@Mindflower Just thought I'd stop by to say this is looking fantastic. Every time I check the forum for this project, I get more and more impressed with the progress you are making.
I'm curious though, most of the Metroid hacks I see alter the player sprite in some way - But, the jumping pose is usually the same (one leg is kind of pointing backward while the other is pointing down). I know this is due to a limitation with how the base game works (sharing jumping graphics with running graphics). I was never able to overcome this limitation myself without methods that will not work on original hardware. It was always frustrating because I thought the pose always looked a bit awkward. I'm wondering, have you seen any discussion recently at Metroid Construction in terms of attempting to alter this behavior? I think the look of both legs being crouched up (similar to Super Metroid) is a more dynamic look. But, I know it would also involve separating running and jumping graphics. I haven't seen a solution yet for Metroid that can be achieved exclusively with a .ips patch. I'm interested to know your thoughts.
BTW - really impressed with the blizzard effect and parallax effects!
So, funny timing. P0ZN0 just brought to my attention a hack that was just released on October 18th. It looks a whole lot like that pesky jump pose issue was solved somehow. @Mindflower, I'm curious if you've seen this.https://www.romhacking.net/hacks/5463/
