clone cd + ###ne + modchip

[dad]

I live in Australia. I have a modded psx 900x (pal) and all the games I've backed up (100%) using ccd are pal also.
I tried to play a fully working pal backup game written at 8x in a unmodded ###ne (pal) and was asked to insert a format disk. YEAH I know, need a modchip to play backups.
Researching thro' various forums I learnt that the psx has a multi-region bios where as the ###ne has a single and will only boot disks from the country of origin (###ne pal will only boot pal disks).Should my disk have booted then? or is the case that ccd does not copy the booting process and the chip is needed for this? If so, would it be fair to say that ccd does not deliver a true 1:1 copy then?
So if someone would be kind and willing enough to shed some light on my curiosity in some detail rather than the usual short reply (You need a modchip to play backups) that I usually see in past posts, I would greatly appreciate it.
- THANKS IN ADVANCE -
P.S Is there another way to play backups in the ###ne besides a modchip, like a bootdisk or something?
