Problems with some CD32 Games emulation
 
Hello folks,

Using the CD32 Emulator ( that came with the Idefix package) and/ or the Squirrel CD32 Emu;
I currently have some problems with Impossible Mission,
Pirates! Gold, and Zool etc.
The main problem is, that the intro animation sequences won' t work properly; the screen gets corrupt with some pixel mosaic and the sounds very distorted and corrupt.
Those games worked ok with tge intros/ animations before.
However, there are two main changes in my hardware configuration: before I used my drives with A4000s internal ide bus; now Im using the Fastlane Scsi card only, and thought my setup is propably quite ok.
The second change is the removing of that buggy old A3640 processor card and replacing it with tbtorro' s A3660 card. I think the årocessor is working mainly ok.

Any ideas for configuring/ optimizing the cd rom file system for Scsi-2 ..?!
I did install my cdrom driver with the cdrom installer that came with the OS3.9 cd . However, it seems that installer doesn' t allow any more accurate fine adjusting of the driver; and the Cachecdfs dosdriver file is a little too complicated for me.
How to properly enable direct Scsi commands, for example ?!
I have another question, regarding the CD32 Emulator package/ program ( Idefix/ Cachecdfs):
The program has an option to use ( Commodore' s) 68040.library. Would it be ok to fool the program using really a 68060 library instead ?!?
I succeeded in that by renaming the lib files accordingly, but guess I would be a little on an undiscovered land by doing this ?!
Anyone there who would like the aCD32Emulator program( s) optimized/ fixed for 060 Amiga users ?

It seems that animation files named with *.xl are not working. Those .xl files were seemingly used by Microsoft. Which would be proper viewer app to test those files on wb ?!
Strange, is it the limited speed of my old Scsi cd- r drive (4*); or some stupid incompability with the 060 that's causing my problem ?!

I can't offer any help as I don't use any "CD32 Emulators" under emulation.

...but Pirates! Gold works absolutely fine when running via WinUAE --> Quickstart CD32 and mounting the image directly within WinUAE :agree

You can replace real 68040 lib by the 68060 version (also called 68040.library) and put 68060.library in LIBS: too.

AFAIK 68060 library isn't here to boost the performance (apart from enabling the "new" branch/superscalar caches), but rather to implement scalar instructions that were removed from the 68060 because they were seldom used. They're emulated instead (most famous: MOVEP). So if you don't put the 060 lib, and treat the 68060 like a 68040 it may work to some extent, but also crash if one of the games uses a non-implemented instruction.

I found that the OS3.9 Cachecdfs to be the most compatible. Had games not loading or crashing. Using that cachecdfs, never had issues with any game running via CD.
