<blockquote>Ok, brief update time! I've been working on rewriting the dynamic recompiler from scratch for the PSP. A few months ago I started writing a PSP port of the original dynarec, but I quickly realised that I'd need to take a whole new approach if I wanted it to fit in memory on the PSP. If you've not heard of dynarec before it's basically a way of speeding up the emulator by recompiling the rom's code for the target platform (i.e. the PSP) rather than interpreting instructions one by one.

I'm basically using the same approach that HP used on their Dynamo dynamic optimiser (I talk about it a bit more here: http://strmnnrmn.blogspot.com/). The cool thing about this approach compared to my original attempt is that it uses far less memory - I think I will be able to get it running in less than 1MB ram, compared to around 10MB that the PC version used.

I've still got a lot of work to do before the dynarec is actually usable, but I'm hoping to release another build sometime over the weekend with a bunch of additional graphics fixes. In the mean time I'll try to post a few more progress updates on the site above.</blockquote>
