currently i am playing version 0.50b
0.50b? The official Vx Ace 0.50b?
One version of the game to rule them all, One version of the game to find them, One version of the game to bring them all, and in the darkness bind them; in the forum thread where the pirates lie.
i can't advance in the relationship events because it is grayed out and it doesn't tell me the points i need to advance
I need more details. What is your current relationship level with PM? Did you complete every relationship event available? Did you visit the beach? Did you visit the Titan Step city?
Besides, I'd love to put my hands on this precious version of the game too...
For verification purposes only, of course...
in which version can i unlock PM as a partner?
It should be possible to achieve in every available version here; from the Vx Ace 0.50a to the latest MV release. Your version included, assuming that the 0.50b is what I think it is; the last Vx Ace game version released before the engine switch, about which I only read rumors.
If I remember correctly, your relationship with PM needs to hit level 4. There will be "An Alchemist" relationship event available you need to trigger. Only after that, the game allows you to choose PM as a follower whenever you exit the capital city.
