There's really no good reason to use an old beta version. I advise you to use the most recent version, which is the one I linked to in my previous comment.

As I wrote, I advise you to not use the SDL build but the native build. The SDL build is slower but has the benefit of being able to emulate an Amiga with graphics card (P96), which Deluxe Paint cannot use anyway. When using the native build, make sure to enable "amiga.use_overlay" in the config file. This way you can scale UAE using the graphics card with no additional CPU load.
