Red Dragon 3DS, Nintendo Virtual Boy Emulator Port

[hippy dave]

Arg, trying to build, but makerom tells me the elf's section size is too large, even after I've stripped it.

I just want to thank you guys very much for working on this. I wish I knew what I was doing and could help out.
I tried running that last compiled version that was posted and it just booted me back out to the home screen fyi. I was actually expecting it to freeze as it did with others.

This is going to be so awesome when it's done. Thanks again!!

Looking good so far (I assume, can't test it). Has anyone managed to get it past frame 2 in a 3dsx version?

I've been building the 3dsx versions and testing them, in fact, I'm building the latest code push and am going to test it on my XL.

Edit: I can't seem to get any .VB files to load, although it seems preliminary SD card support is being added. Is there any particular directory they're to go into, or...?

ROMs show if I put them on the SD root, but the emulator crashes trying to load them. .3dsx version just hangs, installed .cia crashes back to sysNAND.

Right now it only looks in the root of the SD. I just wanted to get the basics working for now.

What if you "git checkout 84fb862"? You have to copy vbrom.bin to /rom.vb for it to work.

Built with a copy of V Tetris as the vbrom.bin under data, and a copy of it in the SD root. Latest build fails as I said, commit 84fb862 crashes before reaching the menu.

I'm using commit 84c85711f8 and I have "rom.vb" on the root of the SD card (Seems to work now). It works properly, however, selecting the rom crashes the application and boots me back to the system menu.

Methinks it has an issue with allocating memory or something upon launch of the VB rom.

Well, I'm stuck. I'll look into it when I have time.
The good news is that I might be getting a copy of CN after being told by the Amazon seller that they didn't have any stock.
The bad news is that I have exams coming up and I won't be having a lot of free time until Christmas or so.

Sorry to necro this, but was curious if there's been any progress made? This project is something I've been hoping for since the 3ds first arrived.

It has been updated a couple of times last month at github. Last update is 10 days ago....

I've been posting the progress here: https://github.com/mrdanielps/r3Ddragon/wiki/Current-progress

Basically, I've fixed the problem with ninjhax and a few bugs, worked on rewriting the interpreter core in assembly, realised it wasn't giving a big performance boost and my 3DS broke.
After taking it to repair I started working on the dynamic recompiler and two weeks ago they told me they couldn't fix it.

I'm still working on it but I'm a little bit busy with other stuff right now. If anyone wants to take a look at it there's a "dynarec" branch on github, although I wouldn't advise anyone to use it unless they want to contribute. Only a few homebrew demos work properly, it has huge memory leaks (there's no proper cleanup because I'm lazy) and it's not that fast (a 2X improvement in the best case) because I'm focusing on getting things translated properly before optimizing it.

I'll make a proper release thread once I think it deserves one.

Also, I've got a N3DS now.

Has someone compiled the latest build and see how well it performs?

Here's a quick comparison between the interpreter and the dynarec (based on the ROM you can see here: ):
Spash screen: 3.7 -> 7.8 fps
Controller test: 5.9 -> 7.75 fps

It's not a huge difference but the current code is much more optimizable, so I'm pretty sure it will be better in the next few months.

danielps, thanks for the video!
Good thing is that there is still being worked on at a normal pace, but it will be very fruitful at the end.

Just to clarify, that video was recorded by HtheB back in November.

Has there been any progress with this Emulator? Would love to have this on my N3DS

Progress has been slow because I'm busy with class.

The dynarec is doing well. In fact, I fixed a few crashes and graphical glitches yesterday.
Most ROMs won't work yet and debugging can be a pain. I'l probably make a compatibility list on the github wiki later next week (there's one already for the interpreter).
I'm focusing on getting flappy cheep-cheep working in-game for now and it's getting close. It gets to the menu screen but crashes when starting on real hardware.
However, on 3dmoo it works perfectly, except that pipes change position every frame, which would make it extremely hardcore I guess...

It's nowhere near full speed yet but the fps values I posted the other day should actually be doubled because timing is broken and display interrupts aren't triggered at the right time.
Software rendering is really slow too, so that's another thing I need to fix before releasing something decent.

Awesome. I swear Wario Land is going to be great on the 3DS
