mode 2 form 1 is a cd format used for all ps1 games and probably all ps2 cd games.
ps2 dvds use UDF/ISO format.

cd games can be converted to dvd easily most of them using ultraISO. But, they don't always work. Usually though. I recommend it since the noise from the cd's (they spin really fast) irritates me. But if not irritate you then I'd say dont do it.

anyways its extremely easy to do but it appears, the information has disappeared from the net! ugh

so what you do is this:
download ultraISO portable from portableapps.
open your cd game ISO.
select file at the top then properties.
change media to 4.7(4.37)gb.
check the box that says UDF.
click set as default at bottom.
save the image as a ISO.
burn it.
