It's maybe a stupid question but is it possible to replace ntsc cic chip d411 with pal one d413 to make ntsc game run on a pal snes? Would it work?
I've tried to solve it with FX converter aka honeybee but I just get a solid black screen... Any idea's are welcome...
Thanks.
It's also possible for the game to detect the system's region, and could refuse to run. I think it was Puzzle Bobble that had a screen for when that happens, but I'd expect a black screen would be more common.
Memblers is right. Some games need both CIC trickery and a 50/60 switch. Either they explicitly check for frame length or they use raster effects that fall out of sync on the wrong TV system.
Actually, games just read a register that will tell them if the PPU is running in NTSC or PAL mode. You don't need anything fancy to detect the video mode on SNES. Assuming a game doesn't do that then all that is stopping it from running is the CIC. Though SDD1 and SA-1 custom chips actually do their own region checking/lockout.
I suppose a Game Genie or similar device could be used to de-protect it, by reversing a branch condition in the code. That requires a bit of investigation, and might not apply in this case.
