How can I add extentions into TinyCore-4.7.iso

[funcvg]

I want to add locale.tcz font.tcz into TinyCore-4.7.iso,which was downloaded from offical web.
I use UltraISO to add locale.tcz font.tcz into /cde/optional of TinyCore-4.7.iso,then save it.
I test the iso in VirtualPC 2007.
VirtualPC boot ,but stop at "tc@box:",can't load X GUI .startx do not  work,there isn't the command.
In /mnt/sr0,there is nothing,but there is the files in TinyCore-4.7.iso when boot from offical iso.

I want to make a cd  to boot TinyCore-4.7 with the locale and font ,which can make it possiable to  display the non-english files in the disk.

When I copy the files in the iso to the root of local disk partion (hd0,0)/,X GUI works with grub,rename cde to tce ,and add extentions to  (hd0,0)/tce/optional,locale and font work.

Why I can't modify the offical iso with UltraISO to add extentions into /cde/optional?
Maybe,the modified iso can't be mounted to /mnt/sr0.

Please don't use those ISO modification programs. Unpack and create the ISOs natively from linux.

Saves you from a lot of hassles like that.

And do not forget the boot part.

ezremaster should work with all 4.x versions of Tiny Core.
