Does anyone know how I can make the ZANAC-EX rom image work with the ESE-SCC Sram cartridge ?
I can use Konami games, and other MegaROMS, but Zanac-ex does not work, any ideas?

Did you rename properly the file extension?:
ASCII 8K: *.8K (ascii 8K bank)
ASCII 16K: *.16K (ascii 16K bank)
KONAMI SCC: *.SCK/SKN (SCC Konami)
KONAMI WITHOUT SCC: *.KNM (Konami normal)
R-TYPE: *.IRM (Irem)

Tried most switches - not sure which to try - that is why I have asked  |

If I understood Ivan correctly you need not use switches, but rename the ROM file to a file with the appropriate extension. Apparantly the ESE-SCC ROMloader uses he file extension to determine the mapper type.Did you give it a try already?

As you were told in #msxdev, it's ASCII 16K.

i set the extension to .16k for a standard 16k ROM cartridge - but no success 
Is there a decent copy of the image to download? Is there a version that will work with the Sunrise CF ?
Thanks for you help

I become a little worried as people suggest that our CF-interface should be blamed for software that doesnot seem to work.

I'm not sure if cartridges like Ese-SCC, MegaFlashROM, MegaRAM, Zemina carts, etc can load all ROMs.
Maybe some ROM dumps need to be patched to work with them.

I'm referring to ROM files downloaded from Internet to use with emulators.

No one was blaming the Sunrise product - it works fine I have a disk copy of Zanac-EX that will not work with the CF product - probably because the way it is hacked, any suggestions ?

It's not the fault of CF, it's because of MSX-DOS2.
MSX-DOS2 has memory handling routines that do allocation. Your Zanac-Ex crack access the Memory Mapper through direct I/O, screwing up the DOS2 memory handling routines, crashing the MSX.
As sunrise said, use a program called map.com (and sometimes map2.com or mapit.com) to disable DOS2 memory handling and it will work fine.
Any DOS1/Disk-BASIC1 program that uses the memory mapper will get problems running under DOS2/Disk-BASIC2 without disabling the DOS2 memory routines.

AFAIK, ZANAC-EX is a 32 KB ROM with no mapper. It should run fine without any switches, booting it from ESE-SCC or RAM directly.
Perhaps the problem is that the cartridge has its own copy protection, but it shouldn't be a problem using ESE-SCC. For example, some Konami games test if they are beeing booted from RAM, and if so, they hang.
Kind regards,
Ed R.
