Homebrew Homebrew Development

I though that since this thread: http://gbatemp.net/threads/how-to-assembling-3ds-homebrew-for-gateway.365885/ we might be able to play NOP90's tetris 3DS HB, and im sure I saw a nes emulator possibly? ah well... back to kirby triple deluxe...

The play coin generator is a sdk app.
The multicolour screen app is nowhere avaible as app I think.

So, even now the play coin generator doesn't work? Or you're just saying it's not technically homebrew?

yeah it does work you need to get the one repackaged by 3dsguy though.....i think he was just being finicky as it was a debug tool as opposed to homebrew

also i don't remember where i got the gradient screen homebrew, but it is on here somewhere......doesnt do anything except having a coloured screen with occasional flashing....but that was is homebrew afaik, if i remember correctly it was from a tool made for creating your own homebrew game icons, but i cant seem to find the thread no more

He's just saying that it isn't technically homebrew. The generator works just fine.

Edit: ninja'ed

Sounds a lot like this, though the flashing is an unintentional side effect in that one.

How coders found the address of frame etc ?
They are not in 3dsbrew .

But then how do games allocate the amount of memory they need?

this is my guess how it works. the 3ds has 128MB ram. the some is reserved to the system menu. im not sure how much. maybe 32M. the rest is used for games. when a game is ram the system says ok here is your 96MB, enjoy. the game cant see the 32mb section used by system. when the software is closed, system wipes clean the 96MB for use with another software.


so if a ram dumper was made all it beable to dump is the empty 96mb ram it was given to use

hmmm but if i remember correctly, the launcher.dat ram dumper was able to dump some game assets, so im not sure the ram is cleared upon closing the game, although it might be possible that it would be wiped upon launching another game, but who knows it would still only be scraps of what was left loaded into memory might be useful for audio rips and stuff like that. i assume gateway loads itself into the system settings side of ram which would not be accessible by a app running in usermode

games take half the fcram and use that. each program manages its own memory internally via one of the sdk allocation systems or something custom.

I ripped some sound effects from a couple games using the launcher.dat ram dumper, but not anything more than 10 seconds or so

I tried loading the homebrew screen test and got a blue screen like the one that bricked consoles show...Is this normal? I thought my 3DS was bricked until I tried rebooting and it seems to be working fine. Also is there a way to convert Homebrew launched via a launcher.dat to a gateway compatible format like .3ds?

Yes, that was exactly what was meant to happen, it's like a fake bluescreen app. A fun prank while seeing about getting things working properly.

Yes, but you have to compile it yourself from source. Tools will come out shortly to get homebrew running proper, right now it's more of a developers only thing.

Ah...now I feel like an idiot Do you think it be possible to write a program that runs in the background and takes screenshots of running games? It would be really cool if we could eventually record game footage! I have a friend with an xbox 360 development kit and it's possible to record game footage without a capture card.

I can't answer that, but perhaps someone smarter than I can. Maybe flashcarts at some point could develop a menu similiar to the DSTwo that has a screenshot function, but idk if an external homebrew app could do it.

With the current Gateway Homebrew setup it wouldn't be possible. You wouldn't be able to spawn a background process and have it continue to run while you switch to an actual game.

I guess it would have to work like PSP plugins.
loaded by the loader (here gateway's Launcher.dat) to patch the System menu and add new features.
You will have to understand how the system menu is working to patch it.

 

[Vappy]

Which I thought would be impossible with the GW loader because it doesn't enable enough control to patch the system menu?

i think he means gateway would have to allow such a feature, either letting people make plugins which gateway will then load......pretty unlikely, or they code it themselves and include it in a update....but i think they have bigger fish to fry atm

that or someone hacks the launcher to add patches in that gateway doesn't normally allow, but seeing as the devs who could do such work probably realize it would end up as a rom loader pretty soon after so would have no interest in doing so, or work for a rival card team and are busy copying the code to add to their card, that option seems pretty unlikely too, only real option would be asking gateway to include the feature and they might add it in if they think its worth the effort

one final option would be seeing if smealum would add a screenshot feature or something into his work, but seeing as he appears to of dropped his focus from the 4.5 exploit in favor of ssspwn i dont think that would be an option either

i might be wrong, but I'm fairly sure he already did this ages ago...

He might have "done" it but he hasn't shared the method for doing so IIRC. Most of the non-homebrew related hacking stuff he simply just shown it off, I am not aware of anyone else replicating what he's done. Using the scientific method, since his results had not been replicated by anyone, we cannot take it to be the absolute truth. It's a pity, things like unlimited 3DS hacking and cold fusion is just a pipe dream.
