Le Manoir du Dr Genius returns, in isometric view
Loriciels' 1984 Oric adventure is reborn on the Neo6502 as an isometric point-and-click game, played with the mouse. A public beta is on Prophet.
Le Manoir du Dr Genius is an adventure published by Loriciels in 1984 on the Oric. You try to escape the mansion of the late doctor, between a monster lurking in a cupboard, a dwarf and lightning. Its new edition for the Neo6502, MDG-NG, has been in public beta on prophet.3617.fr since 5 November, in the "in development" category. It is an unofficial port: the game, its texts, graphics and music belong to their rights holders.

1. The same game, another way to play it
The original was played by typing commands. Here you click the floor and the hero, an explorer in a top hat, walks to that spot, going round the furniture. You pick a verb in the bottom bar (the interface is in French: Regard, Prendre, Poser, Ouvrir, Allumer, Agir, Attend, Sentir), then the object. Objects are dragged into or out of the bag; dropping the key on a cupboard opens it.
The game has 25 illustrated rooms, 18 objects and 11 full-screen scenes: nine deaths, the dwarf's chase and the victory. The original's three tunes are there: the Badinerie at start-up, the Sarabande after a death, Tea for Two at the victory. As in 1984, chance is cruel: the game starts over after a death.
2. Faithful to the original rules
The starting point is our C rewrite of the Oric BASIC program, which served as the specification. MDG-NG's scripts are generated from those rules, then compared with the C engine over 14,000 commands, with no divergence. A 63-command winning game is replayed with the mouse in the emulator, from the start to the victory scene, checking the room and the bag on screen after each command.
3. ADORE, an engine for other adventures
MDG-NG runs on ADORE, our adventure engine in 65C02 assembly: hero walking, depth masks to pass behind furniture, drag and drop, music. It is also the engine of our edition of L'Aigle d'Or, published on Prophet. The code of the engine and of the game's tools is under the EUPL 1.2; that licence does not cover the game's content.
4. What we do not claim
This is a beta, tried in the Phosphoneo emulator and not yet validated on the real board: reading a game file of more than 2 MB, the pace of the effects and the walking may behave differently there. The room and scene pictures were produced by image generation from our templates, then converted to the Neo6502 palette; they do not reuse the 1984 drawings. The code has no public repository yet.
