first of all i'm sorry but the device took way longer than expected to arrive.
I just got it today and i have issued a bunch of fixes.
SMS Plus GX doesn't use the IPU right now (seems that the IPU is being ignored, despite it working in PCSX4ALL as intended) but it works ok for now.
I'm not very happy with it but at least it runs smoothly and better than the older version of it.
Handy is also now working properly but it seems that the left stick is maybe a bit too sensitive ? Let me know guys if that's the case.
I'll work next on porting NGPCEMU and adding Dual analog stick support to the Wonderswan emulator.
EDIT: Made a quick port of Picodrive with the better 32X MIPS JIT. The new JIT for 32X works somewhat smoothly, 40~45 FPS for Virtua Racing.
EDIT2: Re-applied the triple buffering patches. Redownload the OPK if you downloaded it earlier. I'm now hitting 60 FPS for Virtua Racing.
Downloaded the latest of your PCSX4ALL compiles and half the games the buttons don't work.
Air Combat - no buttons work
Ace Combat 2 - buttons work
Ace Combat 3 - no buttons work
Also, it's not running as smooth as the older versions were. Lots of stuttering.
Handy also seem to require a double-press of the buttons to get them to work.
SMS Plus seems to be working OK.
