90 min. CD-R's?

[Slider One]

Hi folks!

Couldn't find an answer for this in other posts. The thing is, I want to make all of my games self-bootable and of course there are some, which make problems just because of size.
It was possible to get Sonic 1 on a usual 80 min. CD-R by deleting the jap. voices and Ecco with the patch. But there are still some more, that won't fit, unless I downsample something.

So I thought, it'd be a much easier deal to bring them onto 90 min blanks. But I'm not sure if that's the better idea. A while ago I burned Head Hunter CD1 onto such a disk, cause I didn't have one of my usual Sony CD-R's left. I noticed, that the laser made a lot of noise during loading and I was wonderingg if that's normal with that game or if the laser had problems reading the disk.
(BTW it was an Intenso 90 min. CD-R)

So, has anyone experienced something similar, or even tried this?

Another thing. In the above case, no game data was written behind the 79:57 min mark. But that would happen, when I used the echelon method to bring such a full-size game on CD. As far as I know, Bin2Boot writes the second session at the end of the disk. In this case just the boot-sector would be behind this mark. However does the DC even have any problems reading behind it?

It'd just be ***** if I discovered at the end of a game that my DC suddenly crashes...

Any ideas, experiences?

BTW, sorry for my bad english at the moment (has been a looong day)
