes, that's where I tried it first, but it doesn't load neither in VSH nor in game nor from PSPLink. Maybe you should try to build other impose library, and using 00010011 as flags. Funnily eno...

PSPLink tells me 0x80020139 when loading the prx, which resolves to "exclusiveload" - whatever that means. When I try to load the .elf directly, it says SCE_KERNEL_ERROR_MEMBLOCK_ALLOC_FAILED (0x800200D9) - though that's probably because it's not inside a prx. I'm on 3.52-M33 so the NIDs s...

Just tried it and I was sure that would be it, because I just didn't think of that simple thing. But unfortunately, that didn't help :/ Thanks anyway

I have a kernel mode prx plugin for custom firmwares, it works perfectly fine but as soon as I add a sceImposeGetParam(PSP_IMPOSE_MUTE) call the plugin fails loading. I first assumed it was due to the import stub being wrong and linking the user mode version of the function, but that wasn't the case...

I just had a peek through sceImpose again (for some other reason) and hit the sceImposeGetHomePopup function once more. Isn't that function returning the current state of the Home button popup (off/on)? If so, that would be the solution to the problem. Not sure if that function is available in user ...

I think it should, although I tested Pinball and found out you're right. Otherwise there's no reason for a "Yes <> No" requester, so there's a bit of an inconsistency. If it's not going to pause, I think all games should just exit without the request. Well, the HOME button shouldn't be co...

Raphael : I would agree with you if there was not the confirmation screen. So if one presses the HOME button, okay the program exits, that is what the user wants. But the user can confirm his choice, so during the time he's taking a decision, I find it unfair that the game continues to evolve. I do...

@param setup - Setup the screen if 1
Well, that tells you it sets up the screen if you set it to 1. That should already be enough information for usage. If you're interested in knowing exactly what it does, a peek into the pspsdk source reveals everything (src/debug/scr_printf.c).

The question is, why do you want the game to pause when the user presses the HOME button? The HOME button isn't intended as a "PAUSE", so the user should only press it if he really is about to exit the game. Actually, I've yet to find a commercial game that pauses gameplay while the home b...

Don't know about the second function, but silverspring.lan.st says: 0x6D945509 sceCodecNotifyAvcKick That nid isn't right. The function definitely sets the LOUT1 and ROUT1 volume registers in the codec. It looks like the outputs are enabled and disabled in sceCodecOutputEnable. The prototype appear...

The wm8973 datasheet is a good place to look for info. It looks like the speaker (fat psp) is connected to the L/ROUT2 pins of the codec and the headphone is connected to L/ROUT1. By that nid 6D945509 is sceCodecSetHeadphoneVolume and nid 40D5C897 is sceCodecSetSpeakerVolume. Don't know about the s...

In that case: If you blow your PSP, it will eventually 'blow up'.

using the cord that i have (one side mini b the other usb-female) is it possible of coding SOMETHING that could initialize it so that it'll work with the PSP? {instead of, or together with the current OSK). i really think it'll help programs like dos box and others which need a keyboard. also you c...

Well, you can just see.... The audiorouting setmode function just sets a 0x20 event flag in sub_00000000 and passes some params. This would not be suspicious if the HPRM connect handler in impose.prx didn't do the same ;) So I think something is wrong in the way it is called - maybe it doesn't like...

Thanks, somehow I missed that thread when searching. Seems that adrahil failed when trying to provide a software solution and chopping off the Tip of the phone jack is the easy hardware solution. That could work out, though I'd have preferred a software solution (gonna ask adrahil when I see him). ...

It seems that version 0.2 doesn't work with new firmware 3.80.

I get "The game could not be started (80020148)" when I try to run it.

Any help will be appreciated.

Thanks

This is worthy for hall of shame :/

Well, makes sense then to do it that way :) thanks

Isn't the cache 16kb? I believe the entire cache (i+d) is 16kb, but i'm not 100% sure. Both CPUs contain 16KiB of two-way set associative instruction cache and data cache respectively. Though not the best source of information, I understand that as 16kb for each. Someone reversed the sony function ...

Thinking about the threads I've read on the PSP cache, it seems that most cache commands are run twice, supposedly because the MIPS cache is two-way set associative, meaning you have to do the command twice to affect both sets. That shouldn't be the case as 0x14 is index writeback invalidate and th...

deniska: As I see it, the code in mapthis works by overriding the interrupt handler *before* something is plugged into the jack, hence speaker sound output isn't overridden, correct? Well, the problem in my case is, that I cannot just override the interrupt handler as I need to stay compatible with ...

Because it also uses the 2.6 kernel i think.

Would be cool, playing some games etc etc (i suppose music wont work).

iPod is ARM, while PSP is MIPS.

Just for notification: I added pspvideocodec and pspmpegbase to the SDK.
Still needs some documentation on the use of the "Video_Codec_BufferMP4V" (best create a matching struct) and Video_YCrCbCopy_Buffer (already created a struct for that - see pspmpegbase.h).

pspGL isn't really complete, it provides most of the basic functionality, but if you need anything advanced you'll probably soon hit the roof and need to go the direct anyway (one thing I remember being QUAD rendering not supported - not sure if that has already been fixed or not). If you have knowl...
