Tokyo Ex Racer 2 Save Game Patch.

Just *cough*aquired*cough* the TXR2 save game patch and I'm kind of confused.
Whilst the game was released in a cdi format, the patch doesn't contain a standard ppf file, instead it contains 6 files :

1st_read.bin
audio.raw
cygwin1.dll
Ip.bin
Ipins.exe
mkisofs.exe

Also NO readme file
I'm guessing that I need to convert the cdi to iso and then insert the files b4 burning, but the prompts I'm getting whenever I use the exe files have me scratching my head.
Can anyone help me out with the proper procedure with this, or can refer me to a place where I can find it out myself?

Cheers,

PMB
