Adventure Game Builder 5.2e for FM77AV

Adventure Game Builder for FM77AV/XM7

This software is a Windows application for creating nostalgic text-input adventure games that can be played on Fujitsu FM77AV20/40 systems or on the XM7 emulator.　English Version

In this new release, games can run on both the actual FM77AV hardware and the XM7 emulator.

The generated .D77 files can be written to physical floppy disks for use on real hardware, or used directly in XM7.

【Features】

【High-Quality Graphics】

You can directly use 320×200 pixel, 24-bit bitmap images as your source artwork.

The system automatically selects the optimal 64 colors from the 4096-color palette based on each image.

Rendering speed on real hardware is approximately 7–8 seconds per screen.

【Scenario Creation】

A simple text-based editor is included.

During editing, scenes and images can be linked and visually previewed.

【Keyword Matching】

Player commands can be checked using either “Exact Match” or “Fuzzy Match” modes.

【Game Capacity】

The upper limit is whichever of the following is reached first:

A maximum of 255 floppy disks can be used

→ allowing for approximately 3,500 images in total.

Each scenario has a limit of approximately 15 KB, but up to 255 scenarios can be chained together.

While the only sound effects are simple “beeps pipipi” accompanying message displays, I hope you will enjoy the nostalgic atmosphere of the early 1980s that this system is designed to evoke.
