I still have my box set that came with 1-3 plus the Arena, a pocket watch, some joy stick covers and I think memory card case for the PSone. I think it came with a few other little things too, but can't remember what.

Arc the Lad Collection CodeBreaker/Gameshark Codes (NTSC-U) This page contains CodeBreaker/Gameshark cheat codes for Arc the Lad Collection (NTSC-U) for the Playstation 1. Depending on if you're playing this game on a physical console or an emulator will determine how you use the codes found on this page.

Don't feel like digging it out right now. Was a fun game though. Not sure how well a port would go, again with cost. Emulators are free, just need a hard copy or ISO image, I keep images of mine after wearing out a copy of Diablo.Don't know if GOG could come up with their own 'console emulation station' and get permission to sell image files or not. Slugterra dark waters new arena. Would be interesting to say the least. But so many games are being remade in HD or in other forms, I think getting the rights would be tough.

Resident Evil for example.
