A bugfix & update for BlueMSX fans :)
Don't let the term "betatest" keep you from trying this new version, a lot of care has been added (over the past 5 years or so) to make things right
Thanks, dink, for your contributions, especially the save state bugfix (joystick was stuck with some games when loading a save state)
Indeed, the list of changes is very long. This beta comes without any installer. If you get a Windows message when starting blueMSX.exe, you need to install the DirectX End-User Runtime :

Be patient with this installation and wait for the end of the installation of a long serie of .dll files !
Metalion, the Save Stage bug was first reported 6 years ago, and was only fixed last weekend. So please patiently wait another 5-6 years for the new fix. 
Ok, so I'm joking Maybe we can figure it out quicker this time.
mars2000you, its the least I can do, no thanks is necessary I have one small favor to ask, could you zip up all your cheat files (blueMSX\Tools\Cheats\*)and link them somewhere? I don't have the patience to create the new files from the posts on the other forum, and I'm sure others would appreciate this as well.
best regards and happy retro gaming,

BS warning. I reported the R#13 bug already 23.10.2008
About same time I also told that blinking is affecting wrong video frame in text mode and that ie. VDP(24)=4 does not work correctly on SCREEN 0
mars2000you - excellent, thanks for the heads-up
