The gist of it is that Alicesoft's titles are almost all on Windows, but many of them were released on old versions of "System," the app that runs the game. Not only do old versions of System not work on 64-bit Windows, but for various reasons, we have no way of localizing them. Rance 4.1 and 4.2 are part of this set, and despite a very talented translation team that managed to solve the second problem (for those games only), they still have to be run with the help of a seperate program, which is a hassle for casual players.

Luckily, I found an open-source port of the versions of System in question, so I'm trying to upgrade it so that all those games can be localized by others in the future by others. I'm starting with Little Vampire, the simplest game, and will probably work my way up to Rance 4.1 and 4.2, the most complicated games (and will copy and paste the fan translation into my new version). It's going to be a long process but it opens the door to just short of twenty games that were basically dead to English localization, so I think it's worth the effort!

Ah, you know what, I bet you're right, this would hardly be the first time I've seen a word filter pretend to be something else, either to hide what they're doing or just out of lazy programming. I'll add that Evenicle hardcopy link for you given the trouble, thanks for point it out!
