MegaROMs on fMSX and Konami cheats.

[Anonymous]

Hi all, 

Having a few problems running the MegaROMS in fMSX (dos ver.).  Am I
missing one of the supplimentary ROMs need to run these? (such as MSX.ROM)
And, are there any cheats for Konami games (mainly shooters) that are
related to the ones on the NES (u,u,d,d,l,r,l,r ab start) or others?

Just curious, and

Thanks!
