Denise C64 mode problems!

[amilo3438]

Decided to stop testing the existing g64 collection from 2015! The reason for this is the frequent finding of something that looks like it works but is actually problematic.

As a last example: "pacmania[grandslam_1988]"... it will start and then after a while in the game the emulator will go crazy!? And the first thing is that something is wrong with the emulator, but in fact the problem is in the tested file!
(If I convert nbz from that file with e.g. -an -C -r -f options, I will get something that does not cause problems.)

So, now there remains the possibility of creating instead of looking for problems, and that in a way.... i.e. generating a new g64 from nbz using the latest version of nibconv and testing them in denise with checking problematic ones (ie those that doesn't seem to work) in vice.

-------------------

Well, this is my last test where I converted the contents of the Cyan folder (without alt versions) from the group of nbz files and tested them in denise and then in vice.

In doing so, I created a batch file to make the job easier:

for %%f in (*.nbz) do (
  nibconv %%f "%%~nf.g64"
  del %%f
)

So, that was about 90 files to test. Of those, I got 64 that work in denise (default), and those 26 that didn't work, I checked in vice3.8(x64sc) and found another 11 files that worked! I then checked those same 11 again in denise but now with new settings in disk wobble, and here are the results...

Below didn't work in denise with default disk wobble 0.5 rpm but worked fine in vice(x64sc)!

Then tested again in denise but with adjusted disk wobble to work! (wobble 0.5 rpm +- ~0.1 rpm)
------------------------------------------------------------------
bionic_commando[capcom_1988](pal)(!) .................. 0.6 rpm
black_tiger[us_gold_1989](pal)(!)...................... 0.4 rpm
crack_down[us_gold_1990](pal)(!)....................... 0.4 or 0.6 rpm
dynamite_dux_s1[activision_1988](pal).................. 0.4 rpm
forgotten_worlds_s1[us_gold_1989](pal)(!) ............. 0.6 rpm
indiana_jones_temple_of_doom[us_gold_1988](pal)........ 0.6 rpm ?(very close but not start)?
mega-apocalypse[martech_1987](cyan2)(pal).............. 0.7 rpm
metro_cross[us_gold_1987](pal)......................... 0.4 rpm
out_run_s1[us_gold_1988](pal)(!)....................... 0.4 or 0.6 rpm
rolling_thunder[tengen_1989](pal)(cyan2)............... 0.6 rpm
trantor[probe_1987](pal)..............................  0.4 rpm
-------------------------------------------------------------------------------------
--> 11 more working in vice(x64sc) and in denise but only with adjusted disk wobble

EDIT: Even micro64 had no problem running all 11 listed, while hoxs64 managed to run only the first one! (Note: 0/11 as for denise with default disk drive 1541-II ... and if it were 1541 disk drive then the ratio is 5/11 for denise!)

Is it normal that a difference of +-0.1 rpm in disk wobble can have such an impact on whether something works or not in denise!?

Emu compatibility after the test:
-----------------------------------
64/90 -> ~71% denise (default disk wobble 0.5 rpm and 1541-II disk drive)
69/90 -> ~77% denise (default disk wobble 0.5 rpm but 1541 disk drive)
75/90 -> ~83% vice3.8(x64sc)
-----------------------------------

And the rest that didn't work probably require a new conversion with some of the options turned on! (to be tested later)


EDIT: And the following 15 did not work in denise or vice! The nibconv (even with options) did not helped so it was necessary to process them with remaster-utility!

armageddon_man[martech_1987](cyan2)(pal)
avenger[gremlin_1986](cyan1)(pal)
deceptor[us_gold_1986](pal)
gauntlet_ii[us_gold_1987](pal)(!)
highway_encounter[vortex_1985](pal)(!)
indiana_jones_last_crusade[lucasfilm_1989](pal)(!)
italy_1990[us_gold_1990](pal)
jack_the_nipper[gremlin_1986](cyan1)(pal)
last_mission[data_east_1986](cyan2)(pal)
muncher_eats_chewits[gremlin_1988](pal)(!)
out_run_europa_s1[us_gold_1992](pal)(!)
rainbow_warrior_s1[micro_style_1989](pal)
shadow_dancer_s1[us_gold_1991](pal)(cyan2)(bad)
supersports_s1[gremlin_1988](pal)
zyron[kingsoft_1986](pal)

Some were recognized by the utility itself as problematic, while for some others it was necessary to turn on patching manually!

P.S.
It seems that denise is only "sensitive" when it comes to nibconv created g64 files. With the remaster-utility created g64 files, denise is not at all sensitive to rotation speed and disk wobble settings!? (then what's the problem?)
After all, I believe that there is nothing more to test or compare! So that would probably be it, as far as this testing is concerned!
