TurboGrafx-16 / PC
All versions of the TG-16 / PC Engine can output RGB, some with
an adapter and others with an internal modification.
TG-16 / PC Engine External RGB Solution (no modding required)
booster: db Electronics now offers a product that attaches to the
"Turbo Booster" port in the rear of the unit, allowing for RGB output via a Genesis 2 RGB Cable (but MAKE SURE the cable includes capacitors!!!!), as well as
stereo audio, composite and S-Video. This is the solution I recommend for all TG-16 / PCE consoles that
don't use any other peripherals on the rear expansion port: http://db-electronics.ca/product/dbgrafx-booster-ttp/
Cable: There's also an eBay
seller that makes a more basic RGB solution; A standard SCART connector on one end and a connection into the
back of the TG-16 on the other. As an FYI, I've never personally tested this solution: fidde_se's RGB Cable
Duo Systems / Internal RGB
The Turbo Duo and PC Engine Duo consoles
don't have a rear expansion port, so the only way to get an RGB output is with a modification. You can do
this mod yourself, or have a modding service do it for you. Alternatively, you can buy a pre-modded Duo,
but MAKE SURE it's a reputable seller!!! I've received many emails from people who purchased
pre-modded Duo's that work poorly, or not at all!!!
Internal DIY Mods:
Here's a few options for internal RGB mods:
board This is a great TG-16 / PCE amp that sends RGBs through the
high-quality THS7374 amplifier that's had the filter turned off for the sharpest possible output.
It also has a built-in sync stripper and options for TTL and 75ohm csync.
This amp is another THS7374-based solution (filter off) that outputs a high quality image. This
board is very inexpensive and a great choice. Please note that this board doesn't route sync, so
you'll need to use composite video as sync, or build your own sync circuit. In many cases, simply
using composite video as sync works fine.
AV Driver: Tim Worthington
(creator of the NES, N64 and 2600 RGB mods) designed this amp with the PC Engine in mind. It can be
installed in any version of the console and amplifies both video and audio.
low_Budget Amp: low_budget, creator of the Super 8 is also selling an
internal RGB mod that's an easy install for the TG-16. This chip uses the THS7314 amp and while it's
still good, the THS7374 chips offer a sharper output.
GameSX Mod: http://www.gamesx.com/rgbadd/duorgb.php
places offer modding services for TG-16 / PC Engine consoles. Here's some good links:
Internal RGB mod:
Volutar / RetroFixes
Capacitor Replacement: Voultar
Region Switch: Voultar / RetroFixes
Other Fixes / Jailbars / Capacitors:
Almost all of the "Duo" consoles suffer from failing capacitors. It's strongly recommended that you
do a full cap replacement on all Duo consoles, as even if it's still working, leaking caps could be slowly
damaging your motherboard! Unless you've done something like this before, I strongly recommend having one
of the above modding services do it for you, as it's easy to damage your console. Jason from Game-Tech
has a video that shows a cool trick to make the cap replacement easier: http://youtu.be/xIIvEluVelU
Almost all TG-16 / PC Engine systems suffer from "jailbars"; Vertical lines of interference running down the
screen. After much testing, Tim Worthington found what might be the "final' solution. People are
currently testing, but it looks like this is the best solution for all models (you can ask the above modders to
try this as well): http://etim.net.au/av-driver/pcebars/
It's my opinion that if you have a TG-16 or PCE and aren't using the expansion port, just get db Electronics
solution; There's no modding involved and it's a really high quality output. If there's a chance
you'll use the expansion port, or if you have a Duo, I recommend a THS7374 board. If you decide to do any
internal mod, I strongly recommend that you do a cap replacement and jailbar fix on your console as
well, since you'll already have it open.
