Hi,

Continuing the trend, this time with that other NES Mario game.

Hard Rock Miner Lv. 1
OLTOTO
ISNEGVOK

NOTE: Dig holes anywhere and pull up bombs. The bombs will destroy any part of the landscape. Invincibility recommended.

Hard Rock Miner Lv. 2
OLTOTO
ISNEGVOK
TEUPPAIV
NOTE: Dig holes anywhere and pull up bob-ombs, which detonate quickly. The bob-ombs will destroy any part of the landscape. Invincibility highly recommended.

Dig up mushroom blocks anywhere
OLTOTO
SXLPAE
NOTE: Dig holes anywhere and pull up mushroom blocks. The surface you pick up will determine the block you drop (try this with pots; you can still go down them). You can't drop blocks in front of background objects.

PRG1 means program revision 1. Well how do I know if those codes will work on my real cartridge of SMB2 and/or a SMB2 ROM? How do you find out what program revision a SMB2 ROM is? How do you find out what program revision a real cartridge of SMB2 is?
