Then open 'Contents' and drop Disksys.ROM into the MacOS folder. To do that, control-click MacFC and 'Show Package Contents'. In order to use the FDS functionality of MacFC, you need to obtain Disksys.ROM and place it inside the MacFC application. I have converted all Japanese text inside the actual MacFC application to English, but I left the documentation that comes with MacFC in Japanese because I am unable to accurately convert that much text.

MacFC can no longer easily be launched in Mac OS 9 (or earlier) or the Classic environment (Use the Classic Version of MacFC in Classic.).

Icons can show if the ROM or disk image is compressed if they have the appropriate filename extension.

I personally remade the bundle for MacFC.

Native gamepad support in Mac OS X (You'll need GamePad Companion or something.).

Direct Game Genie Code support (you could still 'burn' codes into your ROMs to use them).

Custom video filters, such as HQ2X or 2xSAI.

Different frame skip options for each level of zoom.

User-adjustable application priority level.

High-speed disk access option (and variable speed increments) for FDS/FAM images.OSD options (meters, messages, etc.), each can be enabled/disabled.

ROM / FDS image info shows various technical info.

Icons show whether a ROM or disk image is compressed or not (like Power64 and Nestopia Bundle Tune-up).

Enable/disable each sound channel, and each extended sound channel (total 13).

Very accurate Famicom Disk System if you want to play FDS games.

Runs many hacked games that will not run in other emulators.

Emulates a light gun with the mouse and cross-hairs.

Runs full-speed on any Mac OS X 10.3.9+ machine.

Here are some features that make it stand out: MacFC is different than other Mac NES emulators, such as RockNES and Nestopia. If you want the Classic Mac OS Version, please go to this page. MacFC is a Japanese Nintendo NES / Famicom emulator developed by T.Aoyama.
