| == Buglist ==
| |
| | |
| PLEASE NOTE: THIS IS '''NOT''' THE OFFICIAL BUGLIST. PLEASE USE THE BUGTRACKER. THIS LIST IS ONLY FOR MYSELF - AND MOST THINGS IN THIS LIST ARE SUBJECT TO BE MOVED INTO THE BUGTRACKER AS WELL SOONER OR LATER.
| |
| | |
| <pre>
| |
| | |
| this is work in progress, if you want to help with this document send mail to
| |
| <groepaz@gmx.net>
| |
| | |
| things that are needed:
| |
| | |
| - more examples of programs that do not work correctly
| |
| - small testcase programs that show a certain bug
| |
| - small testcase routines that exploit a certain bug to detect an emulator
| |
| - confirmation whether programs listed here work (or not) on the real c-64, or
| |
| another emulator, or even a specific version of some emulator
| |
| | |
| if you report a certain problem, please include the following info to make
| |
| maintaining this list easier:
| |
| - what program are we talking about? provide a web link to the program, if
| |
| possible use csdb as a resource
| |
| - what emulators misbehave, which don't
| |
| - does it work on the real thing? if reporting whether it works on the real
| |
| thing (or not), also report what kind of c64 was used (model, kernal version
| |
| etc) - sometimes very old programs rely on old buggy kernal for example.
| |
| - if you are describing a generic problem, try to be as detailed as possible
| |
| to make it easier to find out what's the cause.
| |
| | |
| please notice that list is NOT meant to only focus on vice. its just that:
| |
| | |
| a) my main desktop is a linux box, so i am using vice most of the time
| |
| b) vice seems to have the most bugs :) many of the problematic programs in
| |
| the list work fine in ccs, and even more in hoxs.
| |
| | |
| so yes, ANY emulator bugs/problems are subject to be described in this list
| |
| (that is, stick to CCS, VICE and HOXS ... i don't think any other emus can
| |
| compete yet)
| |
| | |
| thanks for contributions must go to:
| |
| | |
| Fungus (some drive stuff)
| |
| assiduous (testing lots of stuff on the real thing, list of emu checks)
| |
| iAN CooG (some more problematic programs, more testing)
| |
| GRG (confirming NTSC bugs)
| |
| Mason (more problematic programs)
| |
| Andreas Matthies (confirmed some vice bugs)
| |
| | |
| and last not least: various ppl at csdb for their comments on specific
| |
| programs.

| ==============================================================================
| |
| RULES OF THUMB
| |
| ==============================================================================
| |
| | |
| - always use d64, plain prg and t64 seem to be problematic
| |
| - always use true drive emulation
| |
| - switch virtual device traps off
| |
| - do not use more than one drive on the virtual drive chain
| |
| - set memory reset pattern to "normal". some (buggy) programs will not work if
| |
| eg the memory is cleared with all zeros
| |
| - use exact pal emulation (some color-mixing tricks will not work without)
| |
| - when using VICE, select resid-fp (some things do not work without)
| |
| - when using VICE, also try with x64sc (it is more accurate)
| |
| - first and foremost, always use the latest version of the emulator
| |
| - test without a cartridge
| |
| | |
| and the most important one: DO ALWAYS TEST ON THE REAL THING!
| |
| | |
| if testing on the real thing and reporting results, it would be great if you
| |
| could also the results of the <Box Check "Type"> program mentioned below
| |
| run on your reference C64.

| "The demo was coded on Vice 1.7 and made heavy use of its bugs. Hence it
| |
| crashes on a real C64 and bugs/flickers heavily on CCS64 and all versions of
| |
| VICE after 1.7... - LOL!!! Get the old VICE 1.7 on funet, if you want to see
| |

| |

| |
| | |
| Rubi: Needs special RAM init pattern. Choose "First byte: 255" to make it work
| |
| in VICE. This "cartridge check" will also fail on real C64 with the memory init
| |
| pattern that VICE uses by default. CPU reading from disconnected memory at
| |
| $DF00 will get the values from the VIC-II reading on Phi1. This is graphic data
| |
| for most the time (depending on the cycle) and can be the same value for 16
| |
| times or more so this "cartridge check" is crap.

| "Is it fair to use the 1541 as EMU faxxor? It's very simple to set up some
| |
| drive code that would rely on the analogue properties of the serial cable,
| |
| which would be tricky to emulate. It's all a very simple test which I
| |
| implemented some years ago. Simply generate a square waveform from the drive
| |
| to the C64 in f.e. 1KHz. Sample this waveform on the C64 in a much higher
| |
| frequency. In a pure digital world (Emulator) you would count equally many
| |
| zeros as ones but in the real world this number will differ greatly due to the
| |
| CMOS logic levels and charge times."

| "A bug I discovered in VICE when I coded on The Wild Bunch was that the timing
| |
| when an NMI interrupts an IRQ setup was incorrect. IIRC it was 4 cycles too
| |
| much in comparison to the real thing. All I remember was that I had to take
| |
| special precautions to old CIA, new CIA and VICE CIA. I'll try setup a test

| hundreds of times, I've only tested on real 1541s a dozen or so times. However,

| *** [vice] problem with keyboard emulation
| |
| | |
| - [vice 2.2] AB/Zap http://noname.c64.org/csdb/release/?id=17634
| |
| | |
| A: works with VICE v2.2.x(SVN) (r22447)
| |
| | |
| "In part 2 (the one with Drago's Porsche picture) the space detection works
| |
| badly (not at all in VICE). Simply pop into the monitor and continue from
| |
| $139c to go on."
| |
| | |
| "abo: There is a single raster interrupt from line 0 to line 305 each frame.
| |
| Within the remaining lines space is checked by the main loop. The problem is
| |
| that the irq terminates by calling $ea31. This routine consumes much more time
| |
| if some key is pressed, so the irq extends to line 15 - just to be re-entered.
| |
| So effectively main loop is not executed if any key is pressed.
| |
| | |
| This means one has to press space exactly in the moment main loop is executed
| |
| in the last 8 lines of a frame. No wonder space detection works badly.
| |
| | |
| It does not work in VICE because keystrokes are only distributed randomly up to
| |
| 16383 cycles starting from line 0. I will raise this limit to 312*63-1=19655
| |
| cycles in post 1.22 releases, so this demo will "work" like on the real thing
| |
| then.
| |
| | |
| The proper fix for the demo is to jump to $ea81 instead of $ea31 to exit
| |
| interrupt as the main loop directly checks $dc01 and thus does not need any
| |
| lengthy keyboard scan."

| frequent and perfectly predictable. They occur 3 times per tune duration - at

| the melody sees a rapid change. In VICE, the flickers are very frequent and

| they cause the tune to restart at times."

| |
|
| |
| "Audio buffering is a requirement for any software based audio playback. The
| |
| option is there to set the buffer to a lower value for those with fast
| |
| machines, which makes the problem less apparent. Impossible to work around."
| |
| | |
| "still there is no option to set it below 100msec. And that's still quite a
| |
| lot! why not allow 50msec? or 20msec (== 1 frame). My pc wouldn't be bothered
| |
| by it."
| |
| | |
| "For windows there are ASIO or WDM drivers for many soundcards that will allow
| |
| near realtime audio (a couple of milliseconds or less in latency).
| |
| A selectable buffered video to match the lag of the audio could be useful for
| |
| watching timed demos."
| |
| | |
| "Simply delay the video update to be in sync with the audio..."

| | |
| A: this has drastically improved in 2.2, much smaller buffers (and thus less

| *** [vice,ccs] palette has "wrong colors"
| |
| | |
| this is often complained about, but it is _not_ a bug. read peptos research
| |
| page to understand how vic colour generation works
| |
| (http://www.pepto.de/projects/colorvic/)
| |
| | |
| the essence is, that there are infinite "correct" palettes. whether the palette
| |
| matches what you know from your c64 depends on many factors, like your c64,
| |
| your monitor, the operating system you use on your pc, and your pc monitor.
| |
| | |
| what you have to do to get the most "accurate" colours is enabling "exact pal
| |
| emulation" in the emulator, and then tweak the various parameters until you are
| |
| satisfied with the result. this is basically the same as tweaking the various
| |
| knobs at your monitor of your C64.
| |
| | |
| (Works if "PAL emulation" or equivalent colour generation is active)

| |
| | |
| The following are not "emulation bugs" per se, but the remaining few things
| |
| from the official buglist that did not fit into any of the sections above.
| |
| | |
| from BUGS:
| |
| ----------
| |
| | |
| - Xaw UI context popup menu for drive attach is broken if more than
| |
| two drives are active.
| |
| | |
| - Screenshots with activated PAL emulation do not deliver the expected
| |
| (blurry) result.
| |
| | |
| - When a key which is shifted on the real machine but unshifted on the
| |
| PC or Unix keyboard you are using is pressed, the virtual shift is
| |
| pressed together (i.e. at the same clock cycle) with the main key;
| |
| this could not work with some keyboard routines. If you have to
| |
| use the function keys, press the (real) shift key manually (e.g. F2
| |
| = Shift + F1, F4 = Shift + F3 and so on); this also works with other
| |
| keys.
| |
| | |
| - Using X11 XAW it is not possible to enter the disk name in the
| |
| create empty disc image dialogue.
| |
| | |
| - In the win32 port keyboard input can be garbled after issuing a
| |
| reset on CPU JAM.
| |
| | |
| - Commandline `-logfile SOME/FILE.log' fails to record logs to
| |
| `SOME/FILE.log' when resources are loaded via menu (load settings).
| |
| | |
| other:
| |
| ------
| |
| | |
| - "Also in WinVICE, "always on top" doesn't work when switched on at boot.
| |
| Frankly, I'm amazed that this isn't the 'known bugs' list already"

| - [CCS] Rick Dangerous/Myth http://noname.c64.org/csdb/release/?id=20577 (does NOT work on real c64)
| |
| | |
| "Nope, it's not a bank switching issue. Looking at the code (as you've obviously done),
| |
| you can see that every memory configuration works, as long as I/O mem is switched on.
| |
| The bug is caused by the program switching off timer interrupts (lda #$7f sta $dc0d)
| |
| without acknowledging any pending timer interrupts (by doing e.g. lda $dc0d). Sometimes,
| |
| a timer interrupt has been triggered before they're switched off, and hence, as soon as
| |
| the interrupt flag is cleared, a timer interrupt occurs, which is never acknowledged."
| |
| | |
| "A: It doesn't work on the real thing, which was confirmed by j0x in the comments ("I did this because
| |
| I was curious why it didn't always work under Vice - or on the real thing, for that matter"). Again,
| |
| the fact it does work flawlessly in CCS64 suggests that an inaccuracy exists in this emulator."
| |
| | |
| "I found out that "Rick Dangerous/Myth" fails in CCS64 v3.3 with Kernal copied from Hoxs64, which suggests
| |
| that it's merely a Kernal revision issue. It should be noted that the game works solely with Kernal Rev2
| |
| and will fail in any emulator using Kernal Rev3."

| |
| | |
| For the list of bugreports for emulators. Invest works perfect on the
| |
| real c64 without any problems.
| |
| | |
| A: Doesn't work on the real thing nor in any emulator. I suspect a disk error,

| |
| Rubi: This is only reproducable if you have virtual device traps enabled and use Autostart feature.
| |
| The intro is buggy and would probably show the same beahviour on the real machine if you enter RUN in
| |
| the wrong moment (raster line 191). Rule of thumb: switch virtual device traps off would help.
| |
| | |
| "Although this game works on both PAL and NTSC computers, VICE has problems when in PAL
| |
| mode getting past the HTL/INC intro (which is PAL compatible and works okay in CCS64).
| |
| NTSC mode will get you farther in Vice. Due to the loading routine, this game may also

| | |
| A: It crashes on my C64C, just like in Hoxs64 and VICE. This suggests an
| |
| inaccuracy exists in CCS64 because it SHOULDN'T work.
| |
| | |
| Rubi: Cannot reproduce. Works perfectly in 1.22. Is this bad as it should fail

| just like on a C64C?

| pressing space in the crack intro, or after the trainer screen

| "Here's what I found debugging DylanDog/X-Factor.
| |
| IRQs are not properly stopped when intro starts, and while calling music init
| |
| at $E000 an irq triggers using vector at $FFFE (which points at $F000, hence

| the crash)
| |
| | |
| to fix, before running:
| |
| | |
| break 2800

| |
| | |
| and then the usual missing one:

| | |
| > dc0d 7f

| x
| |

| and intro starts.
| |
| Too bad that even the end sequence loading will lead to a crash.

| It should do a jsr $1031 to set $01 and other stuff before but doesn't.

| *** [vice] Latch X and Y ($d013 and $d014) are not emulated properly
| |
| Rubi: fixed in 1.22.2
| |
| | |
| "I tested this by repeatedly printing their read values on the screen by every frame,
| |
| alongside the values stored in $dc00 and $dc01 - as I wanted to test this after seeing
| |
| a very nice raster stable routine in an old Crest demo.
| |
| | |
| On Vice, when you press and hold the space bar or any of the keys in the bottom row,
| |
| the values in $d013 and $d014 only change once, where as on CCS64 and a REAL c64,
| |
| they change every frame - which is of course what they SHOULD be doing on Vice.
| |
| | |
| The stable routine by the way, was found in the mega split-raster part in Blow Job 5/Crest,
| |
| i'm not too sure if it was either Crossbow or Vision who coded the routine.
| |
| | |
| loop:
| |
| | |
| LDA $DC00 ; Keyboard write/Joyport 1
| |
| STA $0400 ;
| |
| | |
| LDA $DC01 ; Keyboard read/Joyport 2

| |
| STA $0403 ;
| |
| | |
| LDA $D014 ; Latch Y
| |
| STA $0404
| |
| | |
| JMP loop
| |
| | |
| Doesn't matter how IRQ is setup etc. The effect relies on when you press various bottom row
| |
| keys or hit fire button in Joyport 1. Try it on Vice and then the real machine and you'll
| |
| see the difference."

| Rubi: Fixed in 1.22.2
| |
| | |
| "On emus, there will appear a strangely-patterned screen. Get yourself the real
| |
| thing or expect major vic-bugs after pressing run/stop."
| |
| | |
| "btw, aurora80% displays same on emu then on realthing, i just did that emucheck
| |
| for the fun of it, its temperature measuring via unused bits in $01"
| |
| | |
| "A: This one's interesting. First of all, in both the 85% and the 90% versions,
| |
| I've spotted no VIC bugs - neither in VICE nor in Hoxs64. Secondly, that strangely
| |
| patterned screen is visible on a C64 as well, but it disappears after a while. In
| |
| emus, a user interaction is required to proceed, and this seems to be the only
| |
| difference. This affects CCS64, VICE"

| *** [vice 1.21] truedrive emulation auto toggle problems (fixed in vice 2.2)
| |
| | |
| - truedrive emulation is switched off/on automatically when the emulator auto-
| |
| runs d64s, this causes problems (drivecode not beeing initialised properly
| |
| for example) sometimes.
| |
| - some plain .prg files do not run when autostarted with the emulator. they DO
| |
| run however if you put them into a d64 first.
| |
| - t64 files seem to have similar problems as prg

| |
| while showing the trainer screen. It does work on the real machine, but it is a

| |
| | |
| "I can only wonder how it was verified to work on the real thing. In order to make it work

| *** [vice 1.21] strange issues with $01
| |
| | |
| seems that switching $01 quickly makes VICE make mistakes in thinking what is RAM and what is ROM...
| |
| Interestingly, this one fucks up in WinVICE v1.20 at max. speed and warp mode, but not @ 100% speed.
| |
| Brings up (a seemingly long-time known bug) that toggling RAM/ROM quickly (init tune at $E000) confuses VICE.
