Here's another version of this ZX Spectrum emulator:
What's new:
- Fixed some instruction timings
- Added bus contention for IN and OUT
- Replaced the memory contention emulation using a more precise model
With all of this timing has improved a lot (Aquaplane's border change is now where it should be), but it's still not perfect (demo effects in Overscan or Shock Megademo show some small glitches). I've also set the CPU speed a bit higher (170/125), but I must make some tests to check if it's necessary or not.
