Homebrew WIP melonDS for Switch

[FanNintendo]

the DS's is a very quirky and nonstandard piece of hardware. Using the native drawing capabilities of a modern GPU will always fall short in some games (and I'm not even talking about less popular games "no one cares about"). melonDS's OpenGL renderer still lacks one hack or another which could make some games work which currently don't, but there are absolute limits to how far this can go.

For this reason I prefer optimising the software renderer, which if everything goes right makes almost all games playable. Also for standalone I moved on from OpenGL to deko3d because it's less bloat and it didn't have that mysterious slowdown OGL while only drawing the GUI had. Porting the GL renderer to deko3d wouldn't be so hard, as it's pretty lightweight and doesn't compile any shaders at runtime, but that's a story for another time.

There's the "hidden third path": running the software renderer via compute shaders on the gpu. Idk whether the switch's gpu is powerful enough for this, especially considering that some OGL extensions aren't available which could make the shader code faster (small integers).


citra won't emulate it, as it only supports the 3DS hardware, the DS/i hw is completely unsupported

thanks its good to know i have 2 different format of dsi files one is .ds and one is with 8 digitals i been asking around what is 8 digital is so i googled. it is like wup install something like that so kept them in future if it is worth good

I did some more testing on the docked/undocked overclock bug and I think I figured it out now.

The overclock does indeed persist through docking and undocking usually. There's one exception though: If you put the Switch in the dock and remove it again without leaving sleep mode while it's docked, the overclock does not persist.

more info please. Do you use the version linked in my signature? Do you use Atmosphere? Which FW version do you use? Do you use title injection to launch the hbmenu?

Im using the 8.3 version that is in the main post.

[ComicMaster148]

Yes I use atmoshpere, Firmware 9.10, and yes

 

[catlover007]

Yes I use atmoshpere, Firmware 9.10, and yes

do you have all the files in the right place on the sd card (/melonds/bios9.bin /melonds/bios7.bin /melonds/firmware.bin /melonds/romlist.bin)?

 

[ComicMaster148]

Yes I have them all

 

[catlover007]

Yes I have them all

weird, does other homebrew work for you?

I'm pretty much through with my standard questions. Maybe try deleting the config files in /melonds?

 

[ComicMaster148]

Yes other homebrew works for me currently im playing on ppsspp on my switch. And I will try deleting that file to see if something changes.

Nope it crashed again when I tried to launch a game

ah, didn't catch that, it only crashes after you start a game.

You probably tried starting different games, just to be sure? Can you compare the checksum of your bios and firmware files with those found here: https://drastic-ds.com/viewtopic.php?t=5417 ?

 

[ComicMaster148]

The size is the same although I dont know how to confirm the MD5

this website should work http://onlinemd5.com/

My checksum does not not match any other my chcksum 3C704824663CE26B6A1ED4D85238AE5B
