#150 x64 Cartridge Freezer/Banking Issue

[Fungus]

When using Action Replay (v5/5.1) PAL or NTSC, using the freezer while a piece of software is running (pick any game, I used Cyberdyne Warrior) using the cartridge freezer fails 90% of time, and ends up with PC = $980E (invalid return address from stack) The calling JSR is at $980C in the cartridge ROM. On a real C64 you can press freeze and continue execution nearly limitless times and very rarely will it crash like this.

It's also related to another bug when using the monitor (not in frozen mode) where the graphics displayed are just garbage from the AR rom. Scroll around in the monitor to see it, it's easily reproducible.

Vice versions tested where this occurs, all versions since 1.6 or so, including latest win32 svn build available from csdb link.

(note for groepaz, if my REAL AR exibited this behavior I would have tossed it out the window and never NTSC fixed anything.)

you didnt tell wether you have been using x64 or x64sc - i can only guess that you are talking about x64 :) i can reproduce this with x64, lots of crashing ahoi ..... however with x64sc, not a single crash when freezing/restarting a couple of dozen times (in the title screen of cyberdyne warrior). so the solution is: use x64sc :) you very much want to do this anyway, especially if you are doing ntsc fixes =P

no, this is completely unrelated - this is because vic fetches in ultimax mode are broken (and can not be fixed) in x64. it works better (although not perfect, this is work in progress) in x64sc. also its just a cosmetical issue with no impact on the emulation (other than visuals). it will get fixed 100% (in x64sc) as soon as a proper testcase arrives :)

Yes works in x64sc, thanks again.

[gpz]

lowering priority, wont fix for now, as it works in x64sc and likely might not be fixable in x64 at all

[gpz]

closing, as fixing it in x64 would probably require more than one super ugly hack. use x64sc :)

Fixed in r26311.

The problem was that the 3 cycle bank switch delay was triggered after the complete NMI handling if the interrupted opcode was only 2 cycles long. Because of this the fetched interrupt vector address was wrong.
