It's a shame you can't multiboot these games to other GBAs, I think Eurasia should of included an option for that in the menu or left the games as they were and not included them as a bundle. Still this is pretty cool although the NES roms run very badly on VBA; need to try it on my flash cart.
Re: Costello this is not a commercial rom and so far all multiboot, beta and PD roms have not been included in the release list, so I don't think this should be numbered.
The rom is only 6mbit because they are simply a collection of multiboot games. All multiboot games are under 256kb each, they are designed to be played on the GBAs ram, not on a cart so hence the small size.
p.s Thanks shaunj66 for sending me them on irc
BTW Octavious, yes these are the full games minus any multiplayer modes that were in the original NES versions.
