*Some modern HDTVs aren’t able to display 240p signal, the native video resolution of the Atari Jaguar. It is not a limitation of the JAG2GEN but rather your TV. To support your Atari Jaguar on a TV that does not support 240p signal, you should consider buying a scan converter of some kind.
**SCART cable components vary. Some use CSYNC other use Composite on SYNC and most filter the RGB signals. If you plan to use a SCART cable with the JAG2GEN, you may need to modify the cable to work properly with the Atari Jaguar as they were intended to be used with the Sega Genesis. This isn’t a limitation of the JAG2GEN but rather an expectation of SCART and the Jaguar’s RGB and Sync lines.
What is the JAG2GEN?
The JAG2GEN is an adapter that simply converts your Jaguar’s AV signal to that of a Genesis (model 2 or 3*) AV cable.
Will it make the Atari Jaguar’s picture quality look better
The JAG2GEN does not upscale the native 240p signal from the Atari Jaguar. It does however provides the best analog output (RGB) from the console. The Atari Jaguar already provides the proper 75ohm RGB out and the JAG2GEN outputs those same signals directly through a more common 9-pin mini din (Genesis 2) socket. For razer sharp pixels, we highly recommend using the JAG2GEN with a modern scaler like the OSSC or RetroTINK 5x to get the best picture quality.
What type of Sync is used in the JAG2GEN?
The Atari Jaguar outputs TTL level CSYNC natively. The JAG2GEN attenuates the native Atari Jaguar CSYNC voltage difference to equal the expected 75ohm output. Because the JAG2GEN is intended to be used with Sega Genesis 2 cables, there should be a 470ohm resistor and 220uf capacitor inline on the SCART cable you’re using.
What are OSSC optimal timings for the Atari Jaguar?
OSSC Profiles will need some tweaking to fit your TV and Cable needs. Here is a good starting point:
Video in proc
Video LPF = 35MHz
Sync opt.
Analog sync LPF = 10MHz (med)
Analog Sync Vth = 180 mV (Only for SCART with CSYNC)
Output opt.
240p/288p proc = Whatever lineX mode you prefer.
LineXx mode = 320×240 optimal
Sampling opt.
Adv. timing > 320×240:
H. samplerate = 422
H. synclen = 31
H. backporch = 23
H. active = 360
V. synclen = 3
V. backporch = 11
V. active = 240
Sampling phase = 303 (this can vary)
