Hi!
Just wanted to note that KLOV/Arcade Museum/Museum of the Game has completely changed their website, so, while the same data exists, the database format and the web display are completely different.

FIRST:
I found ten games in your database that don't have matching KLOV links.
Game Name***Aurcade Game ID***KLOV Game ID***KLOV Game Slug
Asteroids Recharged***10628***22464***Videogame/asteroids-recharged
Bad Girls***10675***13808***Pinball/bad-girls
chunithm***9466***22484***Arcade/chunithym
crossbeats REV. SUNRISE***3049***22486***Arcade/crossbeats-rev-sunrise
Hammer Champ***8224***22487***Arcade/hammer-champ
Kelley Packard's Golden Cue: Tournament Edition***10683***16216***Pinball/golden-cue
Office Yeo In Cheon Ha***2715***22501***Arcade/office-women-power
Over the Top***2780***22492***Arcade/over-the-top-andamiro
Theatrhythm Final Fantasy: All-Star Carnival***3048***22496***Arcade/theatrhythm-final-fantasy-all-star-carnival
Top Blade V***2682***22497***Arcade/top-blade-v

SECOND:
KLOV's database overhaul introduced game slugs as part of the URL structure.
While
http://www.klov.com/game_detail.php?game_id=6791
still works, you will be redirected to
https://www.arcade-museum.com/Videogame/720-degrees
The game slug (Videogame/720-degrees) is a two-part entity reflecting the new folder structure for games storage (Folder Videogames, File 720-degrees).
Since more than 3000 of your games link to KLOV, I'm wondering if you should do an [ALTER TABLE games_aurcade ADD COLUMN game_slug_klov VARCHAR(80) DEFAULT '' AFTER game_id_klov] to your games database. If you do this, let me know and I will send you the game slugs update table. Then, you'll be able to change the KLOV URL reference to the updated version.

FINALLY:
Nice to see you up and operating again! Zenius-i-vanisher is too confusing to work with and often ventures into Here Be Dragons parts of the world. Plus I hate working with kiddie casino games.
