I understand that aspect, i also didn't say anything about blindly copying.
How would one apply the map switching routines to other .bins, I guess would be a more appropriate question.

Good afternoon, thank this forum for the great information that there is reverse engineering.
I am doing my map switching, I can find several maps well, but problems to find the KFZW in the address 812120.
Searching and comparing several projects I found the code that refers to the KFZW, but I don't understand the "mov r13, # 311Ah"
For me it would have to be "mov r13, # 204h"
204 * 4000 = 810000
810000 + (r12 value) = 812120

311Ah is the rl_w axis of the kfzw 0x1311A obviously
its the short addressing method for the maps stored in 204 205 segs
and thats why you cannot simply create a new kfzw maps outside
math routine (0x78B8) should be also moved and changed to respect new segment addressing

Is there a way to move the map to the end of the file?
I understand that R12 is the beginning of the map, r13 is axis, r14 and 15 are the variables of each axis.
If I just modify r12 to the new address, will it work?

only if you place new map(s) in 204 205 segments (if you can find a free space there  ) OR in the ram area 380000-384000 iirc i didnt try the second option imo its a more complex way to solve this |

I want to do this in AMK too but its a long way and I didnt have Ida pro for now. Unfortunately there isnt a description of function in bin file so hard to find what we need change directly in bin file. |

I start to diassemble code from m box ori and with map change and compare.
Please tell me what mean if in ori we have for ex. :
mov r12, #0F28h
mov r13, #206h
and in mod file is changed for :
mov r12, word_BF62
mov r13, word_BF6A
I want to understand how it work and how to read this.

It seems ORI code point to a fixed address (in flash) and MOD code point to a ram address whose content can be modified dinamically elsewhere so you get an effective address switching method. IMHO. Haven't really thrown a single second looking at it on IDA, but from the snippet you posted... this is my assumption. Regards, |

Did anyone ever patch this multi-map routine into the 002 version of the M-Box bin? Looking to combine these features with the 5120 hacked bin and I'm worried about potential differences between 001 and 002.
Thanks!
