i have same same game, but Original release, v1.003
is it Editions, versions or Alt in dat?

[Rocknroms]

version, it's always been like this. Moreover from no-intro convention so we avoid anything else

3.5 Version
Optional
This flag shows the version (vX.XX) or revision (Rev X) of the game. It is put in
parentheses. Revision is used instead of version when applicable. Numbers
and/or letters can be used depending on the system or program approach.
The flag is only added if the version/revision is greater than the initial release.
Source is usually ROM header or cartridge stamps.

It says ROM header and not only cartridge stamp, so we have disc header to determine version.
ALT is used if we have save version, same release, same everything but different crc.

ok then, thank you very much, Rocknroms

but it's not always like this in db, for example Sega Saturn Grandia Limited Edition is Alt
so i asked

[Rocknroms]

Sega Saturn Grandia Limited Edition is Alt

This is not confirmed. My dump was "limited" because I got the bonus stuff sega used for some limited that are 1=1 like the original, even same serial (you got bonus stuff and they call limited releases, DC has many of this releases, last one was Trigger Heart Exelica that come with a bonus poster)... so probably we have to rename it to Original but it's better to wait unless some other news.
