melonDS 0.7 is out!

This release savestates and some other things.

The full changelog is below.


• fix possible crashes when exiting
• wifi: add basic access point melonAP (very beta)
• fix SMULWx/SMLAWx opcodes, fixes Sims 2 music
• add support for loading BIOS/firmware files and config file from AppData or ~/.config/melonds or from the executable directory (hcorion)
• add 32-bit IPCSYNC reads/writes (Dirbaio)
• add savestates
• 3D: (hopefully) fix bug in shadow/AA interaction (visible in the MKDS character select preview, bottom border of the platform thing)

How to use

melonDS requires BIOS/firmware dumps from a DS. You can dump them with the following dumper.

The files must be placed in the same directory as the melonDS executable, as follows:

* bios7.bin -- ARM7 BIOS, 16KB
* bios9.bin -- ARM9 BIOS, 4KB
* firmware.bin -- firmware, 128KB, 256KB or 512KB

Note: the DS-mode firmwares in the 3DS and DSi aren't bootable. They only contain the bare minimum required to run DS games. Be sure to enable direct game boot when using such firmware dumps.

Settings

Emulation: settings related to emulation. For now it lets you enable direct game boot (directly runs the game instead of going through the firmware) and the threaded 3D renderer.

There's also a wifi-related setting (which only ended up there because I'm lazy and I need to redo the UI). You should try toggling it if you have trouble getting multiplayer working.

Input: allows you to configure keyboard and joystick input. You can change a mapping by clicking the corresponding entry, then pressing a keyboard key or joystick button. For now, joystick input uses the first joystick available if multiple joysticks are plugged.

Savestate settings: for now, whether to save to a separate savefile after loading a savestate.

Screen rotation: lets you rotate the screens, for games that ask you to hold your DS sideways.

Screen gap: sets a gap between the screens.

Screen layout: natural (screens always stacked on top of eachother), vertical (screens always laid out vertically), horizontal (always laid out horizontally).

Screen sizing: even (both screens get the same size), emphasize top (bottom screen is kept at native resolution), emphasize bottom, auto (tries to determine which screen to emphasize)

Screen filtering: enables linear filtering when the screens are scaled.

If your game fails to save

Check the size of the savefile. melonDS can, in some circumstances, misdetect the save memory type.

Save memory type detection is done only when no existing savefile is present.

If you provide an existing savefile with the correct size, melonDS will use the correct save memory type and saving should work properly.

it doesn't use the GPU so I doubt that's in cause except for drawing the final screen, but huh, 'd be weird af if that crashed

anyway, that's weird

do older builds still run fine even when downloaded fresh?

mhh

take a screenshot of the directory melonDS 0.7 is in? with all the files

that's 0.6 you've got there, not 0.7

other than that, all the files seem to be here and good

ninja'd

anyway might have to do with not finding melonDS.ini, there was a related bug but weird shit

check the archive you downloaded -- I had updated it to include a stock melonDS.ini so this wouldn't happen

well there were multiple issues in some code meant to look for config files in AppData

* got a string buffer with the appdata path base, resized it, but didn't complete it, leaving the end uninitialized
* CoTaskMemRealloc() can move the buffer if needed, which was not accounted for, so possibly trying to access freed memory

ie. bad bad bad

and likely why it crashed at random

AppData/Roaming/melonDS

you can put melonDS.ini and BIOS/firmware there if you wish. you don't have to.
