PS2dumperV2で吸い出すとeromが出来ないんだっけ
逆かなんかそんな感じ


ROM1, ROM2, EROMも必要?
If the console is warning you about not having these files,
do not panic, all you need is the main ROM0 (the 4,096kb main BIOS file).
You can dump the ROM1, ROM2, EROM from your own PS2 console,
again guides and tools are on the internet, use www.google.com.

要りません。
