Is there a RAM-disk that does not need to be in ROM and supports more than 64KB?

Here are two applications I know of that create a virtual floppy disc drive using the extra 64K of RAM:


Once they're installed, you can format the virtual drive and use commands such as SAVE, LOAD and CAT in the same way you would when using real floppy discs.

It's probably simpler than the 2 tools listed above but depending on what you want to do, there is also a small set of RSX that I wrote a long time ago. ;D

MSAVE,PtrRam,PtrExtRam,Size
MLOAD,PtrRam,PtrExtRam,Size
MLDIR,PtrExtRamSrc,PtrExtRamDst,Size

Basic save/load/run:
MBSAVE
MBLOAD
MBRUN

MPEEK,PtrExtRam
MPOKE,PtrExtRam,Value
MDUMP,PtrExtRam

PtrExtRam=&0000 to &FFFF (additional 64k)
PtrRam=&0000 to &FFFF (main ram)

Rhaaaaaa

thanks for these hints. 

It seems all those tools are limited to 64KB. I am looking for a RAM-Disk that e.g. supports a DK'tronics compatible expansion with 256K or more.

I can't test on my real CPC+, but with Winape , in CPM, a 512KB Ram disk is recognized without any ROM for it.  But the CPM needs to be patched.

 Under Amsdos I don't know a way to do this.

I think Silicon Disc have rom with rsx for 256K of ramdisk.
In STARS, TREK is better than WARS.

Eto wants software on disc (not ROM) to support a RAM disc greater than 64 KB.
Personally I would patch one of the RAM discs for 64 KB extra memory. 
But the question of the 1st post remains.
