This page documents various emulator core candidates and specific user requests for systems
### DosBox
* https://github.com/schellingb/dosbox-pure
* Original Request: https://github.com/TASVideos/BizHawk/issues/2547
* Core Analysis
* Early attempts (2010 or so) to add rerecording suggesting it is highly sync unstable. Situation may have changed since then. Waterbox highly recommended.
* In particular, according to Ilari it had a lot of reentrancy with HLE operations, so you could get to a "frame end" while servicing an x86 BIOS call in HLE code, requiring the ability to save and load with different call sequences on the stack.
