Paco Menéndez (programming) and Juan Delcán (graphics), 1987. Distributed by Míster Chip and, from 1989, owned by Opera Soft.

Text, design, own screenshots, and the Atari 2600 demake: Juan Sánchez Jurado. A non-profit tribute, not affiliated with the game's rights holders.

The Atari 2600 demake is by Juan Sánchez Jurado, with help from Claude Code. Its English texts come from the translation made by the community for the Amstrad CPC version.

The own ZX Spectrum screenshots and the audio tracks were made with the project's own emulator and tools; the Atari 2600 ones, with the Stella emulator.

The emulator on the Play page is Stella 7.0 itself (Bradford W. Mott, Stephen Anthony and the Stella team; ELF emulation by Christian Speckner) compiled to WebAssembly, under the GPL version 2 or later; the complete source code and the license can be downloaded from that page.

The headings use Papiro Abadía, a typeface made for this website from the letters of the game's parchment, the calligraphy in which the introduction and the ending are written. The original does not store those letters as drawings but as strokes: the list of points the pen paints, one by one. They were extracted from the Spanish and English versions, and the missing ones were drawn by hand in the same style: the capitals K, N, Q, R, U, V, X and Z, the digits 4, 5, 8 and 9, the accents and a set of small capitals. Then they were vectorized: each letter is enlarged with Scale2x, which turns the staircases of the diagonals into clean lines, and traced into curves with potrace. The parchment's ornate capitals are used for the game's name and the first letter of each heading; the other capitals, in small capitals, because a whole word in ornate capitals cannot be read.

The text is set in Cormorant Garamond; the notes and menus, in IM Fell English SC; and the "2600", in Urbanist. All three are under the SIL Open Font License and served by Google Fonts.

To those who have preserved and documented the abbey for forty years: Manuel Abadía, for his analysis of the original code; Antonio Giner and Manuel Pazos, for being the first to disassemble the game and reveal all its secrets to us, and for their versions; Pazos, also, for his map; and to Computer Emuzone, MSXBlog, El Mundo del Spectrum, Spectrum Computing, CPCWiki, and the Internet Archive, without whose archives this website would not exist.

For the demake, to Wolfgang Stubig (Al_Nafuur on AtariAge), creator of the PlusCart, and to Zackary Scolaro (ZackAttack on AtariAge), creator of the Chameleon Cart, for their invaluable help in getting the game to run on their cartridges. And to Darrell Spice Jr. (SpiceWare on AtariAge), for the ideas for creating 128-pixel-wide graphics, with the bus stuffing demos shared on AtariAge.
