Archived versionsSource v4 - Timer support, complete CPU core overhaul, Dynarec actually caches compiled instruction blocks now, DSP register read/write support, plus too many minor things to note!.
Source v3 - DSP support! Timers are still busted, so songs don't play yet.
Source v2 - Added debugger and you can now single step through the CPU using the A key. Still no timer or DSP support, so it's only useful as a debugging aid.
