The mini-game is really the single thing that distinguishes BB from the other frontends.
Well attract mode also has a mini game built int (Acctrac-Man) lol It looks a little too hyperspinny to me, but I guess i can give it a whirl.
Nah, not hyperspinny at all.
The default theme is really just the front end showing off.
I can run most of the themes on a crappy socket 478 p4 and a geforce mx4000.
I've even had it running on a P3 with 256mb ram on linux with a dedicated video card using one of the plain-jane themes.
Except the ones with CRT shaders.
those needed a newer card from the parts bin or a faster processor.
i'm working on a classic vertical theme right now and it's basically creating a background and mapping out the spots you want lists & different artwork in the theme to show up.
It was overwhelming to me coming from front ends with theme editers like mala & wahcade but i think i'll have something cool eventually.
