I'm wondering, if you had someone to re-write eproms, could you use the chd hard drive image and the rom to upgrade a Bemani game? I know they have security usb dongles sometimes, but that could probably be bypassed as well. I haven't really been able to find much about it online. Just curious as I'd love to upgrade my Beatmania arcade game to The Final without paying a ton of money for an upgrade kit that's practically non-existant.
