I've been doing some research on the subject for myself. There's probably nothing new to you, but I found this article very informative:

This whole rewrite-zx-project is taking a lot longer than I expected.  I learned a lot of things, though.  Notably: the ZX Spectrum isn't the simple machine I thought it was, and some of the games are really fun and creative - though, one has to plow through a lot of crap to find them.


right, once you dive into the timings (to get it 100% perfect you need fully stallable mid-instriction interruptable z80 core) it becomes very complex.

and yes, the 8-bits had some amazing games back then, and today.  If you've not checked out the recent Amstrad CPC port of Pinball Dreams I highly suggest you do (MAME isn't good enough to run it) you could easily forget that's on an 8-bit, it plays just as well as the Amiga original.

If you are looking for a good CPC emulator I can't recomend CPCEC enough. It emulates the entire range (many other emus still struggle with the CPC+ carts) and can auto-start games.

The author cngsoft is well known in the Spanish CPC scene, he even programmed a pretty cool remake of "Bubble Bobble".

charles32k, the real problem: it had BurnDriverD, notice the D at the end ?  this means it only shows up in debug build.
I remove just the D, it's OK now.

Hi,
Added a little stereo-izer effect to the NES emulation in FBNeo - it's accessible via the DIPs.
Code is on github, if you'd like to try it :)

Here's a video demonstration
https://www.youtube.com/watch?v=miptXdz09p0
0-23 seconds: normal recording with effect off
25-end: recording with stereoized effect ON

best regards,
- dink
