Homebrew [WIP] 3DeSmume (DS emulator for 3DS)

[Nyap]

could you use this to install mset? just curious

It doesn't have access to the profile settings on the system yet.

Why to emulate DS when 3DS runs DS games? I don't understand...

man why to create a led ligh bulf if we aready have incandecent light bulbs ?
It's all about learning, exeperimenting and usase, maybe not be much usefull but yeah it can be XD

the most I expect here is it also being able to load carts and having a good pixeled scaling, without the "smnooth" 3DS gives :B

I have an R4 that I use with my 3DS, DS can run GBA, can I run GBA with my R4?

No. You need to use something like a Supercard DSTWO if you want to play GBA games with an R4

Nope, not without a RAM expansion pak for Slot-2.

Thank you all

So the old 3ds has a dual arm11 core and am arm9 core. The new 3ds has a quad arm11 core and an arm9 core. Is this home brew single threaded?
Graphics emulation, cpu emulation, and sound emulation can all be split into their own threads with much more practicality than trying to split the cpu emulation into multiple threads

The old3ds only has one arm11 core at 268mhz and one arm9 core at the same clock speed than a normal DSi IIRC.

Most of the time on the first core is reserved for the system, and while we can create a thread on the 3rd core (N3DS) I've never been successful at running a thread on the 4th core. And remember that the threading on the 3DS is cooperative, so only 1 thread runs at a time per cpu. The .cia of the WIP release ( one before the JIT release ) has the rasterizer running on a separate cpu, so you can compare the speed with the .3dsx and see if there is any noticeable differences.

Couldn't we circumvent the first core being reserved for the system by running a payload through A9LH?

 

[MartinDocNewland]

Well I can sadly report that New Super Mario Bros doesn't work

No, to do that we would need to write a whole new kernel for the 3ds. And the performance gain from it wouldn't be worth the effort, it would actually be much better spending time working on the linux kernel than doing something custom just for this.

 

[Roboman]

But if only one thread can run at a time then what's the point of the extra cores?

One thread per cpu (core)

It's too bad the 3ds can't have a physical ram switch, then we could play ds and 3ds games at any speed.

 

[Kirbémon]

you've come pretty far in a short amount of time, nice work!

I dunno, cuz we want to and to stop those fucking threads, i'm looking at u sirbeethoven

getting back on topic, nice to see it has dynarec supported now, hopefully 2D games are faster, haven't checked yet

I posted a list that Elyos made a few pages back, which details what works and doesn't at this time so far assuming you use the correct JIT number in the game's config. The list is still growing by the day so be sure to bookmark and keep an eye on it.

@ElyosOfTheAbyss has created a compatibility list which can be viewed here and entries submitted here.

It's understood that due to the early nature of this emulator, of course not a lot of games will work, however this is mostly for listing which games have already been tested and what the best JIT block number is.

Games listed with no JIT block number probably means that due to how broken or unplayable the game is at the time, there's no way to possibly check what the number is or that it's a fruitless venture.
