1541 (Un)Compatibility problem in 2 latest demos

iAN CooG/HF · Post by **iAN CooG/HF** » Sun Jan 04, 2004 12:16 am

"Anyone" and "Game Over" by FLT+Crest have a particular loader that prevents CCS 2.0b (feb'02) from loading part 2, even using "normal" loading of main part.
Use Jiffydos 6.01 Rom to work around, I've been able to watch the demos to the end only this way.

Hint already added to CSDB entries comments:

Thanks, Ian. As mentioned in the previous post, some revisions of the C64 Kernel ROM are better suited to certain games/demos/cartridges than others, but using Revision 3 is generally recommended (bug-fixes).

In these 2 cases, rev 3 kernal does not change things. You have to use JiffyDos.

Thanks for the information, Ian.

I think also DolphinDOS is used for some other reason, so certain DOS versions are suited to some particular games/demos/cartridges.

The C64 Kernel ROM seems to raise quite a few issues, but luckily these seem to be isolated, unless anybody knows of any general pattern of C64 Kernel ROM compatibility issues/recommendations.

I have also noticed that the CCS64 Fast-Loader is not compatible with IFFLS, as used in recent NOStalgia cracks.

Which game? I always use Return to load the main file from F9/drive 8 (so in "fast" emulaton) and they load all correctly. I always use alt-e/1541 status on to see if drive is working and nothing strange happens.

I also noticed that CCS 2.0b (feb02) can't run the CART version of Serpentine (or SerpentiLe, call it what you prefer

)
I've ripped it and made a working (and +1 trained) standalone PRG, tested with all kernels and speeddos/jiffy/dolphin etc.
Please test it in CCS 3.0 as I don't have (and no intention to install) DX9.

Support for the Serpentine cartridge has only been added to CCS64 V3.0 BETA. CCS64 V2.0 BETA is no longer developed by Hakan.

I think it is IFFLS V3.4 and later, but definately certain versions of IFFLS.

This is not a fault of IFFLS, nor of CCS64, since fast-loaders are always developer-dependent.

I know. So I've made Serpentine.prg playable also in ccs 2.0 because of some "interfering" JSRs in CART code

CCS64 V2.0 BETA is no longer developed by Hakan.

No problem. I'll continue using it. Tested 3.0 at office and didn't liked it.

If it runs on a real C64+1541, it is CCS64's fault.

As I mentioned, fast-loaders are always developer-dependent; therefore, programs that use specially-developed fast-loaders (like IFFLS) should be run in "Normal" C64 mode. IFFLS games *do* work with CCS64, when they are Run (Normal), not Run (Fast). Therefore, there is no fault.

Your problem you are having with certainloaders is due to the fact hat your 1541.rom is ALSO an old revision. Try using the one that comes with VICE (latest 1541 ROM) and the stuff should work.

I can't confirm, but still I'm using CCS2.0b. Tried now with rev3 kernal+c1541.rom from Vice - and yes, the rom is different, like it was patched - and at least the 2 demos above don't move from track 18 (see disk activity using alt-e). Only using Jiffydos roms the parts are loading without problems.
