Analogue Hardware

Manage Analogue FPGA consoles: Pocket, Mega SG, NT / Super NT, and 3D.

Analogue Pocket

Manage the Analogue Pocket SD card: browse cores, export screenshots, backup and restore saves, manage save states, extract Game Boy Camera photos, and generate library images.

SD Card Setup

Click Browse SD Card and select the root of the Analogue Pocket SD card.
The tool validates the card by checking for expected directories (Cores/, Platforms/, Assets/).
Once loaded, all Pocket management features become available.

Features

Feature	Description
Browse Cores	Lists all installed openFPGA cores with platform, version, and size
Export Screenshots	Copies all screenshots from the Pocket to a chosen folder
Backup Saves	Backs up all save files to a destination folder, preserving the directory structure
Restore Saves	Restores saves from a backup folder to the Pocket SD card
Manage Save States	Lists save states with platform grouping; select and delete individual or batch states
Export GB Camera Photos	Extracts photos from a Game Boy Camera `.sav` file and exports as grayscale BMP images
Auto-Copy Files	Copies files from a source folder to the SD card, matching the directory structure
Generate Library Images	Creates placeholder 160×144 BMP images for ROMs without library art
Open Game Folders	Lists platform folders under `Assets/` for quick access in the file explorer

Analogue Mega SG

Generate custom fonts for the Analogue Mega SG on-screen menu and convert save files.

Font Generator

Select the Mega SG SD card root.
Optionally select a 128×128 BMP source image (16×16 grid of 8×8 character tiles). If no image is provided, the built-in default font is used.
Click Generate Font to create the font binary and save it to the System/ directory on the SD card.

Save File Converter

Browse and select a save file (.sav, .srm, .eep, .fla, .sra).
The tool analyzes the file and displays its size, detected type (EEPROM, SRAM, or Flash), and power-of-two alignment status.
Select a conversion type:
- Swap Endian 16-bit — swap bytes in 16-bit pairs
- Swap Endian 32-bit — swap bytes in 32-bit groups
- Pad to Power of Two — pad to the next power-of-two size for flash cart compatibility
- Trim Trailing 0x00 — remove trailing zero padding
- Trim Trailing 0xFF — remove trailing 0xFF padding
- SRM → SAV / SAV → SRM — convert between save formats
Click Convert to create the converted file alongside the original (with _converted suffix).

Analogue NT / Super NT

Generate custom fonts for the Analogue NT and Super NT on-screen menus and repair NES ROM headers.

Font Generator

Select the NT or Super NT SD card root and the target console (NT or Super NT).
Optionally select a 128×128 BMP source image. If none is provided, the built-in default font is used.
Click Generate Font to create the font binary on the SD card.

NES Header Repair

Select a NES ROM file (.nes).
Click Repair Header to fix common header issues.
The repair uses a safe temp-file workflow: writes the fixed ROM to a temporary file first, then replaces the original only on success.

Analogue 3D

Manage N64 Game Pak ROMs on the Analogue 3D SD card with per-game display and hardware settings.

SD Card Setup

Click Browse SD Card and select the root of the Analogue 3D SD card.
The tool validates the card by checking for expected directories (System/, N64/).
Click Scan Game Paks to list all N64 ROM files on the card.

Per-Game Settings

Click a Game Pak to open the settings editor:

Display Settings:

Setting	Options
Resolution	Auto, 240p, 480i, 480p
Aspect Ratio	Auto, 4:3, 16:9
Smoothing	Off, Low, Medium, High
Crop Overscan	On / Off

Hardware Settings:

Setting	Options
Expansion Pak	On / Off
Rumble Pak	On / Off
CPU Overclock	On / Off
Controller Pak	Auto, None, Memory

Settings are saved atomically (writes to a temp file first, then renames) to prevent SD card corruption if the write is interrupted.

Label Artwork

With a Game Pak selected, click Set Artwork to assign a custom PNG label artwork image for the game.
