[neogeohunter]

Hi guys! ...just curious, what so special about the "GRADIUS Bubble System Version"? Price is going crazy on yahoo auctions: https://buyee.jp/item/yahoo/auction/u416325986
Thanks for any info!

It's just rare, especially in fully working condition. It seems to have been recapped, so I'm sure someone puts value on that too.

seem to remember the last few that went for sale nearing 2k . another unique collectable dont remember ever seen one that wasnt gradius

I think the Japanese ROM version sold for 1,000,000yen a while back too.

I own a Gradius cartridge and it has to be one of my favourite arcade related items due to the funky design and obscure history of bubble memory technology.

The Konami design, it's quite bonkers when you read into it.

The bubble system was relatively inexpensive about ten years ago until a solution to revive non working pcbs became available.

Unlikely I will be able to find a motherboard to play it on these days..

i saw a working one on yahoo with what looks like some fpga replacement inside the bubble cart case? is this the solution?

[nem]

That's one solution, yes.

There's also this that was in the works:

Not sure if @ikamusume ever got it working?

Looks like the same thing as he talks about his first fpga project?

I not long just covered this version in one of my videos. Maybe I drove the price up!
