• Bubba n Stix: in-game graphic corruption, let the demo run
  • probably VDP related, data read/writes are not accurate wrt vdp mem slots and fifo interaction
• Puggsy copy protection (SRAM check)
• Asterix and the great rescue, power of gods
  • controller doesn't work
  • add the following line to helios.properties
    helios.md.pad.asterix.hack=true

fixed as of release 22.1205

• Lemmings: in-game action bar corrupted (hint vs vint issue?)
• ISS deluxe: intro screen graphic corruption, in-game flickering
• Dashing desperadoes (Proto): in-game flickering

Hi

If can add remapping keys / buttons will be better for gameplay

Thanks

Hi,
Nice to see you're using my core for ym3438, but i wonder why did you remove original copyright from it. It is derived work from my original implementation, so it should not be removed

There's a PSG sound distortion with Mega Drive emulator (it actually sounds Sega Master System-ish), it very noticeable on player jump in Sonic games, for example. I also noticed it slightly out of sync with FM synthesizer.
I tried to port SN76489 implementation from some other emulators written in C/C++, but this gave no effect. Experiments with mixer from SoundUtil did not give result too.

sorry, my bad. studio erro

Tried a few roms. Everything so far seems pretty good. Any plans to support 32x and mega-cd?

Hello, I'm experiencing problems with hanging of the game cycle thread: the thread is paused with a regularity of a couple of seconds (CPU utilization grows on resume and becomes 0 on freeze) making emulator impossible to use.

I figured out the cause of the problem is a bottleneck in the cycle synchronization algorithm: the park method of Util class. The thread should be suspended for a 5-6 milliseconds, but it's actually led to a significant freeze and takes a half of a second at least.

I rewrote the parking algorithm and game runs smoothly without any freezes, but I have doubts about thread-safety:

public static void park(long intervalNs) {
    long resume = System.nanoTime() + intervalNs;
    while(System.nanoTime() < resume) {
    }
}

Can it fix the rendering freezes, or this problem is related to my CPU clock speed?
