Rom patching question

[gerner]

Hi, I'm trying to create the right samsh5sp 272-m1d.bin for mamedox 1.1.

 

things I've got:

 

A 272-m1d.bin rom signature 3ca75c37.

This patch: samsh5sp-m1d_3ca75c37_to_203d744e.ips

which should work.

Uips.com

 

 

Now when I patch the file the output file I get is still 512kb.

 

The 203d744e version I need is only 128kb.

 

What do I need to do get the right size rom?

 

Any help appreciated.

Assuming the checksum even matches afterwards, you'll need to split it into 4 128kb segments before applying the patch.

Figure I might as well ask here so other people can see as well.

 

How do you roll t back to the bendermike samsho5sp? Can i do it just by editing some mamedox files or would I need ot recompile?

can change the crc of file use 1.0 dat crc not 1.1 crc and hex edit
