[Terisa de morgan]

Could we do it in the other way?

It should work the other way around, but I haven't tested it at all:

Edit: Wait until you see which home screen you get, don't apply the patch if you don't need it.

`Enable new home screen` (paste into libnickel.so.1.0.0.patch)

Spoiler:

<Patch>
patch_name = `Enable new home screen`
patch_enable = `yes`
# HomePageController::newHomeScreenEnabled() --> True
replace_bytes = 736894, 30 46, 01 20
</Patch>

patch_enable = `yes`
#
# Value displayed on both menus
replace_string = 9D2C3E, `30 mins`, `20 mins`
# Actual value used for sleep menu
replace_int = 80A8F6, 30, 20
# Actual value used for power menu
replace_int = 80AA62, 30, 20
</Patch>

Thank you. That would do very well.

Thank you very much. I think I'm going to try it this evening and I'll be back here with the results.

"Enable new home screen" patch worked on my H20. After upgrading to 4.3.8842, I did not have the new home screen. Enabled it in the patch and installed it, and voila! New home screen. Thanks.

[JSWolf]

I'm going to try this tomorrow. I don't have time today to give it a go. But the patches are good to go though. So all I have to do is install the firmware, check which home screen I get and if it's the new one decide if I want to stick with it.

GeoffR, is it possible to add these patches

Remove system fonts in Reader list
Remove non-system fonts in Reader list

thank you very much for your work

[Martina Schein]

GeoffR, booth patches (`Enable new home screen` & `Disable new home screen`) are working fine on our H2O and Glo.

Thank you very much.

@GeoffR,

Nice work with the 'Enable/Disable new Home screen' patches

[mbovenka]

Great work Geoff

I'm having an issue with the `Custom Header menubar - reduce height by 33%` patch, though. It applies, but doesn't seem te work; the menubar stays the default height. Same with the 50% one; I tried that one too.

[Terisa de morgan]

I've tested Enable home screen and it works well, thank you. I think I'm going to keep it at the moment. Thank you very much for this patch and for all your work in every FW with them.

GeoffR, as a fellow inhabitant of Zealandia I really appreciate the late hours you keep to bring us all this - by my time your last post was at nearly 3am!

Many, many thanks for your work.

It's probably me you need to be talking to for this patch.

Let me double-check it myself on my H2O and I'll get back to you.

In the meantime, a couple of basic questions:

1. Are GeoffR's patches the only patches you're using to patch the nickel file? i.e. you're not also using some of tshering's 'Modifications for Bad Eyes' or pipcat's alternative nickel patcher, are you? If you were using multiple patching methods then it would be quite easy for each method to be wiping out the changes from the previous method.
   
2. Have you also enabled any of the other patches in GeoffR's nickel.patch file? If so are those patches working OK?
   
3. When you run 4.3.8842.bat can you confirm that the end of the console log looks something like the following - specifically the 5 red lines:

ETA: The 33% reduction patch is working for me. See attached screenshots from my H20. I haven't applied GeoffR's Custom Footer patch so you can see the difference in depth of the header and footer in the 2nd image.

Hey GeoffR. Thanks for your work on this.

Regarding 'Custom reading footer style', I'm flashing my H2O from 3.19.5761 to 4.3.8842. I previously used the following values to shrink the footer to my preferred height:

# Example replacement footer height values: AuraHD/H2O/GloHD
replace_string = 001A, `footerMargin: 105;`, `footerMargin: 170;`
replace_string = 002D, `min-height: 70px;`, `min-height: 36px;`
replace_string = 003F, `max-height: 70px;`, `max-height: 36px;`

However, 70px and 36px output an error in the latest patch. I've tried various other combinations and they all result in an error. Currently, I'm using the default values of

# Replacement footer height values: AuraHD/H2O/GloHD
replace_string = 0076, `min-height:80px`, `min-height:52px`
replace_string = 0086, `max-height:80px`, `max-height:52px`

The patch is nearly perfect except for the larger footer than I prefer. Geoff, or anyone else, are there smaller than default values that will output a usable patch?

I've not yet tried it, but here is my customized patch for the H2O.

# Multi-version patch: 4.0.7523 - 4.3.8842+
# patch_group = `Reading footer alternatives`
#
## This patch customises the following properties of the reading footer:
##
##  * Footer height (the amount of the screen reserved for the footer.)
##  * Caption font size (Caption = page number or other progress indicator)
##  * Caption top margin, which changes its vertical position within the footer.
##  * Caption font family.
#
# When editing the replacement values below, BE CAREFUL NOT TO CHANGE THE LENGTH
# OF THE REPLACEMENT STRING! If a replacement string is too long you will get
# an error when making the patch, but if one is too short then there will be no
# error, but strange things will happen to the reading footer.
