Title: [NES][RAM MAP] 3DNes Excitebike Profile needs your help[SOLVED]
Post by: geod on May 23, 2018, 08:40:21 am
Hello friends,
I'm Geod - the author of 3DNes emulator:
https://geod.itch.io/3dnes
Currently i'm working to create a 3D profile for the nes game Excitebike. Link to the topic:
https://itch.io/t/232355/excitebike-heavy-work-in-progress
In order to do it, sprite processing isn't enough.
I need info about the distances between bikes and the ground. I already looked into:
https://datacrystal.romhacking.net/wiki/Excitebike:RAM_map
but haven't found the needed info.
So here i would like to ask the help from you - the community.
Any additional ram info is welcome and appreciated.
Thank you in advance.

I made an editor of Excitebike a few years ago, so I had to disassemble the ROM. There's a single PRG bank, so it was not too long. I don't think I could tell exactly everything pertaining to the biker's AI or sprites placement, but I guess it could be a good starting point. Also, the RAM map, with my own knowledge of some offsets. Far from complete, though.

Thank you for the information. It's still not enough in my case because i need state info of all bikers no only the controllable one. It seems that  i have to find another way around it :(.

Thank you again for the help. I end up study the ram map myself and finally able to create the 3d profile.

The link you posted is of a speed-run. It doesn't seem to contain any 3D footage.

And as you seem to have solved this you should update the topic information. ;)
