|
| Hi, all - I was reading through the sources, and I noticed that starting with 0.2.3, there was no dsound_play. Does anybody know why the 8 kHz sound playing subsystem was taken out? That was, IMHO, a way cool feature. Was it just too buggy? Also, I (...) (23 years ago, 10-Jun-01, to lugnet.robotics.rcx.legos)
