To what extent did you write inline assembly in this? I feel like there's some nasty tricks going on to prevent disassembly with IDA.

Patching the tricks is ok. They should stand out like a sore thumb anyway. Also, I forgot to tell in the description that this is a VM crackme.

That was a nice one Kirjava. Surely confuses IDA, but not for the experienced ones. Fun to play with on a weekend. Keep them coming.

I know patching wasn't allowed, but it help'd me to understand how Ollydbg works. Also finland ftw :)
