Ech. Well, if you're gonna go SVBS, you may as well go Tankentai. It's complex and messy, but it does the job better than any other scripts, IMO.
THe current version, 3.4, is easily found on other sites; its translator lives on another forum, but a quick Bing search and you're there. Installation is simple, you just DL the demo and then copy the code in the demo to your scriptbox. Easy.
The hard part is configuration. There's a whole bunch of options in the script which you HAVE to configure- these scripts are NOT plug and play- and that's where my advice has to stop. How it's configured largely depends on your needs. You'll also need to have certain graphics from the demo copied into your resource DB as well; those are dependant on whether or not you're using the ATB plug-in or not. DO NOT forget to follow ALL the instructions in the read me file that comes with the demo.
If you do use the Tankentai script and are having trouble, I can try to help you out more. Just post a specific question and I promise I'll do my best.
