Famicom Expansion Audio Carts - Best Examples

During the Famicom's lifespan, 26 cartridge games were known to support expansion audio.  The Famicom directed its audio to cartridge port and games that did not use expansion audio would simply loop it back to the RF modulator.  The expansion audio that these 26 games would generate would intercept the internal audio and mix it with the expansion audio and send the combined signal to the RF modulator.  In addition, 75 Famicom Disk System games (4 of them unlicensed) are also known to use expansion audio generated in the FDS RAM Adapter.

Here is a list of all Famicom games known to use Expansion Audio : http://wiki.nesdev.com/w/index.php/List_of_games_with_expansion_audio

In this post, I identify the most accessible games for English speakers using each expansion audio chip and describe what needs to be done to play it.

Sunsoft 5B




Gimmick! - The original cart alone can go for $200 easily, however, there is at least one other more common Famicom cart (Gremlins 2) with a Sunsoft 5B chip, but obtaining one is something of the luck of the draw.  Additionally, one can make a donor NES cart with a Batman Return of the Joker and an AY-3-891x chip, or you can get a INL-ROM NES reproduction board with an AY chip on it.

Konami VRC-VII



Lagrange Point - This is the only game that uses the expansion sound capabilities found in this chip, which is exclusive to this game and Tiny Toons 2 Japanese version.  Tiny Toons 2 does not have an SRAM chip, battery or any of the passive components to mix the audio, so it would be a large undertaking to get it to work in a NES cart.  I am not sure whether the Largange Point board plus a pin converter would fit inside a NES cartridge shell because the game's board is very tall.  You may need an external pin converter.  Interest in this game has also increased substantially because of a full translation patch.

Nintendo MMC5



Just Breed - This is a large strategy RGB from Enix and one of the three games that use the expansion audio of the MMC5.  Because of its translation patch, it is by far the most accessible of those games.  The original cartridge can have its ROM replaced with a translated ROM burned onto an EPROM, some minor reworking will be required.  Because it uses Nintendo's MMC5 board, this can work with a reproduction cart in a NES.  The most suitable NES cart is Gemfire, but I suspect that any of the battery backed MMC5 boards will work with some minor reworking. Castlevania III and Laser Invasion will require the addition of an SRAM chip and a battery, not a beginner mod.

Konami VRC-VI



Akumajou Densetsu - This is the Japanese version of Castlevania III, and does not have so much Japanese text that it requires a ROM swap to enjoy it.  The Famicom board is small enough to fit inside a NES cartridge shell with a converter without difficulty.  Madara and Esper Dream 2, the other games that use the chip, do have translation patches.

Namcot 109/163



Rolling Thunder - Most Namcot 109/163 games with expansion sound are not very English friendly.  This game is basically the NES Tengen version with better sound.  Additionally, Namcot almost always used epoxy-bonded ROMs on their boards because they were cheap.  Unfortunately, this makes replacing these ROMs with translated ROMs on EPROMs very, very difficult.

NEC µPD7755C/µPD7756C & Mitsubishi M50805



The NEC ADPCM Speech chip was found in Jaleco's Japanese baseball games, virtually all of which were ported to the NES in the Bases Loaded series.  The chip stored and could play back voice samples on command.  Grab any one of them, games like Moero!! Pro Yakyuu are as common as they get in Japan, but realize its only a novelty.  Of course, the speech samples are in Japanese for the Famicom cartridge and English for Bases Loaded.  The NES versions had more PRG-ROM space to store the samples in ROM instead of on a special chip and used the NES's internal PCM channel to play them.  The Mitsubishi chip was found in Family Trainer 3: Aerobics Studio, which was similarly ported to the NES as Aerobics Studio.  Roll out your Power Pad for that one.
