SEGA Master System 60Hz mod

Repair Service

(Master System 1 only)

We don't support the Master System 2 as that console doesn't have a rear video output DIN socket. You need this DIN socket for RGB.

This is a repair service for the SEGA PAL Master System 1 console. The console runs at 50hz by default, this mod allows it to run a full speed at 60hz like USA consoles.

By default the PAL video standard runs at 50Hz and NTSC at 60Hz. This makes games play noticeably slower. Once you've experienced playing games at 60Hz you'll find it hard to go back... This service allows you to mod your slow PAL SEGA Master System 1 into 60Hz and enjoy these games at full speed and from other regions.

Technical

This mod will force the console into 60Hz which can be controlled via a switch we install on the rear of the console. If you don't want this switch installed and prefer it to always remain in 60Hz, then please contact us at the time of ordering.

NOTE: Video Output issues

Once the console is switched into 60Hz, the colour will be lost if you're using basic composite video cables. (This is because the internal crystal is set to an unsupported speed and your TV wont understand it). Another way of understanding this is if you have a PAL console and we force it to boot NTSC games at 60hz, you will get black n white video image. RGB is the best way around this problem.

We strongly recommend using RGB cables such as RGB SCART into an OSSC or RetroTink or buying a 3rd party HDMI adapter.  This gets around the issue as RGB is unaffected but the speed we set the console to.
