    Coto updated the experimental Branch again.

    F-Zero and Donkey Kong Country 3 are working again.

    I have posted the latest Version below.

    Thank you @Coto for your continuing support of SNEmulDS.

    it isn't working for me. This new version won't let me choose my roms.

    This Version requires the snemul.cfg that came with the build to choose the Snes roms. I reuploaded the Update with the needed snemul cfg.

    Oh and changing the Speed settings while playing F-Zero breaks the Game in this Version.

    well your feedback is valuable also! so thanks there. SnemulDS uses the DS in a way where the APU (SNES) emulation cause issues if both cores (ARM7 / ARM9) do not run properly. Also before I write emulation code I want to enable most DS specific stuff before (so the library can be used whatever the homebrew is).

    This worked for NIFI on SnemulDS (not implemented), but DSWIFI works now

    Oh my! Thanks @Coto for your work on this! I'm trying to get Zelda A Link to the Past to work more or less properly. It plays, but there is a lot of noise/very loud background sounds. For example the rain in the very beginning after leaving the house. Any tips on how to improve this with config?

    Thanks @Coto for keeping this project alive!
    One question: is it possible\hard to add ARG support to the experimental branch?

    emulator stuff is not high priority now, I am moving to a new toolchain and then other stuff. Hopefully fixes a bug that exists since the first "revival" version (related to opcodes2.s) compiling and mapping.

    I would rather stay away from ARG support since requires to be implemented from the homebrew launcher and homebrew itself. For example ninjapass works now with moonshell2 properly, and moonshell2 has that extlink support(and through Moonshell2 I load SnemulDS), so if I want to use such an old card for updated dldi compatibility I would force extlink support, and that means old cards no longer having file/dir handling at boot (a basic feature required for debugging..).

    edit: though there are other homebrews that may benefit from ARG support.

    @Coto
    Is it possible to have a DSi (or nds-bootstrap) compatible version of SNEmulDS?

    Perhaps @Robz8 since him uses built-in emulators into his SRLoader.

    You should not offer devs to do these kind of stuff without asking them first. Privately at least. That´s why PMs exist.

    Also, for DSi mode you break everything that works different in DS mode (wifi, sound, touchscreen,new SCFG registers). I am 90% done with the toolchain for NDS, so for now every DSi dev will have to use what already exists for DS(i) mode.

    I see, I guess is currently imposible to have a TWL edition working but.
    How about @ahezard's nds-bootstrap?
    It proved that it runs NDS only homebrews with older dldi driver, last I tested it broke snesmul into the guru meditation screen.

    Nvm, looks like SnemulDS (build from experimental branch) works flawlessly with lastest nds-bootstrap. Can't wait to test it on HiyaCFW :)

    that's a dilemma tbh.

    Port everything to DSi, or tweak SCFG so they run in NTR mode. It´s no minimal the effort to port something. Add that the double testing (I test DS stuff on three flashcard, 6 DSes), because the more you know, with minimal details such as some cards raising IRQs by themselves allow to run homebrew, while the exact homebrew will not run on certain carts. That's triple testing for me on the IRQ system. (my own current DS toolchain gave me these results)

    also, snemulds + wifi (NTR Mode, DS hardware) is very tricky to set up. NesDS works out of the box(NIFI and WIFI UDP NETPLAY), gbaemu4ds (a build that I never released) also uses DSWIFI and works almost flawlessly except the irq system needed a rewrite because of how close to hardware and MPU is used. (froze up back then when gba code called wait for vblank swi, but wireless still worked)

    But snemulds is different, or "special". It either causes wifi (DSWIFI) to not connect or works, but break sounds.

    edit: turns out SnemulDS dswifi was borked because the original programmer used timer3 in ARM9 as profiler for render code. It was enabled by default, so I removed all that code and everything is working now.

    Wow, when I run SNEmulDS with nds-bootstrap + TWL Clockspeeds it goes insanelly overclocked!!! I can't imagine how improved will be emulation on DSi with the new homebrew envoirement.

    Sadly the last version you posted does not work for me, it shows me no roms at all and when pressing "SELECT ROM" it shows me a red windowed errorlog, with and wihtout CFG file.

    The previous version you posted works fine though.
