So what is the plan if this gets enough interest from potential voice actors, and assuming you get access to the script?
I'm confident we can get access to the script, once Beacause R02 is released, though due to the nature of Beacause, some decisions will need made (canon names vs. accurate translated names, spells, etc). This won't affect nameable party members, obviously, but for characters like Reno (correct translation Leno), this could make a big difference.
I'm not entirely sure what the work structure on this project is going to be outside the voice acting itself. I intend to do the boring stuff, checking filenames, etc., and am up for any audio editing that needs done, such as correcting levels, EQ, etc., depending on how much free time Shard and Aussieroth have (I'm confident they both have the needed technical ability here). Ficedula has volunteered for any programming work needed (thank goodness), though hopefully that won't be too much beyond what he's already released; we'll have to deal with any issues as they come up, as it's too early to tell what we might run into.
In terms of immediately after script is available, as far as I get the distinct impression Aussieroth is going to handle casting. The specifics would be up to him, but I'd imagine it works out similar to how Shard's FF8 casting did, with casting calls being posted on a few VA sites, as well as notifications sent to people who have done FF7 voice related projects in the past and might be interested about said casting calls.
Once auditions are finished, Aussieroth will handle management, scheduling, etc., and (I think?) Shard will be doing actual voice direction? I'm not entirely sure on the specifics here, but one way or another it'll get worked out.
At this point, the big issue is just that it's impossible to work out a timeframe until Reunion R02 is released. While he waits for a touphScript update he's doing another runthrough for a chance to polish it just a little more. Once that's done, if touphScript's new version still isn't ready, I'll ask him about letting us use his raw text files as a stopgap to work from until it's actually released.
