Retro Arcade Sprite Sheet Extraction

Yes, You can use AI, but the results must still be of quality.

I have the original arcade-grade files for a classic Japanese cabinet 'Janken Game Acchi Muite Hoi!' and need every single graphic asset pulled from it. That means characters, enemies, UI elements, background props, effects—absolutely everything that ever appears on screen.

You’ll be working directly from the ROM files, so familiarity with MAME, tile viewers, and palette-accurate extraction tools (Tile Layer Pro, YY-CHR, Aseprite, etc.) is a must. I’m expecting clean, artifact-free PNG sprite sheets, each one grouped by the individual character or object it belongs to. Please preserve native resolution and original palettes; no resizing or recolouring unless a clear transparency fix is required.

Deliverables
• One sprite sheet per character, enemy, UI element, stage prop, and effect, saved as PNG with transparent background
• A simple index (TXT or CSV) listing sheet file names, frame counts, and animation order where obvious
• Any custom scripts or batch files you wrote to automate extraction, so the process can be repeated if needed

Acceptance criteria
• Every visual asset in the game is present and correctly coloured
• No tile gaps, duplicate frames, or unwanted emulator overlays
• Sheets open in Aseprite/Photoshop with transparency intact and a consistent grid

Let me know your workflow and how long a full rip like this usually takes you, and we can get started right away.
