CD-I 350,60x,205/910 issue

I've spent the entire day looking for the problem on Mini MMC based players. I cannot find a solution for the problem. I've rearranged the FCT many times, done traces on the Balboa version of Frog Feast, studied many FCTs from different games and even followed the code through the Balboa sources.

The image I get, on my CD-I 605, is 320 x 224 or 256. Frustration is setting in as there is no clear answer or any direction on where to search for a solution. A 320x224 ot 256 mode is not listed in any documentations that I've seen.
