PLAY NOTE
Why two revisions of the same game deserve clear labels
A catalog note on ROM revisions, duplicate-looking entries, and why filenames alone are not useful to players.

Same title does not mean same file
Publishers sometimes released corrected or region-specific revisions without changing the title on the box. Two entries can therefore look identical while containing small code differences. A catalog should label that relationship instead of presenting each file as a separate game.
Filenames are operational clues
Tags such as PRG0 and PRG1 help maintainers distinguish files, but they are not a friendly explanation. The game page should name the revision and point alternate versions toward one canonical entry so search engines and readers understand the duplication.
Do not invent a difference
A revision label proves that files differ; it does not automatically explain how. Unless a change has been verified, the responsible description is narrow: earlier revision, later revision, or alternate release. Guessing at bug fixes creates bad metadata that spreads easily.
One page should lead
A canonical entry gathers the general description and discovery signals, while the alternate remains available for users who need that exact revision. This keeps the catalog honest without hiding a legitimate distinction.
