Known issues and quirks

  • Most consoles exhibit some degree of jailbars, but there is a simple mod to fix this.
  • Earlier models of PC Engine, TurboGrafx-16, and Duo systems are prone to capacitor failures. It is recommended to replace the electrolytic capacitors (particularly surface mount ones) on any Duo system.
  • A lot of the earlier consoles seem to be prone to noise/interference on the video lines. For RF-based systems like the TurboGrafx-16 and PC Engine, it may be better to stick with an external option like the dbGrafx Booster for video output. If you want to use a CD add-on, you could modify the IFU/dock using one of the simpler mods since audio is already amplified. Systems that come with AV ports can use the simple mods as well and seem to exhibit less interference.
