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/..

Any chance for snapshot functionality?

New version: x64sc-r22983-win32.zip (x64sc & x64)

- don't access charROM on Ultimax mode VIC-II fetches (fixes hidden part in Pain)
- remote monitor line ending fixes (should work better on win32/OSX now)
- various fsdevice & cart fixes
- on-the-fly ddraw/DX9 switching
- autostart mode Inject-to-RAM does what it says
- IDE64 4.1 support
- true aspect ratio for win32
- x64sc snapshot support (please test!)
- CIA timer B bug disabled by default (use -ciamodel 2 to get the classic behaviour)

Note 1: snapshot format has changed, and may change until the release.

Note 2: x64 previously used to emulate the 6526 CIA with timer B bug.
We tested various machines but didn't find one with the timer B bug yet.
These tests can be used to find out: cia-int-r04.zip

If you have a combination of CIA1 | CIA2 | CPU different from...
MOS/6526/3884       | MOS/6526 R4/3283    | MOS/6510 CBM/3184
MOS/6526/4682       | MOS/6526R-4/2484    | MOS/6510  CBM/2484
MOS/6526/1685       | MOS/6526/1685       | MOS/6510/1385
CSG/6526A/3590 216A | CSG/6526A/3590 216A | CSG/8500/3390 24
...then please run the tests and report back!
I'm especially interested in the 8521R0.

great! Already tested Pain/Agony hidden part and works only in x64sc+AR4.2. Isn't really possible to fix it for x64 too?
Freeze also works but not saving the attached cart, you have to attach AR4.2 before loading a freeze from that hidden part, oh well =)


In x64, trying to attach the AR4.2 I got a signal 11 a couple of times but I can't reproduce it systematically :( Seems to occour if I start x64 and I attach it while the screen is black, but not always. I hate random bugs =)

Good to finally see Drean emulation on X64! :)

You can count on me if there's any test that needs to be done on a real Drean machine.

My Drean machine (CIA1|CIA2|SID|VIC|CPU):

MOS/6526/4485 | MOS/6526/4485 | MOS/6581 R3/0886 | MOS/6572R0 | MOS/8500 R3/5185

Anyone in NTSC land that would care to run a few test programs?
Please PM me.

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..
