Invisible platforms in super mario
Graphically the game looks right, but I have some invisible platform and some hole in walls here and there (example:http://imgur.com/Jg5iUHK). I'm not sure what part of my emu is wrong on this. Could this be a cpu bug?

Does your emulator pass all the CPU test roms?yanos wrote:Could this be a cpu bug?

Yep. except some timing issue that I'm currently trying to fix.
Re: Invisible platforms in super mario
Hmm... perhaps PPU mirroring is incorrect?
Re: Invisible platforms in super mario
I doubt it since if that's the case, EVERYTHING would be wrong. But it's only every so often here and there. It's quite puzzling

It looks like the status bar at the top is cutoff. Does the status bar look correct normally except when this happens?yanos wrote: I doubt it since if that's the case, EVERYTHING would be wrong. But it's only every so often here and there. It's quite puzzling
Re: Invisible platforms in super mario
Double check the RAM implementation, that everything is mirrored correctly, and that addresses are correct.

Re: Invisible platforms in super mario
I'm unsure about the "platform", but there's something wrong with your sprite 0 hit detection code.

Yeah, my sprite 0 hit detection is not is bogus, it's just not the priority right now. I'll check my ram implementation and mirroring code in the PPU.
