I will be happy as long as it has no side effects in the netplay.
the word "desync" gives me a little fear. :eek:

Your fears aren't without warrant, that's why I don't like messing with the timing of games that have been working great for years.  But don't worry, if something goes wrong we can just change it back :)

the updated do/donpachi driver's w/2 frame reaction time have been sent to the libretro fba guy (barbudreadmon), if everything goes well they will be in the fba core in a few days.

Thanks! hope all will go well with that change.

I thought FBA was using older MAME drivers that got modified over time, guess I was wrong.  :p

And I most surely used it to play cps games back in the days reading a brief history now...

Just went through Dodonpachi in RetroArch, didn't see any issue and I used the new read ahead feature to have next frame reaction.

Great work, thank you! :)

Details explained here.


It's hit or miss with fba depending of the game, I opened an issue to discuss it here.

Well, it's working now. :)

It was missing something in the serialization part and an additional fix in retroarch run ahead code.
Now it's good if you use the 2nd instance mode, no more sound issues, I just finished Batrider with 4 frames of lag removed.
That's pretty neat!
