doRotate (hold magnifier) now rotates the screen thru all four (4) possible states,

If you want to use LD_PRELOAD you have at least to rewrite ebookEinkDoRotate ()

Tested with 1.4.00.23260

Mark, is there a file for 600 model?

[Mark Nord]

Kartu, not at the moment.
(Thought that it was done in boroda or amutin FW via JS, but can't find a reference now)

A quick check of the disassemblies shows that the 3 functions (eBook_rotate, ebookEinkDoRotate and ebookSubcpuDoRotate) are implementd in a different way for the 600 as for the 300/505.

The op-code is optimized, so there is not much space for patching.

Mark, all combinations of rotations are done via JS only on x50s.
I've tried to do doRotate 600 the same way, but it simply ignores params and toggles betwen 0 and 90 degrees.

Thinking of the implementation of the screensaver/standby pic, I doubt if ebook.so for PRS-600 is used anyway.

Here is code from defsked ebooksystem.so

Spoiler:

	<obj41> = new this.Object()
	this.ebook.device.framebuffer.orientation = <obj41>
	this.ebook.device.framebuffer.orientation.portrait = this.__xs__number.parse('0');
	this.ebook.device.framebuffer.orientation.landscape = this.__xs__number.parse('1');
	this.ebook.device.framebuffer.orientation.timer = null;
	this.ebook.device.framebuffer.orientation.onCallback = function () {
		var target, orientation;
		target = this.target;
		orientation = target.getCurrent();
		target.setCurrent((orientation == target.portrait)?target.landscape:target.portrait);
		target.timer.close();
		target.timer = null;
	};
	this.ebook.device.framebuffer.orientation.rotate = function () {
		var timer;
		if (!this.timer) {
			this.timer = new <global>.Timer();
		}
		else {
			this.timer.cancel();
		}
		timer = this.timer;
		timer.target = this;
		timer.onCallback = this.onCallback;
		timer.schedule(10);
	};
	this.ebook.device.framebuffer.orientation.setCurrent = this.@[63];
	this.ebook.device.framebuffer.orientation.getCurrent = this.@[64];
	this.ebook.device.framebuffer.orientation.reset = this.@[65];
	this.ebook.device.framebuffer.orientation;

Assuming that this.ebook.device.framebuffer.orientation.setCurre nt can handle all four states it may be worth to overload "this.ebook.device.framebuffer.orientation.rot ate" and try calling target.setCurrent() with params 2 and 3

[Edit] or even better just set this.ebook.device.framebuffer.orientation.landscap e to the desired value [/Edit]

Great findings, it should do the trick.

When ca we expect the flasher to be ready??? just askin

[VICTORSJG]

Kartu, are you going implement in the scripts of the games a localization for the name of these?

thanks

pd. for the script 505_core_zLang.js i have made a modification to change the icon for a earth globe, if i have time i'll send you.

[anyone]

What about the PRS-700. Did anyone do any work on this?

[kartu]

Victor, I have no plans for localizing games at the moment.

anyone, 700 is not supported, sorry.

Hi I was wondering, is there a chance for Greek Fonts support in PRS-505? It seems 505 is the only one that doesn't have support Greek alphabet yet. Is there a specific reason that makes it difficult? Thank you in advance.

Also can I somehow manually add Greek fonts support using your firmware?

[kartu]

Kast
Please check this.

Updated fonts will be released for 505 as well.

[Kast]

Thank you very, very much.

kartu can you please make the instructions more detailed for those of us not so smart people.

Wait for PRS+ base flashers. They will be straightforward to use.

not meaning to sound pushy but do you have an estimate date when it will come out?
