Description

Clarifies the Expansion Pak status wording shown on the ROM information screen.

This changes the displayed labels as follows:

  • SuggestedEnhanced
  • Not requiredNot used

No ROM database values, Expansion Pak detection logic, or boot behavior are changed.

Motivation and Context

The current wording can be misleading when compared with the underlying ROM metadata.

ROMs marked with the database flag FEAT_EXP_PAK_ENHANCED are currently mapped internally to EXPANSION_PAK_SUGGESTED, which is then displayed as Suggested. Displaying this as Enhanced more accurately reflects the database metadata.

Likewise, Not used is clearer than Not required for titles that do not use the Expansion Pak.

Closes #310.

How Has This Been Tested?

The change is limited to two user-facing strings in format_rom_expansion_pak_info() and does not modify ROM metadata handling, Expansion Pak detection, or ROM loading behavior.

The repository's automated build workflow will validate the change when the PR is submitted.

Screenshots

Not applicable.

📝 Walkthrough

Walkthrough

The menu adds file-type sprite assets and rendering, adds SNK Neo Geo emulator configuration, and updates Expansion Pak status labels. VS Code configuration and the libdragon reference support the sprite build and development setup.

Changes

File-type sprite rendering

Layer / File(s) Summary
Sprite contract and assets
.gitignore, .vscode/c_cpp_properties.json, Makefile, libdragon, src/menu/ui_components.h
The project defines file-type sprite values, includes sprite assets in the filesystem, compiles menu/sprites.c, preserves the VS Code configuration, and updates the libdragon reference.
Sprite loading and rendering
src/menu/sprites.c, src/menu/menu.c
The menu loads registered sprites during initialization and draws loaded sprites with RDPQ.
File-list sprite integration
src/menu/ui_components/file_list.c
The file list uses file-type sprites and displays directory markers in the right-aligned column.

SNK Neo Geo loading

Layer / File(s) Summary
Neo Geo emulator type
src/menu/cart_load.h, src/menu/cart_load.c
The loader defines the SNK Neo Geo emulator type and maps it to the neogeo configuration with mvs64.z64 as the default ROM filename.
Neo Geo display and detection
src/menu/views/load_emulator.c
The emulator view formats the SNK Neo Geo name and comments out automatic Neo Geo extension detection.

Expansion Pak labels

Layer / File(s) Summary
Expansion Pak status text
src/menu/views/load_rom.c
The ROM information view uses “Enhanced” and “Not used” for the affected Expansion Pak statuses.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to e61fd

The PR adds Neo Geo loading support, but the file-detection path remains disabled, so matching files may still be rejected as unsupported instead of using the new loader. This should be corrected before merge; the accompanying libdragon revision change also requires explicit owner review because its compatibility and security impact is not verified.

Restore Neo Geo ROM detection.

Within view_load_emulator_init, the only branch that assigns CART_LOAD_EMU_TYPE_SNK_NEO_GEO is commented out. Matching Neo Geo files therefore fall through to later checks or show "Unsupported ROM". The new neogeo loader configuration cannot be selected from this screen.

Restore the active else if branch.

I am still wary of this change.

It might be just me, but when I first implemented it, I thought long and hard about the different uses of the expansion pak against all the released games.

To me, not used means that a game may fail to work when an expansion pak is present.

I guess I am okay with enhanced but it needs a bit more thought (given the different ways that games may use it), like some just add a hi res mode, but some unlock new features.

That’s a good point. What if instead of treating every optional Expansion Pak enhancement as the same generic case, we add a few additional flags to the existing ROM feature bitmask describing what the Expansion Pak actually adds?

For example, something along the lines of resolution, frame rate, and additional content/features, etc.

Then the info screen could display something like:

Enhanced - Higher Resolution

or

Enhanced - Higher Resolution, Additional Content

depending on the game.

That would keep Required/Recommended describing the game’s memory requirement, while Enhanced could actually tell the user what installing an Expansion Pak changes?

I definitely think there's value to show the user what they get when they use an expansion pak.
