Ultimate RPG Bot begins

Two learned statue tasks and a real save round trip form the next step toward a bot that can play Seiken Densetsu 3.

What you can try

Open your adventure file, resume the game and find Ultimate RPG Bot below the game controls. Choose a learned task and follow its starting instructions. The first task faces the Beast Kingdom gold statue and starts HP/MP restoration. The second selects No at its save question. Both use Kevin’s opening checkpoint.

Watch bot play replays a demonstration with screen checks. Pause bot stops and pauses. Take over releases its buttons and returns control. Training lets you record short actions, label worked or failed attempts, resume an unfinished demonstration and export experience.

Experience files contain screenshot features and inputs. They remain separate from adventure files and the manual story checklist.

The save test

A genuine level-1 save revealed that the old validator read the game’s zero-based level as an invalid level zero. Native menus also initialize fields in otherwise empty slots. These specific cases are now recognized while checksum and unsupported-record checks remain.

The repaired local candidate completed a real statue save, downloaded it through the website’s Save button, matched all 8,192 bytes against the native export, closed the page, reopened the downloaded file and loaded Kevin at the Beast Kingdom statue. The new slot showed 0:55:04, level 1, HP 90/90 and MP 6/6. No cheats or snapshot loads were used.

Direct overwrite of the same chosen OS file remains unverified. In download mode, keep the newest download and choose that file on your next visit.

Training results and next steps

The statue task completed two independent local native-game replays; the decline task completed one. A moving NPC blocked an earlier attempt, which was labelled failed. Wrong dialogue and an already-selected No stopped playback before action 1. Active Pause and Take over were checked during a running action.

This is a small demonstration-based prototype. It cannot yet find arbitrary destinations, handle combat, manage inventory or play the entire story. Navigation, battle practice and longer independently verified routes are next. Reusable experience records and a separate game adapter are the foundation for future games.
