I decided to reinstall Hermes 222/223 and double check what I was doing as I went along. I used the v4 cIOS installer.
249 is installed and works great. 222 was installed as a merge of 37 & 38.
223 as merge of 60 and 38.
37 is rev 3612
38 is rev 3610
60 is rev 6174
I can take any game that works with 249, change it to use 222 or 223 in USB Loader GX settings and it ceases to work.
Anyone have any ideas or suggestions please ?
