Help test x64sc, the next generation x64.
We've spent a month and a half rewriting x64 into x64sc and would like to have some feedback.
Please test this with as many things as you can and report any emulation bugs you find in here or alternatively on #vice-dev @ freenode.net.
Let's bring VICE from the 90's into the modern age!
Good:
- emulator rewritten, more accurate
- models:
Breadbox (default) x64sc -VICIImodel 0 -ciamodel 0 -gluelogictype 0
C64C x64sc -VICIImodel 1 -ciamodel 1 -gluelogictype 1
C128-ish x64sc -VICIImodel 1 -ciamodel 1 -gluelogictype 0 Bad:
- slow (will be faster)
- possible regressions, please test
- no NTSC (yet)
- no REU (yet)
- no snapshots (yet)
- mystery drive bug (disable virtual device traps)
- GUI not yet updated
Win32 binary: x64sc-r22294-win32.zip
Source code (subversion repository):
svn co https://vice-emu.svn.sourceforge.net/svnroot/vice-emu/branches/..

Quote:great! Already tested Pain/Agony hidden part and works only in x64sc+AR4.2. Isn't really possible to fix it for x64 too?
it is fixed in x64 too (cart system really behaves exactly the same in x64 and x64sc) - thing is that the whole code is very unstable, and starting the hidden part often doesnt work (just try a few times).
the AR this is supposed to work with is the 7.3 "atrax" hack btw :) |

I can run tests on my Drean C64C, silver badge c64, C64G and my SX-64 if that helps anyone. |

I may very well have been dreaming but I *think* Goto80 mumbled something about recently getting a Drean 64.. |

Will it have the ability to remember that I want true drive emulation every time I open a D64? |

Is 1571 emulation broken in this? When I try to attach a d71 file in both .exes I get an error box that says "Recieved signal 11 ()".

I took a look at the current X64 sources and noticed that the Drean clock parameters are based on the patch I submited to VICE Team back in 2006, but I had made a mistake and the clock value was wrongly stated as 1.014 MHz.
2 years later, in 2008 I noticed the error and, with better data, found the correct clock frequency to be 1.02344MHz
Thus, c64.h must have
#define C64_PALN_CYCLES_PER_SEC 1014000
modified to:
#define C64_PALN_CYCLES_PER_SEC 1023440
See here:
http://www.solid-state.com.ar/index.php?entryid=11
and here:
http://www.solid-state.com.ar/index.php?entryid=86
for the data backing up this clock value. |

If I attach a d71 with 1541 selected all I got is a drive error while trying to load the dir. Selecting 1571 and attaching d71 works here. |

New version: x64sc-r23120-win32.zip (x64sc & x64)
- distribute restore key presses randomly across a frame
- Normal/Full/Debug borders switchable on the fly (only x64sc)
- Improved accuracy of NTSC emulation (sprite/light pen coordinates)
- Improved accuracy of PAL-N emulation (sprite/light pen coordinates, clock frequency)
- as usual, too many cart fixes to mention
Special thanks to the people who volunteered to run test programs that provided crucial information:
- hedning, The_Woz and Thierry for Drean (PAL-N) testing.
- Jason Compton for testing a great many NTSC machine configurations.
All test programs (PAL/NTSC/NTSCOLD/PAL-N) are available in our subversion repository for other emulator writers to use:
http://vice-emu.svn.sourceforge.net/viewvc/vice-emu/testprogs/
Please consider contributing your findings. |

@tlr: Are there any particular test programs that would be helpful for you if people tried out?
