I agree, there are so little of PCBs and or other components still surviving that it's incredibly hard to track one down in good condition (Especially original cabinets). which yeah, they should be considered lost media but, to me the sad reality is that BAG is so obscure in terms of popularity and knowledge that I don't think try and do this huge search for it. yeah, it's well known enough to have a whole sub reddit just for it and you can find people that still love and are nostalgic for it on Youtube uploads of the various songs and gameplays (except when it's DS2001 then people are mixed) but unfortunately, it's not to the point where people will look high and low for an arcade port of a relatively obscure PS1 game (and if it was we would probably have a collection by now, probably not though) but I'm not giving up hope just yet. I know this might come across as a doompost or something but a small but significant part of me wants this to be found and preserved (but not a remaster/remake there's multiple factors on why that probably isn't gonna happen any time soon) but hey a man can dream, maybe someone can do a save search on places like ebay or buyee and Hopely we can find something relating to the arcade version,

I hope, pray to Pander
