The "ideal" CDTV system should boot from HD with non DMA capable...

I've traced the allocmem calls that the extended rom does, and all extended ROM calls to AllocMem during the boot are properly redirected to chipmem.

Thanks Toni. Unticking "dma capable" on Z2 ram makes "non-dos disk in drive 1" which means that the ROM allocates wrong memory type => WinUAE now makes it possible to test the new ROM!

But problem...

the goal of rom patch is to use the rom as is. Not to try to extract it. I admit I didn't try to fix the rom checksum.

In that case, I should provide a fix for extracted cdtv.device.

@bartekmalysz you found your way to EAB. several retrocomputing members here :)
