Well, weirdly a lot of people are having trouble finding the full game to translate as most have found only less than 65 mb files as I've been reading the older comments. However, can't someone just buy the original over 400 mb files from the DLsite and figure out how to translate from that or does it not work like that?
H-Sharing has the 1.10 version (e.g. the latest version) for download. Yes, it's not 400 megs, but I doubt that's an issue.
It most likely means the original dlsite package contained some irrelevant stuff along side the Windows version.
I've found that sometimes you get a package containing the game multiple times (incl. a Mac version for instance).
Also, I wouldn't be surprised if the 'pirated' version just doesn't contain the RPGM RTP. Which might've also been included in that 400+ MB package.
I'm pretty confident that H-Sharing's not putting up a demo there. Also, the demo is only 34MB, not 66.
Anyway ... just MTool it if you really do want to play it.
