Using same Kernel.bin across disks

[xLostWingx]

I was just wondering if I can continue to use the modified Kernel.bin from Disk 1 that I've made for Disk 2 and 3.  It seems to work fine, but I haven't tested everything and I was just checking if there is a 'best method' for this, or if swapping them as-is is fine.  PSX version.

Edit:  Thank you Gemini.

All disks are virtually identical, so it's safe to use the same files across all three of them, KERNEL.BIN included.
