So far, I have bad news as I've not yet found the old jump point that I found 10 years ago. But I've taken a look at the game data itsself and modified the RF.TRE files. Yeah, sure it's no problem to get a Centurion flying 14.000 kps or faster 😁 ... but that's not the point.
So as you might know, it's possible in Righteous Fire to fly directly to Eden from the beginning of the game. Just go to Rikel and use the hidden jump point that I mentioned before. You can land on Gaea Retro base, but you can't visit the temple.
But now the interesting thing: You can use the jump point back to Valhalla. But as the jump nav point 4 is not yet visible, you don't get to the position of the jump point but to the coordinates 0,0,0 right to the center of the map. And there is no jump point, so you can't get back.
Now I've played with the sector data. Even though there are casts and sphere IDs, you can easily change a nav point target. Just use the sector number in the JUMPTYPEJUMP block and change it. The game seems to look in the target sector, if there is a jump point that leads to the sector you are coming from and puts you there. If the target sector has no connection to the sector you are coming from, then you get to coordinated 0,0,0 and no jump point is there.
That being said, I've tried out Perry Nav 1 and changed it to all 68 err.... 69 .... yes, 69 ... sectors as target. In the systems, that are connected to Perry, you get to the specified jump point. In the sectors, that are not connected you get to 0,0,0. So that means, there is no jump connection from Perry to another system. Even not to Rikel... there's just the text "JMPRIKE" ... even if you use the reserved Cast ID 4 for Rikel ... it does not work.
So for me... there is definitely no connection between Perry and Rikel. And I was quite sure that the secret jump point I've found ten years ago was not in Rikel.
However... the secret jump point could still exist and point to Perry. But in Perry, there is no jump point back. That could indeed be the case that I've experienced ten years ago. That would also explain, why I didn't wrote up the jump point position in Perry, because there was no jump point.
Anyway, I've changed Nav point 1 in perry to target system ID hex 45 (=69) ... and oops... I've reached the TestBed.
The image shows the modified GAME.GOG file opened with an hex editor. I changed "2f" to "45". The positions 24 and 1d underneath show other system target IDs. 45 = TestBed.
Please notice that the sector data exists twice in GAME.GOG file. The first occurance is from PRIV.TRE and the second from RF.TRE.
And here's how the TestBed looks like:
There're ships at every nav point of every fraction type.
Nav 1 = Merchant, Nav 2 = Confed, Nav 3 = Mercenary, ... and so on...
Here are some more screenshots:
So if you want to try it out... just use an editor and give it a go...
Anyway, if I still find the hidden jump point, I'll let you know.
