I hope it's not uncool to ask, but I was wondering what cartridge board Project Blue uses?  I'm really loving the game, the bonuses with the digital edition, etc.

Thanks!

There are both BNROM and GTROM versions depending on region, but the digital release is BNROM.

Thanks toggleswitch, I appreciate it.

Do you where can I purchase a home brew BNROM, or GTROM, PCB?

Hi Adam, 

I'm not sure if GTROM is available in small quantities, there is no webstore for them that I am aware of. 

You can get a BNROM PCB from InfiniteNESLives, I think they're like $12 or so.
