Alpha sprites are one of Select's really nice features. Sadly, I would imagine that we are unlikely to see the same technology on RO5/ROOL, unless cooperation between the two companies really takes off. It's a bit frustrating - if Alpha blended sprites were available on all systems, then more programmers would use them. I would certainly revise my themes with Alpha variants, and I believe Richard Hallas has said he would do too. But I'm not going to all that bother if the results can only be used on Select machines.
