Okay, I don't have a ton of time but I just found a way to play games such as JSRF, Fable, and the others on a 1.6 console without disc swapping, requiring the original dash, anything.
This, however requires a softmodded console with UnleashX (May work on other dashboards, I have not tested)
The steps are as follows:
Turn on your console and allow it to get to the dashboard.
Select system, then settings.
Go all the way to the bottom where Video Display is and select it.
Turn off 480p and if not turned on, turn on 720p, and 1080i.
Then, have fun and launch your game, I believe this actually forces it into 480i which is not accessible from unleashx.
I found this out by playing with the settings, you sadly can't play in 480p, but hey, that's the price to pay, I'm just trying to give an option to you folks with UnleashX.
I have two consoles 1.0 and 1.4 witch tsop. The same bios and systems, the disks are also the same. On the console 1.0 pal games dark screen and then the dashboard returns. Ntsc ok.
