Those Bitmap video modes are coded (hardware generated) slightly differently than on CPC so you can't simply port the Graphic Datas from CPC/PLUS to Thomson MO6/TO8 without some proper recoding.
The Thomson always processes 16bits of graphical Datas in the same clocktime and 16K RAM Video per screen cycle so the more resolution the less colours. There are no overscan nor full borderless screen possibilities as on the Amstrad CPC.
Minus the lack of Hardware sprites and raster interrupt facilities (still doable on Thomson machines), the MO6 and TO8 are actually superior (in graphics) to the Amstrad PLUS Range due to the attribute based mode in addition to the 3 "CPC-like" modes, and largely superior to the Amstrad CPC due to the awesome Palette.
