[PocketGo2 v2 / PicoDrive 1.96] Freezes in 32X games. #5

Closed DrUm78 closed 4 years ago

DrUm78 commented 4 years ago

Hardware: PocketGo2 v2 O/S: Rogue FW 1.0.9 for PocketGo2 v2 Software: PicoDrive 1.96 ROM: Virtua Racing Deluxe (JAP) 32X version ROM MD5: 08cae0a96d9ee07001c6e1c247d407c6

At any moment (during a race or in menu) the game may freeze. The emulator keeps working though. Sometimes you can get a freeze every 10 minutes, sometimes not during 1 hour. Really random. Sometimes the emulator crashes too but that's very rare. All the OPKs I tested have this issue. I did not get freezes on other 32X games but I play much more to this game than others.

See the attachment (savestates during the freeze): virtua_racing_32x_freezes_savestates.zip

This happens in Virtua Fighter 32X as well so most likely on every 32X games. Title edited.

Most probably a cpu synchronisation problem, since the emulator doesn't seem to freeze as a whole. I don't think it happens in every game. I'll have a look in the save games to verify this.

Do you know if this is happening in the intro as well? That would make it easier for me to reproduce since I wouldn't have to play for an undetermined time. I would also like to ask how often this is happening to you. Have played the first levels several times, but didn't occur.

Yes that happens as well in the intro. Just let it run and you should get it (sometimes after 10 minutes, sometimes after 30 minute to 1 hour). One or two of my saves are from the intro I believe.

Here is my config file (from 1.95 version). Better you have it as sometimes we can reproduce an issue only with some specific settings (was the case a few days ago on FBA SDL with goldmojo, the culprit was the vsync mode). config2.zip
