THE PRINCIPLE

I use this hacking method with my PowerMystic.
MacOS8.6J is installed on my PowerMystic.
I have not tried this method with Mystic without 640x480 + OS8.1.
But I heard that someone succeeded.

Open "gusd" resource of 8.1 "system" file.
You can see many sets like "00xx 00XX".
This seems to define the combination between machine-ID & boot-process.
The former seems to be ID-No.(hex), the latter seems to be boot-process.

ID-No. of Mystic without 640x480 is 99.
But 99 is officially assigned to LC580 series.
Then ID-No.99 is combined to LC580's boot-process.
You should combine it to LC575's boot-process.
ID-No. of LC575 (also Mystic with 640x480) is 72.

99 decimal is 63 hex
72 decimal is 48 hex

You can see "0048 000D" at "gusd" resource.
"000D" seems to be a LC575's boot process.
Then change "0063 0015" to "0063 000D".

That's all.
But I don't guarantee.
If you try this, please do at your own risks.
And please report here.
