Just saw this. Outstanding!

Great job, NeverLies.

Did you find the "magic" 0x10000 / k in the ECU disassembly?

Epifan, can you upload your latest release ?

Ok, that's great!
I'm change XML description to support increment axis for 2d maps. New version will be upload soon ;)

Just right ! :D :D

What is the ROM revision you are working on Khaos ? On mine (A4RN200H), routine to manage 2D maps is located at 8C64. It first start with a case like test to handle all kinds of 2D types.
First case is for 2D map where (type & 0x80) = 1, so 0x80, 0x81,0x90,0x91. This is the case we want to study ;) It goes on to treat 0x8z / 0x9z and then 0xz0 / 0xz1.

I've been using an A4SG900C for all of my work.... all of my disassembly files and notes are on another computer, though, so I'll have to look... I have found the map processing subroutine, though.

I just ran out of talent about 6 logic levels down into the sub. :)

I'm upload new version of ecuEdit that support increment axis. I'm can't find correct "increment value" in my ECU so I decide to adding 2 diffrent way to describe increment axis: by "increment value" from ECU and by constant increment value.
