Did get the 2.7 SDK (20110916) working by a rather ugly trick - changed the romtag in the 1.4.5 ixemul.library and ixnet.library to say it is V50 instead of V49. Have not had any issues yet, it did even work well enough to build a recent ixemul.library from the sources available. However, the resulting libraries required dos.library 51.28. Not sure if it actually needs it or if it is a set version as a result of the 2.7 SDK I built it with.

The reason I built ixemul was to get the 3.9 SDK working, which is not happy with the romtag hack and gives hits in the kernel log for some commands.

However, I am quite content with getting the 2.7 SDK working, it was mostly fun to see if I could get any further with the most recent one :).

@jacadcaps:
Where can I find the V49 ixemul archive if I would like to build and link the SDK with that version?
