[PATCH][SMARTPHONE][TOUCHPAD] Mojo FPS Booster [2.x] [3.x]

[stu5797]

Thanks shifty!

[ShiftyAxel]

No worries, I found out that the 2.1.2 Veer frameworks are different to the 2.1.0 Pre2 etc frameworks, and for some reason there's no 2.1.2 option on the Preware submission form.
I've submitted a separate patch specifically for the veer. In the meantime, said patch is attached below

for 2.1.2
you want to update usr/palm/frameworks/mojo.core/submission/33/concatenated.js from your changes, and usr/palm/frameworks/mojo.core/submission/33mojo_core.js, and then usr/palm/frameworks/mojo/builtins/palmmojo_coreVersion1_0.js (almost same as 33mojo_core.js)

If you'll read the post in it's entirety, you'll notice that I've already updated the patch with that very change.

there're 2 patch relative to veer here, and i fail to see any changes to usr/palm/frameworks/mojo/builtins/palmmojo_coreVersion1_0.js, neither on the other 2 patches for other webos version. where is the patch i miss?

the patch you upload in later reply, is exactly the same as your first post in thread thread. something wrong with my browser? or did you upload the wrong file?

btw, i guess same files has to be patch for 2.* 3.*, not just veer

[ShiftyAxel]

None of the patches ever made changes to palmmojo_coreVersion1_0.js, there's nothing in there relating to Mojo's FPS or scrolling. And the Veer patch on the first post is identical to the one on page 2.
The Pre3, Touchpad and Veer all run mojo.core 33, whereas older devices such as Pre-/+, Pre2 and Pixi run mojo.core 32. I uploaded the Veer patch seperately because Preware doesn't have an option for webOS 2.1.2 (Veer) and I didn't want to cause confusion over the naming.

are you sure the changes take effect after the patch? i suggest you change the value to more strange so we can feel it really affect

when you want to change something like

Intriguing, I'll take a look into it. I do hate those massive chunks of unformatted javascript :|

[tboy2000]

what the heck is mojo? :-) Do I need this?

[ShiftyAxel]

Mojo is the framework which all the pre-touchpad webOS apps were written in. It's what provides stuff like menus, buttons etc. This patch will increase Mojo's Target FPS and Scroll Event Rate in order to make it smoother and nicer looking

I'm just this minute working on an update regarding the info moo.tinys posted, so if you want the newest version give me about 10 minutes :P either that or wait until it gets updated in preware (a few hours to a couple of days)

[ShiftyAxel]

Apologies for the double post, buuuut...

UPDATE!
Turns out, the patch's settings were being overridden by the ones in palmmojo_coreVersion.js and palmInitFramework and therefore it wasn't actually doing anything. Whoops. Thanks to moo.tinys for info on palmmojo_coreVersion.js.

The good news however, is that I've updated the patches with the new settings. The patches are now separated into webOS 1.4.5, 2.1, 2.2 and 3.x. (Yup, 1.4.5 is now supported. ) and have been submitted to Preware.

For those of you who want it now, the patches are attached below. I'll also update the OP and add them there.

EDIT: Updated again! iPhone smooth scrolling! See OP!

Does this negatively impact battery life significantly?

[ShiftyAxel]

I've been running it for the last few days and not noticed anything, but to be honest the best advice I can give is 'try it and see'.
