Load up your SD card

Pick your card below. Retro handhelds get the best English walkthrough saved as a .txt next to each ROM. TWiLight Menu++ cards — DS flashcarts like the R4, modded DSi, modded 3DS/2DS — get every walkthrough as an in-game manual: pause the game, read the guide, resume. Everything happens in your browser, nothing is uploaded; guides come straight from the GameFAQs text archive on archive.org.

RETRO HANDHELDS
1 · You pick the card's Roms folder (or the card root, it finds Roms).
2 · Game names are matched against the GameFAQs index, right in your browser.
3 · The best English walkthrough per game is fetched from archive.org and saved as Game Name.txt next to the ROM. Existing .txt files are never touched.
Works with stock Anbernic, OnionOS, GarlicOS-style folder names (FC, SFC, MD, PS…).
TWILIGHT MENU++ · DS / DSi / 3DS
1 · Pick the card root. The tool spots _nds/TWiLightMenu and switches to manual mode — same card layout on an R4-style flashcart, a modded DSi, or a modded 3DS/2DS.
2 · Your DS games are found wherever they live — card root (R4 style), roms/nds, or your own folders — and matched against the GameFAQs DS index.
3 · Each walkthrough is reformatted for the DS screen (32 columns, plain text) and saved to _nds/TWiLightMenu/extras/manuals/ under the ROM's own name. Existing manuals are never touched.
4 · On the console, launch the game from TWiLight Menu++, then press L + Down + Select in-game and choose Manual… — that's your walkthrough, game paused while you read. HOME-menu forwarder icons reuse whatever TWiLight launched last, so launch through TWiLight Menu for the right guide.
DSPICO
1 · Cards with a _pico folder are detected as DSpico flashcards. Your games are found anywhere on the card and each walkthrough is saved as plain text in a guides/ folder.
2 · Not just DS: .gba, .nes, .smc, .sfc, .gb, .md and the rest are matched against their own console's index, so an emulated game gets a guide too. They all share the one guides/ folder, so a game you own on two systems resolves to a single guide.
3 · On the console, guides are read on the DS itself. Run the DS-BIOS Pico Launcher and press the book button in the app bar — the highlighted game's guide opens on the top screen.
4 · UP/DOWN scroll a line, L/R a screenful, and text reflows to the screen. Pick another guide from the list, and every guide remembers where you left off.
