Hi there, I got my hands on a weird cart that is an unofficial Zanac port from FDS version that was put on a real cart. The symptoms are rather unusual:
1.When you defeat any boss, the floor just gets garbled, looks like it exploded (this doesn't happen in the original game though as I checked it)
2.Whenever you fight a boss and the timer runs out, the game just freezes completely (in the original game, when the timer runs out, it just disappears completely and you fly away from the boss and continue the game)
3.After you complete level 4, the game doesn't progress any further at all, although it should (in the original FDS game, there is a loading sequence after completing level 4 and you still go on)
Since these issues occur, I got this cart for means of potential repair. I checked all the logic chips, although nothing seems to be obviously broken as I checked everything, so unfortunately I think this cart is just "a bad port" and nothing else can be done. Although I still opened this thread and maybe there is someone smart enough that can point out some "issues" and maybe there is some way to reprogram or retrace this cart so it can become functional as it should
Here is all the info I have for now:
I put all scans and dumps into an attachment here as ZIP file, if something doesn't work then please let me know
I also put all photos right here below for quick preview:

I don't have any photos of the symptoms yet as the cart is currently disassembled, although I can take them if needed. Please for replies and potential help. Thanks in advance!!
