This is accomplished by either using a Mega Everdrive Pro, or Mega SD ROM Cart, or by using any way to load a Genesis rom, plus a CD in an actual Sega CD console allowing for 100% compatibility on real hardware!Īlex started with Castle Of Illusion Staring Mickey Mouse, which replaced the game’s audio with music from the 2013 remake! He’s also working on a patch for Quack Shot that integrates the Sega Saturn Disney Collection soundtrack, as well as a version of Chiki Chiki Boys (Mega Twins) that uses the PC Engine CD soundtrack, as well as a few more (listed below).Īnother patch that’s also in progress ads the arcade soundtrack to Street Fighter II Remastered Edition. Doing this for every rom hack that doesn't work would result in tons of new DB entries, and probably tons of hacks in Mesen's code, so it's not really something I want to do - at that point it'd be more about emulating FCEUX's behavior (and in even older hacks, maybe even Nesticle's!), rather than emulating the NES' behavior.Alex aka ArcadeTV has begun using Krikzz’ MSU-MD driver to add CD quality audio to Sega Genesis games. There is a way to use up to 512kb of PRG ROM on some MMC1 carts, but that works differently than what this hack is trying to do.īasically, the hack is broken and would never work on a real MMC1 cartridge - there is unfortunately not much I can do here, any solution would require me adding hacks to Mesen's code to support this and then add the rom hacks to the built-in game database to try to detect them and enable the behavior the hack expects.

In FCEUX, this used to work, but on hardware, this actually doesn't work - that bit is actually a flag to enable/disable the save ram. It does work in 2.2.2, but not in 2.2.3 - it looks like support for this 'hack' got removed by this commit: Įssentially, the rom hacks try to use more than 256kb of PRG ROM using the 5th bit of register $E000.
