34.1 is the version I have installed. -_-
A save that old wouldn't even be compatible with the new releases.
The indivigames Discord has an archive of game versions, so you could download progressively more recent versions just to run them once, load the save file, save the game, and quit. Gradually updating the save to a modern file structure.
Alternatively you could copy the files "p-zbrow1.png" and "p-zbrow1.rpgmvp" from your r34.1 into the folders of the recent version to make the save file load. However it would then be very glitchy, and you'd need to do a new game+ to fix it, losing all story progress but keeping stats and items.
