DescriptionGameVersion: english,pal
SlaveVersion: 1.1 (07.12.2017)

Correct music and sound effects OR micro stuttering.
Even using this with WinUAE 4.0.0beta:
ExecutePostDisk=uae-configuration cachesize 0 immediate_blits false cpu_cycle_exact true cpu_multiplier 8
...the game will not be perfect and will show micro stuttering (start to play and move from left to right). Removing "cpu_cycle_exact true" will solve this and the game will have always smooth scrolling even with a lot of sprites on screen, but at this point music and sound will not be ok...
Is it possible to improve this slave a bit for perfect speed and music/audio routines? :)

Another thing: on WinUAE 040 requires also NOCACHE

I can't reproduce this at all and if this only happens on UAE I won't spend time looking into it.

Same for the NOCACHE thing, I've tried it on UAE with full cache emulation and it worked. What's your config?

note ~0006308

StingRay (developer)

That config has JIT enabled, cycle exact and cache emulation are disabled however so there bound to be problems! However, patch still works for me with these settings, I don't have to use NOCACHE at all.

What happens on your system, does the game crash?

No no, the "real cfg" is in the icon tooltypes changing WinUAE parameters through the C:uaeconfiguration...

The problem with this game for me is that: or music runs too fast, or there is no audio if you enable some fast emulation options. I'm talking about WinUAE in 040 or 060 mode...

Seems I've finally found good settings with no micro-stutterings using WinUAE 4.x.x:

ExecutePostDisk=uae-configuration cachesize 0 cpu_compatible true blitter_cycle_exact true cpu_throttle -900 immediate_blits true

I'm still having issues with this game timings (only) on WinUAE...
Too fast or missing music, too fast hi-score waiting in main menu, too fast mini-map view sprite walking (before you press Fire to start the game), etc.
On the other side if I degrade it too much, besides missing main menu music etc. then I see some stuttering while scrolling horizontally.
In brief, I can't find perfect settings for this game and results may change at every WinUAE release.
Looks like it uses strange cpu timings for everything this game...

Best I can do ATM with WinUAE 4.3.0 is:
ExecutePostDisk=uae-configuration cachesize 0 cpu_compatible true blitter_cycle_exact true cpu_throttle -400 immediate_blits true
but cycling through hi-score in main menu and sprite walking in the minimap are yet too fast..

challenge accepted. Game probably needs to be patched in many places to reduce speed.

note ~0009046

JOTD (developer)

fixing music timings wastes too much CPU time if we do it naively. This locks up the game because we wasted too many beam waits

music + sfx engine is too badly written. note that when game is paused music plays properly. sfx trash it.
