Where to begin... Well, I ported S3K's layout format to my S2 hack. I thought I had a pretty good idea of how it all worked, and have been able to track down and fix every issue encountered (outside of a recently-discovered bug in WFZ I'm sure I can fix). All but one, anyhow. MCZ's background now loads incorrect blocks as you progress through the level. I've been unable to find any code remotely related to layout reading outside of what I've already changed, so I'm lost as to what the problem could possibly be. It's not something I've encountered with any other level, and it appears even in otherwise-stock S2. That said, making MCZ use the 'standard' BG deformation instead of its own doesn't seem to incur the bug. I'll add some pics or a ROM when I get the chance. So, erm, yeah. Can anyone spare a little help, here?
