[RetroArch] Picodrive Netplay Desync Issue

[Chaos81]

I am running RetroArch 1.7.3 on both a Win 7 64-bit and a Mac running OS 10.11.6.
The Picodrive version I am using is the newest build (1.92 1a49e06) on both systems (as of 6/28/18).

I noticed an issue playing NHL '94 for Genesis. When playing 2 player via Netplay, a minute or so into gameplay, the game will desync. There is no "netplay disconnected" message seen, what occurs is some strange play behavior by the opposite team, and when asking the other player, we find that our game clocks are not in sync. I tested against 2 different people, one running Windows 10 64-bit, the other Windows 7 64-bit. I have tested against both people with me running Win 7 and Mac OS. The verbose log for RetroArch does not show any netplay errors.

After bringing it up in the RetroArch Discord, it was suggested to test locally, running 2 instances of RetroArch. When doing this, I saw the same issue. I checked my Netplay settings, and they are all defaults.

I then tried Streets of Rage 2 (USA) locally running 2 instances, and this ran OK. I tested for about 5 minutes with no apparent desync.

I have played numerous games via Netplay with Genesis Plus GX with no issue, but would like to use Picodrive because of the cross-platform compatibility.

I attached a screenshot of the NHL '94 desync and the retroarch log files from both instances. It was taken about 1 min of game clock into the game (approx 40 sec or so). Desync seemed to occur right around this time.

Please let me know if there's anything else I should check.
