Jazz Jackrabbit 2 Online

@Anubis: you can use some Latin lookalikes
Last time I tried it didn’t work well, since I couldn’t fit the text in the fields, but that was because I was trying to edit the language file directly. And I guess the program allows you to change string sizes.
Of course, this solution isn’t very good, so there are two alternatives – either to transliterate (which I’m not fond of at all) or alter the animations file to feature Cyrillic letters. If we replace some of the other, non-English, characters with Cyrillic, we’ll even be able to write in Bulgarian. By sending chat via SaLLoG (hopefully I got the capitalization all right), you can check which letter is which. However, sending those through the game’s chat would require additional tweaking.
It’s uncertain if there’s much use of any replacement though – since most servers run with Plus, large portion of the messages would remain in English, as long as you don’t translate plus.dll’s text as well and host a Bulgarian-only server.

I can see the levels look nice. And they’re quite good for a small game with a maximum of three or four players. However, when I saw them hosted on a server with about ten players in, playing there wasn’t exactly what I’d call fun. Still, it’s worth downloading the pack and giving it a try.

I can see this program being very useful. It helps coping with the chaos in your Jazz Jakrabbit 2 directory by placing all the TSF-only files in another folder. I’d have found it more convenient had it had a prompt (or maybe a command line argument) allowing you to place the files in a directory you specified yourself. This way, you could have it place the files directly into your TSF folder.
I really like the interface, with no useless information there. It just lists the files that need moving. And then they’re moved to a new location.
I’d certainly recommend downloading this for it perfectly does what it is meant for.
