Remember the old days of having forwarder channels on your Wii that boots games from your USB drive or SD Card? Ever wanted a way of launching full DS games like digital titles in your 3DS HOME Menu? Well now you can! In this turorial, you can make forwarder CIAs that boots NDS ROMs from an SD Card (or if you want, a DS-mode flashcard). Requirements 3DS: GodMode9 A CFW that patches TWL_FIRM (Luma3DS) A CIA installer (FBI, DevMenu, etc) An SD Card (or microSD card for N3DS) (Optional) DS-Mode flashcard (aka, Slot-1 to microSD card adapter) Flashcard list (skip if you want to use SD Card) The recommended flashcards are DSTT and Acekard 2i (and R4 Ultra too, since that's an ak2i clone). If you want perfect game compatibility, get the SuperCard DSTWO/DSTWO PLUS. The only downside is that it drains your system battery faster. If you have a flashcard that works with @Apache Thunder's NTR Launcher, fell free to request it here. Be sure to specify which build you're using (Normal or Alt), and if RESETSLOT1 is set to 0 or 1 in "sd:/nds/ntr_launcher.ini". Compatible: Acekard 2(i) (DSi-Enhanced games, including newer NTR games, don't work.) Acekard RPG DSTT DSTT Advance Galaxy Eagle M3 DS Real M3 DS Simply (uses <2GB microSD card) R4 DS (Original Non-SDHC version, uses <2GB microSD card) R4 SDHC Snoopy R4 SDHC RTS LITE (www.r4isdhc.com) R4 SDHC Upgrade (www.r4i-sdhc.com) R4i3D (www.r4i3d.com) R4iDSN R4i Gold R4i Gold RTS (www.r4ids.cn) R4i-SDHC (www.r4i-sdhc.com) (Normal and RTS versions) R4iTT (www.r4itt.net) (Purple card may be incompatible) SuperCard DSONE SuperCard DSTWO (Normal and Plus versions) Untested: R4i3D NEW (Use R4iDSN template and pack) Partially compatible: Ace 3DS+(Game compatibility is bad, so saving/loading save file results in crashing.) Gateway Blue Card (Game compatibility is bad, so saving/loading save file results in crashing.) EX4DS (Game compatibility is bad, so saving/loading save file results in crashing.) R4iLS (Game compatibility is bad, so saving/loading save file results in crashing.) Cards with www.r4isdhc.com.cn (Game compatibility is bad, so saving/loading save file results in crashing.) Incompatible: CycloDS (i)Evolution (Can autoboot ROMs, but it works differently than other flashcards.) (i)Edge (Unable to autoboot a .nds ROM) R4 Gold Pro (www.r4i-gold.com/www.r4i-gold.me) (YSMenu (not the forwarder process) bricks the card) R4i3D (2012) R4 Infinity Dual Core R4 SDHC R4 SDHC Dual-Core (www.r4isdhc.com) (YSMenu (not the forwarder process) bricks the card) Windows/Linux/Mac: Latest Java version Linux: JavaFX SD Card users: See what games work and what doesn't work: https://docs.google.com/spreadsheets/d/1M7MxYQzVhb4604esdvo57a7crSvbGzFIdotLW0bm0Co/edit#gid=0 Download a pack for your card (forwarders won't run without it): 3DS SD Card Flashcards Original R4/M3 Simply Acekard 2(i)/M3DS Real DSTT/R4i Gold/R4i-SDHC/R4 SDHC Upgrade/SC DSONE Acekard RPG R4iDSN/R4i Gold RTS Ace 3DS+/Gateway Blue Card/R4iLS/R4iTT SC DSTWO and let's not forget: Forwarder3-DS (Current version: v2.9.6) also, check out: Animated banner icons for your forwaders! For hacks/translations of DSi-Enhanced games, find a fixed banner above. Source code for the templates (not needed): https://github.com/Robz8/NTR_Forwarder/ For SD card Extract what's in "for SD card root" to the root of the 3DS SD card. For flashcard Extract what's in "for Slot-1 microSD" to the root of the flashcard's microSD card, and (if folder exists) "for 3DS SD card" to the root of the 3DS SD card. What will be in each pack for loading ROMs: Original R4/M3 Simply - WoodR4 & YSMenu DSTT/R4i Gold/R4i-SDHC/R4 SDHC Dual-Core/R4 SDHC Upgrade/SC DSONE, Acekard 2(i)/M3DS Real/R4i-SDHC 1.4.x - YSMenu Acekard RPG, Ace 3DS+/Gateway Blue Card/R4iLS/R4iTT, R4iDSN/R4i Gold RTS - WoodR4 Part 1: GodMode9 (Skip, if you already have the ROM(s) you need) Make sure you have your DS game cart inserted. Hold START on boot to bring up the payload selection menu. Select GodMode9. At [root], select GAMECART. Copy the .nds or _trim.nds file, to "sdcard:/roms/nds". When you're done dumping your ROMs, power off the system. Part 2: Forwarder3-DS Select the target card you're using on the left. Check "Automatically set ROM path" to set the path to where your ROM is at in the SD Card or flashcard. Warning for Linux users: The automatic path is incorrect since it includes the entire path (e.g. /media/$USER/something/). Click the folder on the top-right, and find the ROMs on the SD Card (or flashcard) you are using, or drag and drop them into the window. If you're playing a hack/translation of a DSi-Enhanced game that has it's banner/title edited, find the banner for the game above, right click on the game in Forwarder3-DS, click "Import banner", and click on the banner to use. If using a homebrew ROM, click on it, then clear and type in the game title. Click the floppy drive button to generate the forwarder CIA! Copy the CIA to your 3DS SD Card, or put it in Boop for network installation. SD users: Make a Mario Kart DS CIA, install it, launch it, and after the DS boot screen (or a few seconds of a white screen, if that is off), the ROM will be set as donor ROM. Install the CIA(s). If using EmuNAND, install it to both Sys & Emu NANDs. You are now done! Enjoy your forwarder CIAs! After you extract the pack for your card, you can edit "sd:/nds/ntr_forwarder.ini" and change one of the settings. This isn't possible for Acekard RPG, R4 DS, and R4i Gold RTS. NTRCLOCK: If set to 0 or if A is held, the DSi boot screen will appear instead of the normal DS splash, and TWL clock speed is used, so lags begone. (Not for SD card users, as that setting is in nds-bootstrap.ini, as BOOST_CPU.) DISABLEANIMATION: If set to 1 or if B is held, the DS/DSi boot screen is skipped. HEALTHSAFETYMSG: If set to 1, the boot screen's H&S message will appear on the bottom screen. If set to 0, the bottom screen stays white with no H&S message. SOUND_FREQ: (Only for games on SD card.) If set to 1, sound will play at 48khz, instead of 32khz. Here's a video tutorial and a forwarder in action! (This was before we were able to run retail ROMs from SD Card.) Credits: @Olmectron, for making Forwarder3-DS. Me, for creating the Auto-Boot ROM Path setter for DSTT/R4i Gold/R4i-SDHC/R4 SDHC Dual-Core/R4 SDHC Upgrade/SC DSONE, Acekard 2(i)/R4iTT, and DSTWO. @ahezard, for making the R4/M3, Acekard RPG, R4iDSN/R4i Gold RTS forwarder templates, and nds-bootstrap. @Apache Thunder, for recreating the DS/DSi boot screen. @MasterCheese, for helping me getting the Ace3DS Plus, Gateway Blue Card, and cards with www.r4isdhc.com.cn to work. FAQs: Q (Linux users): Why is Forwarder3-DS not starting? A: JavaFX isn't installed. Please install JavaFX. Q: I'm not getting a CIA, just a .nds file. Why? (or: Why is the banner/title blank?) A1: Make sure your ROM's .nds filename is short, and/or create Forwarder3-DS folder in your hard drive (or flash drive) root, and run the .jar file there. A2 (Linux and MacOS users): Execute chmod +x make_cia in the terminal on the .jar file's directory, so that make_cia gets the needed rights to be executed. Q: How do I update the forwarder templates? A: The app will automatically update the templates if it's set, or you can click the button next to the Forwarder3-DS title, and click "Update templates". Q: How do I get rid of lag on games? A: Hold A before the DS boot screen appears, or open "sd:/nds/ntr_forwarder.ini" ("sd:/_nds/nds-bootstrap.ini for SD card users) and set NTRCLOCK (BOOST_CPU for nds-bootstrap.ini) to 0 (1 for nds-bootstrap.ini) to use TWL clock speed. Q: Why aren't some of my forwarders appearing? A: You went over the 40 DSiWare game limit. Copy any DSiWare/forwarder you don't use, to your SD Card, and delete it from System Memory. Q: Will the game I'm playing show up in Activity Log? A: Yes it will! Q: What games are DSi Enhanced (have animated banners)? A: Look here. Q: Why am I taken to a ROM selection menu? A: Make "Games are on SD card" was checked, and you dragged and dropped the ROMs from the flashcard's microSD, to Forwarder3-DS' window. Q: Will this load DSi enhanced games in DSi mode, including DSi exclusive games? A: Nope, but maybe in the future, since we can run commercial/retail ROMs from the 3DS SD Card. Q: How do I use cheat codes? A: Use this program. FAQs: Flashcards R4 DS/M3 DS Simply, R4iDSN/Acekard RPG/R4i Gold RTS: Q: Why are some of my games getting white screens? A: The forwarders are based on an outdated version of Wood, which had it's source code found. The version used has bad compatibility with some games. Open _wfwd/wfwd.ini, and set useLatestWood to 1. DSTT/R4i Gold/R4i-SDHC/R4 SDHC Dual-Core/R4 SDHC Upgrade/SC DSONE, M3DS Real: Q: Why does my game freeze sometimes? A: The game has Anti-Piracy checks. YSMenu is supposed to fix that, but won't for some reason. Q: Launching the CIA just takes me to the ROM selection menu. How do I fix that? A: Delete or rename any existing YSMenu.ini file in the YSMenu and root folders/directories. Q: How do I skip to the ROM selection menu? A: When booting YSMenu, hold B to go to the ROM selection menu. Q: Why am I getting: [Rom Loading failed] load rom errcode=- Please reset system. A: Look at the YSMenu error code guide.
