Darksoft STV Multigame Kit | Dark Knight Edition

The kit includes the Darksoft ST-V Dark Knight Edition multigame PCB, traditional LCD selector, selector connection hardware, and the supplied installation wiring/components shown in the current installation guide. A compatible SDHC microSD card is required and is not included.

The optional reset connection allows the Sega ST-V system to restart automatically after a different game is written.

• One supplied DuPont wire is soldered to Pin 8 of IC12 on the original ST-V motherboard.
• The opposite end connects to the multigame board's reset connection.
• Without this optional wire, power-cycle the ST-V after loading a new game.

Pin 8 of IC12 can be damaged by excessive heat. This connection should be completed only by someone experienced with precise PCB soldering.

A second optional wire can play customized sounds through JAMMA audio when game programming begins and ends.

• The wire is soldered to Pin 13 of the motherboard audio amplifier.
• The opposite end connects to the multigame board's audio connection.
• Optional start.wav and end.wav files are stored in the microSD card's sounds folder.
• These sounds play through JAMMA audio, not through a separate stereo setup that bypasses JAMMA audio.

A region-capable ST-V ModBIOS is not required, but the installation guide recommends it because some supported titles operate only in particular regions.

Installing a ModBIOS requires programming and replacing the motherboard's 27C400 BIOS EPROM and should be performed only by someone familiar with ST-V hardware.

For a supported firmware update, place the update file named flash.img in the root of the prepared microSD card and power on the system.

Do not interrupt power or remove the microSD card while the firmware is being written. Follow the waiting period specified in the installation guide before cycling power.

Review the installation guide and contact HighScoreSaves or the support community before concluding that the multigame kit or another component is defective.

Does the Dark Knight Edition install in the normal ST-V cartridge slot?

No. It installs directly onto four keyed connectors on the original Sega ST-V motherboard.

Is a microSD card included?

No. Supply a genuine SDHC microSD card formatted FAT32. SDXC cards are not supported by the current installation guide.

Can I use an OLED game selector?

Yes. The board supports the included LCD selector and a compatible optional OLED selector. Both can be connected and used together.

Does the selected game remain after power is removed?

Yes. The selected game remains stored in flash until another title is chosen and written.

Is soldering required?

The main multigame board installation does not require soldering. Soldering is required only for the optional auto-reset and JAMMA loading-audio connections.

What happens without the optional auto-reset wire?

The Sega ST-V system must be power-cycled after selecting and writing a different game.

Is a region-capable ModBIOS required?

No. It is optional, but recommended because some supported ST-V titles operate only in specific regions.

Where can I review ST-V compatibility information?
