PC Speaker emulation is much faster than the Sound Blaster 16 bit emu.
I would stick with PC Spreaker emu until I could tweak the performance of the other emualtion.
Also looking at the DosBox code, the Sound Blaster emu isn't fully working so it's proberly causing all our slowdowns already, as if my Athlon X64 CPU can't take it the gp2x can't as well...
I'm sure PC Speaker emu is best for us at the moment though until the DosBox team work out all the bugs and slowdowns in the SB16 code.
I'm hoping to have a release soon people, I'm sorry if I'm keeping anyone on the edge of there seats lol
You where lucky for me to port the first one, I'm glad I did and I hope my second release hits the same people and works better than the last.
All the best.
