NgpCraft Emulator v2.9 is released. A Neo Geo Pocket / Neo Geo Pocket Color emulator: a fast native C++ core (TLCS-900H + Z80 + K2GE video) driven by a PyQt6 desktop shell. Its timing is calibrated against real hardware — instruction-fetch wait-states on the cartridge flash, silicon-measured MUL/DIV and LDIR costs — so self-timed games (Cool Boarders Pocket, Densha de Go) run at their true 30 fps instead of the ~2× too fast that most emulators show.

Features:
Library with cover thumbnails (grid / list / compact), live-reflowing — plus search, sort (name, last played, most played, playtime, recently added, size, with a direction toggle), favourites ★ and a never-played filter. Play count, playtime and last-played are tracked per game.
Console boot — with a real BIOS, Boot BIOS powers the console on for real: the Neo Geo Pocket intro plays and the game then boots on its own, exactly like hardware.
Video: integer / fit / stretch scaling, scanline / LCD-grid / CRT filters, colour profiles, real fullscreen. The canvas follows the window; size presets Ctrl+1…5.
Black-and-white cartridges, in colour — an NGP game on an NGPC is colourised, the way a Game Boy game is on a Game Boy Color. Both machines are selectable — see Monochrome cartridges.
Save states — 8 slots per game (toolbar or F2 save / F4 load / F3 slot).
In-game saves — the game's own flash save, stored in the ROM, a separate file, or both.
A console that remembers — the coin cell keeps its BIOS settings and its clock, so the date is still right next time. The RTC alarm works too, and goes off on time.
Speed control — fast-forward (hold Tab) and 0.25×…4× ([ / ] or the toolbar).
Rewind — hold , (or the ⏪ toolbar button) to run the game backward; release to resume. . steps one frame forward. Buffer length configurable (Off / 10 / 20 / 30 s).
Screenshots (F12, folder configurable), FPS overlay, a hideable player toolbar.
Controller support — an Xbox-style (XInput) pad alongside the keyboard, plus turbo / autofire on A and B at 5–20 presses per second.
Fully remappable — console buttons and every in-game hotkey, with a warning when a binding would collide. The console buttons are bound on a picture of the console: each field sits next to the button it drives, so you pick the D-pad's left rather than a row labelled "Left".
Themes — follows your desktop's light/dark setting by default, or pick Light or Dark explicitly. Switches live, no restart.
Debug tools (F1) — a real debugger: symbols, instruction stepping, call stack, raster event timeline, read and write watchpoints, an editable hex view with access highlighting, RAM search, and audio analysis with VGM export. See Debugging.
ROM analysis — right-click a game to boot it, drive it, and report what is wrong with it. See ROM analysis.
Crash reports — a ROM fault writes a detailed crashes/*.txt (reason, PC, opcode, registers, memory & stack dumps).
Translated interface — English and French, switchable live, no restart. One JSON file per language in lang/, so adding one is adding a file and needs no code: see TRANSLATING.md. Contributions welcome.

NgpCraft Changelog:
Online play has been reworked. There is now a second mode that runs the game on both machines and sends only the button presses, so game speed no longer depends on your ping, and the two PCs swap cartridges when a session starts, so you no longer need the same file as your opponent. Losing a connection no longer takes the emulator down. Online is a hard thing to get right, so treat this as a real improvement that still needs to prove itself in actual play, and keep the reports coming.
Two players on one PC now get two windows of the same size, side by side instead of one on top of the other, with an optional single-window mode.
An archive holding several games now lists all of them, each with its own save and cover, instead of loading one at random with a shared save.
Fixed: analysing a compressed ROM, LINK ERROR in The Last Blade, Puyo Pop, Samura Shodown 2, the glitched line above the special bar in SNK Gals' Fighters, the black screen when booting a monochrome BIOS, and the generic taskbar icon on some Windows 11 PCs.
Still on the list: Dark Arms link
A big thank you to ameliandev and davidvaldivia87 for testing and providing detailed feedback on the link function.
