UX Suggestion (Show more info about ROM)

[Theone5000]

UX Suggestion:
When input GBA rom display (next to MD5 checksum):

• Region (USA/EU/JP) etc.
• Rom version (V1.0/V1.1) etc.
• Official rom ID

This is a problem because require a database with this information where I can get this information.
I don't know if there are some APIs online for this as example that based on the checksum or the filename give this information.
The rom header don't have this information...

I don't know about the API's out there. Can't really imagine that there aren't any. This is what I could find:
http://offlinelistgba.free.fr/index.php Nonetheless it's good to know that the ROM header does not have any additional info.
Looking foreward to more of your work. This program looks very promising,

The rom header just include a codename, that can change between various regions but can be the same between dumps.

Retroarch to get info by a rom use a database copied from https://datomatic.no-intro.org/index.php?page=search
From here it is possible to search for a hash and get info about the rom but doesn't have any API, require to download a db file and read from there

Retroarch keep also a db of homebrews and hacks:

• https://github.com/libretro/libretro-database/blob/b4e0a4e3bcf5c319147a7785d8623d02d0c5e99f/metadat/hacks/Nintendo%20-%20Game%20Boy%20Advance.dat
• https://github.com/libretro/libretro-database/blob/44cd26daa00e4164841775e342ed526be5573d90/metadat/homebrew/Nintendo%20-%20Game%20Boy%20Advance.dat

I think that the best option is add a button that open datomatic to the search page where the user inserts the hash in the search page.
