Building Rom using MKROM

[rpc]

Can anybody please help me to build a rom? specially to the XDA-developers, thanks in a million...in advance.

My question is:
1. Do i need a base rom(no program included) on the cfg/(rom.nb1)? is it necessary ?
2. what is the maximum files i can put in the files/ directory? that will be splited by mkrom, i know it is depending on the version since 3.17 the maximum for all files is 5 M. how about other version. 4.01,4.05, 4.10 and 4.16
3. when i run the bash setup.sh nk.nb1(4.05), using parameter for 4.05 i get a message "!!! your rom is not known to me: md5:fb9e70c5786f08e4db6db7c184c59704" is this normal or it is not define on the splitrom.pl ?
4. what kind of editor did you use for building a BMP file with 16 bit, I tried to use adobe photoshop 6.0, but i can not seem to save it as 151 k, the option is only 24 bit and 8 bit, if you can give me a site where i can download it , i will really apreciate it.

Thanks for the Help..
More power to the XDA team
and
Welcome TMO 4.16!!! (which i think no diff with 4.10) :P

1. yes you do need some kind of rom to start with

2. you can check using perl splitrom.pl yourrom.nb1 -ob <your bmp offset> | perl calcgaps.pl 0x3ffff and add the sizes of the holes.

you have to figure out where the bootsplash is for your rom. ( for new roms this is most likely 0x81ec0000 )

3) there is a list of 27 roms I know about in splitrom, if I never saw your rom, the signature will also not be there.
btw, what rom do you have?

4) I think we used photoshop for that. ( Peter Poelman knows more about that )

thanks for the reply XDA developer Itsme,
but how can i build a baserom with the rom i have, I have a ROM 4.05 which i created in jeff's kitchen? or any site where i can download the base rom 4.05?

I have a ROM 4.05, 4.10 which i get from jeff's kitchen and also the original 4.10 TMO. regarding the signature of the ROM, i read your splitrom.pl and i found out you 27 list of roms, but i didn't find that signature "md5:fb9e70c5786f08e4db6db7c184c59704" is it because my ROM is not base ROM?
my param is ;

wincever=4
start1=21740000
size1=0040000
start2=003c0000
startbmp=81ec0000
startop=81b00000

I'll still try to use the photoshop, maybe i miss something there.

Please correct me if i done something wrong with my commands.

I have Perl 5.8 and cygwin, installed in windows 2003
then make the path for perl/bin and cygwin/bin

then i copy all the things i need to build a rom in one directory including nk.nbf(with jeff's 4.05) and mkrom tools(which i got from the demokitchen)

i run "perl setup.sh nk.nbf" to extract the bootimage.bmp and rom.nb1 to cfg/ directory

then i dump "dumprom -4 -d files -q nk.nbf" to extract all files in files directory

then i convert "perl fdf2reg.pl files/default.fdf cfg/default.reg"
"tr -d "\0" <files/initobj.dat >cfg/initobj.txt"
"cp files/initdb.ini cfg/initdb.ini"

then in files/ directory i delete all the windows files i leave only the program with the dll i wanted to add in the rom like total commander, file commander.. etc...
(I compare it with the original files of WM2003)

then i run "bash mkrom.sh out/out.nbf"

but i got an OVERLAP message on the screen
and also the same message like i told you before "Your rom is not know to me"

Please Help me with this because i want to build my own rom according to the program i need.. and many thanks.

split rom does not recognize romkitchen roms, since they vary too much.

you should use an original rom, not one from the romkitchen.

the overlap means that somehow the params file was not correct.
or maybe you just tried to add too much files.

Thanks Itsme, thats why splti rrom can not recognize the ROM I have, I'll try to search for the base ROM in the forum, or can you give me a site where i can download the baseROM, I think that's why I am having a OVERLAP because there is a added program on my ROM, XDA-Developers File1 and File2 is duplicated.

It answer my question regarding the ROM i have, thanks a lot man you really a good help.

Now my only problem is to find all the base rom so i can start cooking some ROM. :cry:
