I think that there was already such an option ("Disc control").
i have a sugestion to uLE dev team to add option like "Stop reading disc after launch other elf file".
(just if the other elf doesnt loaded from the disc , just like my case)
maybe the algorhytm like this :
I don't know much about uLE's options, as I have not really looked into this.
I only heard that that option was supposed to stop the disc from spinning or something like that.
You can change the modchip, but it's difficult to, and you must be very proficient at soldering (The solder points are very small!!).
Is it posible to change the modchip ?
If posible what chip that support dev1 booting ?
As for modchips that support DEV1:
I know that the Matrix Infinity was known to be one rather famous one, and that probably many of the "modern" modchips that are not cheap clones will probably also support DEV1 booting.
I have a "cheap" solution for you: Once OPL had loaded, just eject the disc.
The Mechacon will detect the drive being opened, and stop the drive rotor. Games won't be affected, as they do not attempt to access the CD/DVD hardware directly (Disc status is emulated by OPL).
As long as you didn't tamper with the sensors (E.g. For a Swapmagic setup), the PS2 will stop the drive whenever the drive door has been opened (This is by design).
