new & need some fenix help

[DoctorNicholas]

Hello, I am doctornicholas. i love the sega genesis of all things, but the dreamcast has a place in my heart too (such a heartwarming story, if you want to know, i will tell you). i have been programming with fenix for awhile and i have been getting the hand of it. problem is, i didn't know the dreamcast didn't like .png's. I am using fenix 0.84b for many reasons, I heard there was a more current fenix but it doesnt not automatically load the game right away so that is the #1 dealbreaker, otherwise it would be a snap porting the game. Since I have switched over to the .fpg format, I have noticed the following.
*the enemy walking around with "swirl in a circle" while walking left and right, it makes no sense until you see it
*the player may fall through or walk through the walls randomly, again, when you see it

this didn't happen when the levels themselves were .pngs but once it was an 8-bit .fpg $%^& hit the fan and splattered grotesquely around the workspace (gross to say but is true).

you may download my project below (or above, dont know where the attachment goes yet)

p.s. does fenix 0.84b even work in windows 7 x64? im using the latest fenix pack but i know my code works in that particular fenix when i had my winxp computer, should i look for it and just program on that?
