Hack is done!
There is one or two rooms I'm not superhappy about but overall I'm pleased with the result and it's a definite improvement wich is what I set out to do. I just need to do some final testing to make sure I havent overlooked anything. I like to test my projects on various emulators and screens (computer monitors, tvs, phones) to make sure the palettes look ok.
Oh and as a bonus I decided to include the unused "goblin room"-music in this hack. It will now play in the Sphinx room where I found it to fit very well.
If tests are good I should upload it to the site this week.
