When it comes to the six original Mega Man games there is a clear dividing line between the first three and the last. Mega Man 4 introduced the charging shot mechanic that allowed players to hold down the fire button in order to power-up a single blast from Mega Man’s arm cannon. The aptly named, “Mega Man 4: Free of Charge” ROM hack by [Peter] seeks to bring cohesion with the first trilogy of Mega Man games by removing the charge shot mechanic completely. To compensate for the change, enemy health bars were also adjusted so that enemies aren’t as bullet-spongy.
The Mega Man 4: Free of Charge download comes as an IPS patch file. There are free utilities out there like Floating IPS that can apply the patch file to a clean dump of a NES cartridge. This ROM hack is playable on original Nintendo Entertainment System hardware via a flashcart device, or it can be played by any common NES emulator like FCEUX or Nestopia.
One of the most annoying parts of Mega Man 4 (minus the difficulty) was the constant whir of the charge shot drowning out the brilliant soundtrack. With a patch like [Peter]’s this is no longer a going concern, and players are able to give their thumbs a bit of a break by not needing to continually hold down fire throughout a run. All welcomed changes aside, it still won’t change the fact that the Japanese TV commercial for the game is cooler than the print ads in the US.
