For svcchaos, use this command:
p_dec 1

and this P rom:
269-p1.bin  32mb crc(432CFDFC)

and you should get this:
269-p1d.bin 32mb crc(7DB9C3BB)
*note that only the first 7mb are required
** note that this has been scrambled so that it will work with Halrin's bankswitch code

For kof2003, use this command:
p_dec 2

and these P roms:
271-p1.bin   4mb crc(b9da070c)
271-p2.bin   4mb crc(da3118c4)
271-p3d.bin  1mb crc(59d376da)

and you should get this:
271-p1d.bin  9mb crc(2636E0D5)
*note that only the first 7mb are required

For mslug5, use this command:
p_dec 3

and these P roms:
268-p1.bin   4mb crc(d0466792)
268-p2.bin   4mb crc(fbf6b61e)

and you should get this:
268-p1d.bin  8mb crc(3B0C2E7D)
*note that only the first 6mb are required
** note that this has been scrambled so that it will work with Halrin's bankswitch code
