Homebrew WIP melonDS for Switch

[thathuttsfollower]

ok, here is it now, a small update, with all of the changes which accumulated over the week.

Changelog:

• Fix Dragon Quest IX whitescreen while booting
• Fix Pokemon White/Black(haven't tested the latter) not saving
• Added error message, which is displayed when files are missing/couldn't be found
• Clicking on gui element on top of the emulated touchscreen is now only registered a gui click
  
• Allow booting games via the bios menu, uncheck boot directly to do so
• Audio output is rewritten to use audren. This fixes sound not working after going into homemenu/sleep. As a positive side effect, sound is now also recorded when using HOS clip capture feature
• By pressing the left stick down microphone (noise) input is simulated
• Allow for turning off literal optimisations, if a game doesn't work properly please report whether this and/or turning off branch optimisations helps!
• Some other small bugs.

Please note that I want to focus fixing bugs and improving performance of the emulation itself. So expect to see only minor improvements on the interface side for the time being (except save states, I just noticed that those would be quite useful to have them for debugging).

EDIT: it's DQ 9 not 11
EDIT2: here's a build which also allows to open and close the lid, as requested by @angelhp

DAMN! The build is really amazing, and runs games almost twice as smooth, all the stuff's customizeable.. but there's one problem: how to create savefiles? i mean, sure, playing a little bit of new soup or diy on a switch is amazing.. but ya gotta be able to continue. So i guess.. tell me how to create savefiles or imploment the feature..? that'd be amazing

If you played DS games on Drastic before (f.e. on Switchroot (Android for Switch)), here is how you bring over savegames:

I've just done so - works.

cheats are currently not supported in melonDS at all. Some people use this: https://gbatemp.net/threads/ds-auto-trainer-maker-dsatm.80540/ to directly inject the cheats into the rom.

Thanks. But the link seems to be down.

you need to use title injection (so not album). Most 3d games only run at fullspeed with a high overclock setting. Do you use the latest version(https://gbatemp.net/threads/melonds-for-switch.518300/page-35#post-8830041)? The old one didn't check if you have all of the files in place, this one does.

is there a framerate limit hotkey to turn off frame limit?

 

[catlover007]

is there a framerate limit hotkey to turn off frame limit?

no, emulation is currently bound to vsync, approximately 60hz

any update ?

Besides school I wasted some time on a stupid project which never will work anyway. A few days ago I finally got back to optimisations, working on the GPU2D rewrite. I did some optimisations on this side before, but there weren't very cleanly integrated and I noticed arm neon with intrinsics is still doesn't give optimal code, atleast with GCC 8.2 which is what devkitpro provides. That's why I'm going with inline assembler now, register scheduling can be tricky, but I hope I'll do a better job than the compiler. When it's finished it the whole optimisation hopefully is in a state that it can be included in main melonds. It should also be faster too.
After thinking about this, I probably should have finished up all of the interface additions and bug fixes and released that.

Anyway that's the current state of this project.
