Question 1

Does this not support progressive scan?  None of my games are detecting it.

Accepted Answer

It does. Be sure to press and hold b on boot

Question 2

Will this work with the Panasonic Q?

Accepted Answer

Apparently yes! Provided the model of the Q you have has a Digital AV out port, it should be compatible.

Question 3

The prism switches resolution between gameplay and cutscenes, when this happens the screen turns blank for a few sec making most games unplayable?

Accepted Answer

This is a problem with the underlying software that Gamecube HDMI adapters use which is called GCVideo. It is software that is not developed by the manufacturer of devices like the Prism.

There are two ways to fix this. If you have a modded Gamecube and are running Swiss, you need to enable an advanced option named Force Video Active. This isn't entirely desirable because you still get one screen blank for about a second at the start of each cutscene, but it's much better than the 3 seconds before and after every cutscene.

Option 2 is downgrading the firmware of the Prism back to a 2018 version, 2.4c, which was the last version this issue did not occur. You can find links on the GCVideo github page or in the CamecubeHacks subreddit.

Question 4

My gamecube model is D0L 101, will this work?

Accepted Answer

No. It’s possible but not usually cost effective to modify a USA DOL-101 Gamecube to add a Digital AV port, buying a USA DOL-001 is usually a better choice, Regions other than the USA and Japan never had a Gamecube with a Digital AV port so retrofitting a digital AV port is the only way for a console for those regions to have one. The DOL-101 reduced production costs as much as possible by deleting both the Digutal AV connector, and some of the connectors underneath the Gamecube used by modules like the Ethernet adapter that like Digital TV  were ahead of their time and  games that used them didn’t appear until the Wii generation of consoles.. Deleting the Digital AV connector wasn’t a forward looking move and it saved, less than $1. The only less savvy choice was molding the lid plastics to prevent the Gamecube from using a full size DVD in its  otherwise standard DVD drive.
