StarTropics music fix
http://www.romhacking.net/hacks/2229/
>Two of the music tracks in StarTropics are slightly broken, the island map music, and one of the ending tunes. This patch fixes them both.
StarTropics - No Movement Delay
http://www.romhacking.net/hacks/3307/
>This patch removes the 8 frame delay after changing directions and reduces it to 1 frame. You can still change direction without moving by a quick tap of the direction pad.
>The patch only modifies one hex value in the rom. It is a massive improvement over the original game.
>Note: This rom can also be patched with the music fix hack without issue.
Megaman Wily Wars SRAM Save Hack
http://www.romhacking.net/hacks/514/
>This hack enables you to save your game normally with SRAM and you no longer require a special save state to access Wily Tower. The original game used Serial EEPROM which few emulators support. This makes it use the much more common battery backed SRAM method.
> Note that the base ROM used for patching should be in BIN format, not SMD.
Mega Man - The Wily Wars Move-Shoot hack
… was removed from romhacking.net, presumably this is why:
>I started by playing MM2, and the control was much improved by this hack having removed the terrible walk lag. I beat Metal Man as the first stage since he has the weapon you want for most of the game.
>Unfortunately when I got to the next stage, I noticed that the walk lag returned after every time you throw the Metal Blade. It’s even a problem when jumping and then throwing the Metal Blade just before landing!

no you can't download it, I'm just listing it in case it ever gets fixed and reuploaded
also you could just not play megaman 2, assuming you can find a download for the hack somewhere
