I already said as much on NintendoAge, but thanks so much for this! I'm already up to Round 2, it's been pretty interesting so far.
I loved the US NES version of this when I was a kid, and ever since ive heard about the japanese version ive always wanted to play it. Cant express my gratitude to you enough mrmark for making this an actual possibility!
I don't mean to make a big stink but, I ran this rom on jnes and it worked fine. Which is a little odd since Jnes only has support for ntsc U.S. roms and it can't play famicom roms. So this is either a simple graphics hack to look like the famicom proto or this is a nes proto cart with the more morbid setting before it was changed.
NES and Famicom hardware are virtually the same, programming wise. They're both NTSC and run at the same clock rate... they differ only on hardware like the Famicom mic controller and the extra pins for sound mixing in the cart connector.
Do you mean the Windows or Android emulator? I don't know why the jnes name resurfaced on a completely different platform years later. Anyway the Android one allows Famicom. "• NES NTSC (US, Japan) and PAL (Europe) region support" https://play.google.com/store/apps/details?id=com.jabosoft.jnes
I'm talking about the windows version, I admit the version I am using isn't the most recent release. I really haven't tried many famicom games with it, just some pirate bootlegs which might be why they don't work. It can actually run a few famicom pirates, a ripoff of Link's Awakening, and Super Donkey Kong 2. I will see if it can run commercial famicom roms and if the updated version has famicom support now.
It's impossible for an emulator to lack basic famicom support. Early games like Super Mario Bros are identical to USA. But it could be missing famicom specific features. such as famicom disk system, controller 2 microphone, japan only mappers and enhancement chips...
