Homebrew RELEASE melonDS for Switch — continuation

[sj33]

Hugely impressed with the progress. Playing Apollo Justice: Ace Attorney and it's not dropping a frame.

Awesome. Thanks and I click this thread to watch your progressing. Keep up the good work!

Seems all roms are crashing for me upon boot.

• Running SX OS 3.0.4 on a SX Lite installation for the Switch Lite (for which atmosphere is not available),
• I've tried running with full ram access while holding R over a title
• Also I've also tried using an NRO forwarder (which I also can't seem to run individual games with, only the main application appears, but that's no big deal).
• Checked the MD5 sums of my bios and firmware, they all check out
• SD Card is fat32

EDIT: Did some tinkering, seems that turning off fast memory fixes it. It causes slowdown, but at least they run.

No CFW besides Atmosphere is supported. In this case I'm sorry because there's no hack for patched Switches yet, but if they break things reguarly there's nothing I can do about it hence this policy.

Out of curiosity, what does the "fast memory" feature/option do?

Out of curiosity, what does the "fast memory" feature/option do?

it takes a bunch of virtual memory and mirrors memory into it so that it matches the memory layout on the DS. Thus most memory accesses can be translated to nothing more than adding the address from the DS side to the start of that virtual memory region and making a load or store. Flycast uses virtual memory tricks as well (though fastmem like melonDS does it, is not supported on Switch, it only uses it to detect reads/writes to texture memory by modifying page permissions).

Hi ! FYI you can run melonds with fast memory option enabled on atmosphere but you maybe already knows that. Good evening

There is a bug in pokemon black and white where if you go to save in game it gets stuck on the save screen and there is no way around it you have to reset your progress

is the text indicating your play time corrupted with a bunch of question marks?

I hoped this bug wouldn't happen on Switch, as those are very popular games and I had no report before, but here we are. Apparently disabling the C-Gear prevents it. The underground in D/P/Pt is affected by this as well. Besides it being related to local wireless we unfortunately don't have a clue of what's going on.

I understand. I'll just have to deal with it until SX allows for other firmware on their chips.

when i load up melonds, the input is weird. the left stick is in reverse for some reason, and the face buttons are sideways. anyway i can fix this?

With the sx os payload you should be able to launch external payloads, like hekate. You would need an extra step but it should be possible to go through options launch external payload/hekate and launch atmosphere?
Otherwise have you tried switchroot, it has Drastic which pretty much runs all DS at full speed, it will never get a switch port because it is 5$ or so service, however on switchroot if you install magisk you can avoid the cost if you so chose.
I dont have sx core or lite but in theory all the above should work on either .

I appreciate your suggestions but many of them are not possible.

• Switch Lite/Core cannot boot Hekate currently.
• Switchroot is not working on Lite / Mariko units.
• Drastic is going open source this year (supposedly, the developers said this over a year ago) so we will undoubtedly see a port to Switch soon after.

There is no question marks its just would you like to save the game press yes and the music is still playing and your character is stuck there and it doesn't load

it still sounds an awful lot like that bug. There's another indicator, is the wifi connection strenth meter red with no connection?

No weirdly I can send screenshots the wifi bar is full green as if you have wifi yet you can't connect to online which is expected

The Atmosphere team are actively working on Mariko support though, so at the very least you should soon be able to boot Atmosphere through fusee-primary.

I'm excited at the prospect, but I'm not sure if it entirely depends on them or if SX must also do something to enable running atmosphere.

Fast memory emulation doesn't work on sxos (Mariko) but every game I've tried works perfect with a slight overclock. Great work!

Yeah I've noticed the same thing. Although I don't get 100% even with a slight overclock.

What games are you trying? I haven't tried a ton but judging by the audio and my eyeballs, it's pretty spot on.
