Retro Game Asset Studio

Introduction

This application allows the creation of various asset types (graphics, sound/music, levels) for retro game platforms (currently Amstrad CPC, ZX Spectrum and Commodore 64). It is a cross development tool in that it will run on a PC and produce output to be consumed by a compiler (such as WinAPE for the PC or MAXAM on the CPC).

It is free and open source. It is also a work in progress so some features may be incomplete and/or buggy.

This application is an evolution of the AMSprite program, which will no longer be developed as all its features have been moved to RGAS.

Features

• Uses a common editor for all target platforms.
• View sprite animation preview at any frame rate
• Edit hardware sprites for CPCPlus, with custom palette
• Export to multiple languages per platform. (e.g. 3 targets are supported for CPC: MAXAM assembler, C, and Basic).
• Import any image file and convert to bitmap with fine control over brightness, contrast and dithering. Includes palette optimisation.
• Import any video file and generate an assembly program to replicate (CPC only).
• Export a blank image with indexed amstrad palette for editing in external paint program. Can be reimported.
• Includes a full test program to see your sprites in action (CPC only).
• Includes a basic level editor
• Includes a basic sound effects / music tracker (CPC only).
• Cross Platform, run under Windows or Mac/Linux via MONO runtime (excludes video import for CPC).
• Runs under Windows RT with jailbreak applied.
• Edit multiple sprites simultaneously in a grid (custom grid columns, any combination of sprites).
• Onion skinning in sprite editor of either other sprites or any image file.
• Editor supports standard bitmap editing conventions such as Ctrl+Mouse wheel for zoom etc.
• Handles attribute blocks for Spectrum/C64 bitmaps.
• Sprite rotation.
