Whether you are a longtime fan of the series or a newcomer looking for a fast-paced RPG experience, the CODEX release represents a definitive way to play this pivotal chapter in the Ys saga. The Evolution of Ys SEVEN

: Players can swap between three active party members on the fly. Each character possesses specific damage types—Slash, Strike, or Pierce—requiring strategic switching to exploit enemy weaknesses.

The CODEX release of Ys SEVEN provides several technical advantages over the original 2009 handheld version:

DLE 2.1 replaced DLE 2.0 by compressing the software to fit onto 3 EPROMs instead of 4, and by allowing the diagnostics ROM check to pass if other game EPROMs remain in the unused sockets, and by correcting a bug with one of the death scenes.

The 2.x series of DLE resequences the game to keep similarly-themed scenes in sections. Reversible scenes only need to be completed once during one game. The DLE 2.x scene sequencing chart provides a thorough explanation.

The 2.x prototype mode plays over eight minutes of cutting room floor animation that was added to the limited edition laserdisc, with the original experimental design concepts of multiple branching and the "ACTION" button that were present in the prototype Dragon's Lair arcade game.
(The original Dragon's Lair laserdisc works with the standard game mode. The limited edition disc is not required.)

DLE 2.1 is a 3 EPROM set that works with any working Cinematronics Dragon's Lair game using any laserdisc player or video source.
Dragon's Lair uses type 2764 or 27C64 EPROMs or compatible, rated 250ns or faster (2764-25).
EPROMs rated slower, such as 300ns and higher (2764-30), have been reported incompatible.*
National Semiconductor brand EPROMs have been reported incompatible.*
*(These are original hardware incompatibilities, not specific to this ROM.)
