Check this out! This is an actual firmware mod, and not a tuning mod.
1. WM1A/Z+
Features:
- switching the model (from "Settings" > "Device Settings")
- improvements to the sound for both WM1A and WM1Z
- DSEE HX AI (present on DMP-Z1)
- improved battery life
- hardware accelerated rendition of the UI (faster menus) How to: First install the firmware, and then go to "Settings", "Device Settings", "Reset/Format/Model Switcher",
and then choose "Switch Device Model". After switching the model, install this firmware again, in
order to fully apply the new model's sound signature.
Switching the model is not mandatory, as the mod brings sound improvements for both players.
The process of switching the model takes about 1 or 2 seconds, and then the player will restart
automatically. You can always see what is your current model by going to "Settings" > "Unit Information". 2. CHAMELEON (stock sound)
Features:
- switching the model (from "Settings" > "Device Settings")
- DSEE HX AI (present on DMP-Z1)
- hardware accelerated rendition of the UI How to: First install this firmware, and then go to "Settings", "Device Settings", "Reset/Format/Model Switcher",
and then choose "Switch Device Model". After switching the model, install this firmware again, in
order to fully apply the 1Z sound signature to your 1A.
The process of switching the model takes about 1 or 2 seconds, and then the player will restart
automatically. You can always see what is your current model by going to "Settings" > "Unit Information".
Frequently Asked Questions (applicable for both mods) - How do I get back to stock firmware?
First make sure you switched back to the original model for your player, and then just install the stock
firmware of your choice. - Do I need to be on version 3.02 before installing one of the mods?
No, you do not. - If I am already using one of the two firmware mods, do I need to first switch back to 1A or
to 1Z, and then I can install any new versions of the mods?
No, you can just go ahead and install new versions of the mods, when/if they appear, unless
specified otherwise. - If I am using the "WM1A/Z+" firmware and I want to try the "CHAMELEON" firmware, do I first need
to switch the model back to original?
No, you can just install the other firmware and that's it. Just remember that for going back to stock,
you should first switch to the original model for your player. - What happens if I switch the model, but then I don't install the firmware again?
Nothing wrong will happen. The sound might not be the same as if installing the firmware again though.
Feel free to experiment, but the recommendation is that you should install the firmware again after
switching the model.
If you were on 1Z, and then you switch on 1A and you don't install the firmware again, the sound will mainly
be the one of 1A, but it will still have slight characteristics of the 1Z sound. Same goes if you are on 1A, then
you switch to 1Z, but then you don't install the firmware again. The sound will mainly be the one of 1Z, but it
will still have slight characteristics of the 1A sound.
