My friend that puts up the files is MIA the last few days. Thoul, if he doesn't turn up would you mind me emailing you the updates?
The only ones I would suggest you keep on this site are V2.3, and both V1.0 and 1.1 of the Instant Death invulnerability ones since they are such a departure from 2.3. 1.0 is much more difficult in the random encounters than 1.1. I think that would allow the player to choose from the best of the variety without overloading them with every revision I made.
Neithird, I continue to brainstorm, but I think I've pretty much done all the overhauling of PSIV that I can. I've moved my thinking to the other games in the series. I've looked at the code of PSII, but there's a lot I don't know about it. I'd love to tinker with PSI... I should go check it out!
