I create markers in N64 movies, when I go too a previous marker, instead of rewinding to the marker, it rewinds to the beginning. I'm not sure if it's fixed in 2.3.1, it's still an issue in 1.13.2 and we'll have to deal with it. DynaRec is not in 2.3.1 which means it crashes Pokemon Stadium and turn off voices in 007 The World Is Not Enough.
--- GLITCH DETECTED ---
My computer is a high-end PC with an Intel Core i7 at 3.7 GHz, 2 TB HDD, 16 GB RAM, NVIDIA GTX 1060, running 64-bit Windows 10.
In the emulator, under the Advanced tab in Customize, I checked both Store movie working data on disk instead of RAM and Store movie working data in extended > 1 GB RAM, I have AutoSaveRAM turned on so the game will be saved on a .AutoSaveRAM.SaveRAM every 5 minutes. Backup .SaveRAM to .SaveRAM.bak is left on by default.
In TAStudio, For Default Savestate History settings, I set the Capacity to 8192 MB (which is about half my computer's RAM), Disk Capacity and Save Capacity to 65536 MB (or 64 GB), Divider for memory state interval to 64 (State Gap Divider is 1042 KB, State every 16 frames), State interval for .tasproj to 8 (State every 256 frames). For Savestate History Settings, All capacities are automatically set to 8192 MB if the Default Savestate History settings exceed that amount.
Autosave Interval is set to 300 seconds. Autosave as BK2 and Autosave as backup are on, as well as Backup Per File Save.
BizHawk is resource heavy when it comes to SNES, N64, PSX, and Saturn, requiring 4 GB RAM just to run the emulator, and 12 GB RAM and a 1 TB HDD to record movies using TAStudio on the maximum state capacity/divider settings.
Now for the glitch, if the emulator crashes in middle of saving (e.g. an exception or a blue screen of death) it gets corrupted and progress may be lost and it can't be recovered as far as my knowledge. It's always safe to make backups. Like I said, BizHawk is resource heavy and recommends 16 GB RAM or higher and a 2+ TB HDD and a reliable SSD. If you close TAStudio after saving a huge file, it doesn't just free up your RAM, your HDMI monitor loses its signal and the HDMI cable needs unplugged and plugged back in.
