Hm, maybe I was a little too fast with my assumption. I thought that the MegaFlash could also replace the Lower ROM, but it seems that it doesn't. So, the Firmware ROM ( X-MEM - CPCWiki ) won't be usable (which initialize ROMs 0-31).
How about using UniDOS as an IDE interface driver? Which interface do you use?

I prefer cubemdos because most easy to use... I'm using a cpc6128 and  a megaflash that could be able to replace the rom 0 (but not the dos rom 7) . But seems that cubemdos and 32rombooster rom can't live togheter ...

Don't know about the Problem, but instead of using the old Booster Rom you could try the more modern Firmware Rom 3.15 / 3.16?

Can you tell me more please?

Interesting! I don't know, but has been CP/M prepared in the past for such kind of things (mounting activities) or did you change something?

CP/M Plus natively supports devices up to 16 MB. In addition it's the only native CPC OS which allows to use the full power of the Z80 - means use 2nd register set. This can speed up applications up to 30%-40% compared to a Z80 which does waste the 2nd register set for f.e. interrupt handling like the native OS (you see, they worked on 8080 before). Since CP/M 2.2 is using the Firmware as BIOS it also doesn't allow to use the genius 2nd register set sadly.

I was thinking more about "mounting" a device during runtime. I understand that a floppy or drive will be recognized and mounted by CP/M during the boot process, but it seems that is also possible after that process; some kind of "hot-plug-in". Tables / internal device lists have to be adapted... ? (It's obviously that I don't understand the CP/M system architecture )

I've tinkered a "rom-box" and can confirm the rom version works.

I forgot to mention: "...for the uIDE interface".

Hi,
i think @ervin is right, the decompression is overwriting the stack.

To solve your problem try to set the size of your image to 0, 0 (image size by default) and no args after image:
$(eval $(call IMG2SP, CONVERT        , img/transition.png, 0, 0, transition, , ))

I have done this some weeks ago and the size file was OK.

I can confirm that works! Thank you!
