Comment out that line in build.py ( ex. #upload("Launcher.dat") )

done it now it shows up

Interesting stuff, I may try messing around with this. Not running anyone else's code tho, unless I have a way to unbrick.

 

[gamesquest1]

Yeah the whole bricking fiasco has kinda made me a bit paranoid in terms of homebrew, no offence to the coders, I don't actually think this is advanced enough yet for doing the level of damage the brick code does.....but you can't be too careful

 

[TheCruel]

Anyway, try it at your own risk. I don't take any resposability.

OMG fffffff, my 3DS exploded!



Well, my compiler exploded since it seems you probably didn't update the git repo with your latest files.

For instance: https://github.com/nop90/3DS_Homebrew/blob/master/HID.h

ifndef HID_H
#define MEMORY_H

Looks like a quick copy & paste from memory.h lol and forgot the #

Also, you changed the names of some of your constants:

src/draw.c:59:10: error: 'BOTTOM_FRAME0' undeclared

Thanks a lot though, I'm toying with it right now. But I'm also struggling to figure other things out. Where did you get the addresses for your framebuffers? I'm looking at the 3dsbrew.org documentation and I'm not seeing some of these things.

I think some more 3dsBrew links should be in the main page as we learn more about what information is useful.

 

[TheCruel]

Yeah, but what I meant was that the information wasn't anywhere on 3dsbrew. His addresses are different than the ones documented. He has these address:

#define TOP_LEFT_FRAME1 0x20184E60
#define TOP_LEFT_FRAME2 0x201CB370
#define TOP_RIGHT_FRAME1 0x20282160 
#define TOP_RIGHT_FRAME2 0x202C8670
#define BOTTOM_FRAME1 0x202118E0
#define BOTTOM_FRAME2 539039968

Is there a base address that is offsetting these or something?

#define TOP_LEFT_FRAME1 0x20184E60
#define TOP_LEFT_FRAME2 0x201CB370
#define TOP_RIGHT_FRAME1 0x20282160
#define TOP_RIGHT_FRAME2 0x202C8670
#define BOTTOM_FRAME1 0x202118E0
#define BOTTOM_FRAME2 539039968

Is there a base address that is offsetting these or something?

From the "Python Tools for 3DS" thread.

0x5d, 0x87, 0x8d, 0x59, 0x83, 0x88

search this patten from 0x20000000, you will find the framebuffer for bottom screen.

(I think what 3dbrew shows is the registers that give the addresses not the addresses themselves. Those addresses are correct though except the last one)

Sort of unrelated to your question but noteworthy:
There is a bug in the paint_pixel function that is causing it to draw 3 bytes past the addresses.

as it is:
int coord = 720 * x + 720 - (y * 3);
as it should be:
int coord = 720 * x + 720 - (3*y+3);

Also the BOTTOM_FRAME1 frame address is the same as BOTTOM_FRAME2 address.
BOTTOM_FRAME2 should read:
0x20249CF0

 

[tomiga]

I uploaded on github a small update with:
- Buttons management
- Fixed pointers for all six buffers

No buffer swapping at the moment, but now the program draws to both framebuffer to avoid blank screens if the second buffer is active.

I attached the executable for people who are not able to compile the sources. You should not execute it (I would not!) because it's very easy for a bad guy to brick your 3DS, how GW did.

Obviusly I'm not a bad guy :-) , but every bad guy would say this :-/

Anyway, try it at your own risk. I don't take any resposability.

nop90

Nice job nop90, works perfectly on my 3DS (after formatting it twice because the ROP loader is bugged...). Also shows some nice starting points for 3D rendering.

How are you finding the addresses?

 

[Snailface]

From other people smarter than me.

I figured the BOTTOM_FRAME2 address by just adding (240*320*3 bytes)+16 to the previous framebuffer. Same pattern as the others. Then I test them to make sure no grey dots on the corners or wrong overall colors, both of which signify an incorrect framebuffer address.

 

[nop90]

Some of the file on github wasn't updated. Sorry, I uploaded them at late night (in Italy) after a hard working day.

Now they are ok (I compiled them and checked on the 3DS).

 

[T3GZdev]

so which github has the best version for a standard one? or newest. i seen snailface, insancekane, nop90, aliak11 & i think a few others. currently using snailface's latest one.

I think nop90's version is the best tbo -- its very extensive and even has controller support. You might want to take his source's and combine them with my latest build environment (haven't updated my github yet):

I would completely erase all my source files before putting his in or there will certainly be redefinition errors. leave bootloader.s though.

i tried that. im using your download from here.

None is better or standard at the moment. I'm studing the GPU and as soon as I'll learn how to make GPU command calls, I'll change all the drawing functions.

Not to say that I used other people code and made some change.Other people will do the same with mine. Slowly ther will be something like the libnds for writing standard code without thinking at the low level things.

I like playing with low level programming, that's why I'm expering with 3ds and not coding on DS or Android.
