Out of curiosity is it still possible to play 4MB WonderSwanColor titles via the DS Lite, or does this only work on DSi and 3DS ?

(I tested Rockman.EXE WS but file is too large for my DS Lite)


Awesome emulator bdw, I'm super amazed and had loads of fun playing Mr. Driller on ds. ^ ^
On NDS/DS Lite you need a SLOT-2 RAM cart for games that are larger than 2MB.

This is probably one of the last releases for this emulator in a while, need to do something else for a bit.
The cpu emulation should be the most accurate of any WonderSwan emulator, will release my CPU test publicly soon.
The source is available for anyone to tweak and add stuff, I'm open to pull requests.
  • Added alternate joypad layout.
  • Fixed unsigned mul on ASWAN.
  • Fixed immediate mul.
  • Fixed 32/16 division.
  • Fixed IO register differences between mono/color mode.
  • Optimized 16-bit signed mul.

Thank you for adding the alternate joypad layout. Although the layout was a little different from what I had written, I was able to play Kerorikan without any problems.

Another problem is that the sprite appears in front of the text. I noticed this while playing Romancing Saga. You can read the text by turning on Disable Sprites, but it's a hassle.

I'm using the emulator on an R4 in my 3DS and i'm getting the file too large error when trying to launch makai toushi saga, is there something i should have done? I extracted the emulator and game and just dragged both into my R4's main directory

An R4 will not work with that game. You'll need to install TWiLight Menu++ onto the console's SD card in order to play the game.

I try scminisd as slot2 ram,it doesn't support it ,but support ezflash4.
But TWiLightMenu supports scminisd card as native gba ram better than ezflash4,
Can mix them together?

Is there any comprehensive comparison between this and dualSwan? Better power, better compatibility etc?

I always get worried that I have missed something. Are there games that are not working correctly that are not in the readme file?

Eh I only play the games I can play in English, including those with translation patches and maybe fighting games, and so far they seem okay? I haven't beaten any of the RPGs I can play in English yet so I don't know if they have complications later on.

The cpu core is the best of _all_ emulators regardless of platform, graphics wise it has some issues though.
I'm sorry, I guess I'm out of the loop, what do you mean "cpu core?" Is that like a retroarch core? I was just curious if there was still any reason to keep dualSwan around.. Which it doesn't really seem like there is :P

Anyways, I will say thank you regardless, it is awesome to have (so many!) up to date emulators for the DS family... You are doing gods work!

I'm not exactly an emulator developer, so take this with a grain of salt, but from what I understood all emulators rely on separate cores to replicate a certain console's hardware functions. For example, NitroSwan has a CPU core, a VDP/GPU/whatever you want to call it core and an audio core, plus other things related to stuff like the refresh rate and memory timings. Higher core accuracy is generally a good thing, but they will also be slower on old hardware like the DSi

Okay, I didn't know there were cores outside of RA.. huh. So, if NitroSwan uses the cpu core, what does dualSwan use? The same thing? (maybe somebody knows?) I guess for the time being I will just use NitroSwan since it still gets support.. Unless dualSwan runs better on flashcards or something idk.

Dualswan is written in C language. Nitroswan is written mainly in Assembly (so they are two different emulators with two different programming approaches). This means that nitroswan has low level access to the hardware (more efficient use of the ressources). You can reach very optimized code to specific requirements. If today with our newer CPU's (with their instruction sets), Assembly is not a must, for weak CPU's like the one in the DS it is better in terms of performance. Assembly language is difficult and you need to know very well the hardware it will run on (and the one emulated). Flubba is very skilled.

Dualswan is outdated, it was not fullspeed AFAIR so stick with Nitroswan.

I try to keep different parts of the machine in separate logical "structures", in this case a source repository/folder.
Now the V30MZ cpu is not used in any other machine except the WonderSwan, but take the 6502 is used in _many_ machines so the exact same source code is used in a lot of my emulators without modifications. So in this case "core" is just something that is more or less pluggable into the other parts of the emulator, kind of like emulator cores in RA.
