Vengeance of Excalibur

×

Vengeance of Excalibur (1991, Synergistic Software / Virgin Games) is the sequel to Spirit of Excalibur, moving the action from post-Arthurian Britain to a re-imagined medieval Spain woven through with Arabian Nights and Arthurian fantasy elements — the demonic Shadowmaster has entrapped the King and stolen the court enchantress Nineve, and the game plays out across seven episodes/scenarios of overhead-map travel, town encounters, and turn-based combat.

This is one of the most thoroughly reverse-engineered games in the middilgard project — every major data format is decoded and cross-verified against the game’s own disassembled loading/rendering code.

What’s been decoded

Area	Status
IMAG (bitmap images)	496/496
FRML (animation sprites)	55/55
Palette system	18 PALT resources, full scene→palette mapping
World map + tile atlas	123×101 tiles, byte-exact Iberian coastline
Entity data	92 unique entities across 7 scenarios
Location data	74 named locations, shared across episodes
Item types	61 items — weapons, armour, spells, treasure
Item placements	130 placements across 7 scenarios
Entity-class bytecode VM	34 classes — same “FSME” VM as Spirit of Excalibur
Scene rendering (SCEN)	266/266 resources, fully traced, zero deviation
Terrain factor/type tables	Confirmed statically compiled in the executable
DOS VGA port	467 IMAG, 51 FRML, same world map — verified end-to-end
