Dyna-Compiler (dynarec) refers to the dynamic recompiling engine. You will usually want to leave it on. If you want information on how it works you can download my doc here: http://1964emu.emulation64.com/download/1964_Recompiler.zip.
1964 1.1
In this dropdown list box there are two options available:
- Dyna-Compiler* This is a compiler engine that compiles blocks of code on-the-fly as they are encountered, thus the term "dynamic". Once a block of code has been compiled, there is no need to compile it again, unless the compiled code buffer is full. 1964 allocates a 16 MegaByte compile buffer. This is fast and is the default setting.
- Interpreter With this option, there is no compiling of code, but this is much slower than the dynarec because the interpreter must decode each instruction every time it is encountered before it can be executed.
The name "Core" is a misnomer since this only represents part of the entire core, although most of the core emulation time is spent in this area.
