Please, note that the game was released in cartridge in 2010 (out of stock now). Check Paxanga's web for details.
Hi, nope,as said at the manual. It lacks option file saving on the same cartridge (cause non-sense on a ROM file and dangerous in case you burn it on a flashcart), and the Cheat Engine, that anyway nobody uses (and still you need a 2nd game to use it). Other than that, it's the same. You have all levels, all options, the extra game...
