Here are a couple of reasons, from four pages ago...

But the primary reason is: the coder doesn't want to release a public beta yet.

Which I simultaneously realized is probably the reason why I have never been able to start writing one, as by the basic concept, I didn't see the difference between it and an interpreter written in assembly, and now I realize there is no big difference, it is simply an expanded version that better takes advantage of the features of the host processor. Oh, so yea, in order to find out I carefully reread a few websites that I had been to before, and really take it in.

You're missing a crucial point--the translation cache.

Each block of code that's translated to native code is stored in a cache--that way when the emulated CPU wants to run it gain, it's already translated and just waiting to be executed

Could you dip into the private coder forum for a bit?

Does anybody have an idea, on how long it will probably take though to implement a dyranec engine for the PS1 if its being coded completely from scratch.

**Tinnus** · October 4th, 2006, 23:58

It's hard to tell. Depends a lot on luck, the coder's skills, and debugging capabilities.

The problem to debug a dynarec, though, is that you generate code at run-time, and dynamically-generated code cannot be hooked up to a debugger to, say, do breakpoints, step through code or anything like that.

Hi guys, I'm new here to the forums, and I wanted to ask a question. How is the anonymous coder making the PS1P faster without a dynarec engine? I'm not a coder, but I wanted to know.
