Thanks so much gadesx and thanks for the info!
Yeah I tried messing with the RAM using FCEUX and didn't really get too far.
So I took a different route and looked into the ROM for any instances where $0097 is 'read', and I found the location where it's compared with the value '07', which is Nightmare Land. Changing this to a lower number will 'activate' the WAND from that stage and on.

So looks like I got the WAND thing figured out, now I need to edit the levels. I've looked at this for a while now and I see in the PPU that the tiles are loaded there...I'm able to change the tiles on the fly, but the actual floors/platforms aren't affected. I understand that the graphics and the actual floors are stored differently in the ROM.
Can someone show me how to edit the floors, platforms, and the actual level layouts, etc.?
