GDIShrink + Optimization - pcwzrd13 - 13.02.2019 19:57
I'm trying to both optimize and shrink GDI (using GDIShrink) files but it doesn't seem to work a lot of the time. If I optimize the GDI first, it usually can't shrink the GDI. If I optimize it after shrinking, it has a better success rate but a lot of the time I'm left with the GDI file and a 690KB raw file. I'm guessing the DreamShell optimizer wasn't created with shrunken GDIs in mind. Any chance someone could look into this?

make screenshot your folder with GDI after GDIShrink and content of *.gdi file

Before or after optimizing the GDI?
RE: GDIShrink + Optimization - megavolt85 - 14.02.2019 17:26
Before

it's after GDIShrink and before optimize?

Yup

why need GDIShrink? size of image stayed the same 1.2 GB

Oh woops. Didn't even notice that. It doesn't work on some games apparently. Here's Wacky Races. GDI Explorer won't open it so I can't show the contents of the GDI.

show the contents of Wacky Races (US).gdi file

GDI Explorer just gives an error when I try and open it. Here's the contents in a Hex editor though.

this image alredy optimised
GDIShrink create optimised image, but violates the GDI specification, after track03 there must be one raw track
and need patch TOC in IP.BIN

Hmmm, interesting. Will this cause any issues?
Also, out of curiosity, what does optimization actually do?

I do not know if there are games that check it

remove header, ECC, EDC from bin track, BIN track transformed ISO track
optimization is conversion bin tracks to iso

Good to know! Thanks! :-)

For pcwzrd13 (and anyone else who wants an answer to this question): I've found that using RebuildGDI to shrink the GDI, and then separately optimising it will result in a usable copy that will almost always run fine.
(The only exception I've found was Metropolis Street Racer which would black screen after the first fmv).

I'm guessing they don't work either, yeah?
