Hi,

Okay, the beta is ready for testing. This mainly includes the sound fixes including the fixes to PSG (which is now more accurate) and cycle accurate sample support which makes sound very accurate and clean (and handles fast DAC writes efficiently Wink ). Another thing which is included is ROM/RAM switching which fixes SRAM issues in Sonic 3 and Knuckles.

Download from here. It includes all the minimal things needed to run. Changelog is in there as well.

stay safe,

Version 0.93
------------

* Implemented frequency counter overflow bug.

This finally fixes the one instrument in Ariel, Shaq-Fu, Spider-Man: The
Animated Series, Scooby-Doo Mysteries, etc. Thanks go to Nemesis.
Fixed only in SuperHQ mode.

* Added SSG-EG support to the YM2612 core.

Thanks go out to Jarek Burczynski, Tatsuyuki Satoh and Nemesis.
Surprisingly, more games use it than I thought. It is used by Alisia´s Dragon,
Asterix, GhostBusters, Buba N Stix, Top Gear 2 etc.
I am sure there many more games that are using it.

* YM2612 envelope generator now gets updated at approximately every 2.43 cycle.

* Added correct CSM mode support. Thanks to Nemesis again.

* Implmented cycle accurate sample generation.Thanks to Eke and Nemesis for help in this.
Fast DAC in some games is now fixed and all games now sound more accurate,
clean and better.

* Improved PSG noise emulation. Thanks to Maxim´s docs and HardWareMan, Eep386.
Listen to Robocop vs. Terminator, Captain Planet intro.

* Fixed Combat Cars two player mode screen.

* Optimized the YM2612 core resulting in nice speed increase.

* Optimized the VDP rendering code resulting in another good speed increase.

* Fixed sound in some Chinese games. GoodGen lists them unknown. But they look
very nice.

* Fixed Time Killers and Onslaught lock-ups.

* Improved 6-button pad support a bit. Fixes controls in Mortal Kombat.

* Fixed Menacer support. The only game that I know of which uses this is Menacer
6-in-1 and it requires the Menacer to be plugged into port two. Capture
and release the mouse with F7 (default).

* Added overclocking support (68k only). The setting is not saved. Takes
effect immediately. Will break timing sensitive games for sure.

* Fixed a small bug in VDP timing which would cause a one line glitch at
the bottom in Lotus 2, Kawasaki Challenge and some others.

* Fixed flickering in Zero the Kamikaze Squirrel.

* Implemented ROM/RAM switching support. Needed in Sonic 3 & Knuckles,
Phantasy Star 4 and Story of Thor.

* Complete rewrite of the frontend timing/synchronization code.
It has the following advantages:

- No periodic sound skips anymore.
- VSync should now work better and work on more PCs. PAL games too shouldn´t have stutters anymore.
- It is very fast.
- No emulation hiccups
- Regen is now much more responsive

* Debugger disassembly fixed.

* DAC sound in Mega Turrican and some others fixed.

* Changed VDP timings a bit. This fixes Streets of Rage intro not showing up.

* Improved region detection a bit.

* Regen is now linked with MSLU library to make it work in Win9x.
You will need unicows.dll. The startup time will be a bit slower on
WinXP and above than previously.

* Hopefully fixed the bugs with the lowpass filter.

* Regen does not use 100% CPU while paused.

* Regen is now compatible with WinXP visual styles.

* AVI recording is broken for now due to new sync code.

* New style changlog file which is more readable and pleasant to the eyes . Thanks to Adam.
