SnemulDS [Revival] is a continuation project of SNEmulDS, a SNES emulator for the Nintendo DS.

This is based from the original SNEmulDS sources by archeide (in between 0.5 and 0.6a).

Features

• SPC Jukebox.
• Hotkeys to swap screens while running a game.
• Key mappings.
• Save/Load States.
• ARGV Support.

Installation

Download contains multiple branches:

• TGDS1.65 - Latest release.
• TGDS1.6 - Branch for stable features (latest stable release).
• TGDS1.6 Singles - Contains precompiled arm9dldi version (with some additional features).
• master - Development branch.

To install, go to the release folder and copy these files to SD:/root:

• snemul.cfg.
• Either /arm7dldi-ntr/SnemulDS.nds (NTR mode) or /arm7dldi-twl/SnemulDS.srl (TWL mode).

Create a snes folder in SD:/root, and put your homebrew games on it.

For SPC playback (optional), create a spc folder in SD:/root, and put your SPC files on it. You can choose and play a SPC File in the SPC Jukebox option.

User guide

Hotkeys

While SnemulDS is running a game, it is possible to use hotkeys to swap Menu Screen/Emulator framebuffer between Top/Bottom Screen.

When framebuffer is set to bottom screen, the top screen will turn off.

Remap NDS to SNES Keys

Go to /release/snemul.cfg, section: KEYS and copy/paste source value into target field, then restore original overwritten value into source field.

Save changes, then copy snemul.cfg in SD root. Keys are remapped now.

Save/Load States

It is experimental. It may or not work consecutively. It's recommended to always save then restore a single state at a time.

To properly Save/Load SRAM:

• Save in-game, check Options -> SRAM saving and wait for a SRAM written message to appear.
• Right after uncheck this option before reloading other games or shutting down console.
• This ensures your savefile is kept safely.

Controls

L+R+Start+Right - Swap Menu Screen between Top/Bottom Screen (in game only)

Compatibility

Works with NTR compatible Flashcard and TWiLight Menu++.

Tested by the author with X9SD, R4IGold.cc, DeSmuME and no$gba.

Changelog

0.6c

• Fix TWL mode touchscreen.

0.6c alpha

• TWL support. Currently tested on no&gba. Some lag may happen between loading screens.
• Fixed a ton of issues (a work of at least 3 years, related with TGDS SDK, mostly memory issues, codebase stability, interrupts, arm7 dldi support, arm7 sd twl support, etc).
• Fixed codebase mostly to have a better user-experience, and of course all the changes were merged into NTR version as well.

0.6b

• Fix compatibility with more cards, also restored compatibility to be the same as the one developed by Archeide.

0.6a

• A ton of stuff. Add SnemulDS to TGDS. NTR mode only.

0.6

• Used old SnemulDSx sources, which were broken.
