I noticed, that the very usefull touchscreen test included in firmware 1.0.0 and 1.0.1 don't work with fw 1.1.0 (or is it just me?).
Bug or intention, I don't know.
So I ripped the file from fw 1.1.0 (it's still there] and uploaded it to the archive.
Just unzip and copy it to your SD card. Now you can start it with the launcher and exit with L+R buttons.

This file is originally included with Noiz2sa from notaz.

With this file it is possible to reduce screen tearing and remove stutter on firmware 1.1.0 in many games.
Here's an example for Quake 2:

Download Noiz2a from the archive. Copy the file pollux_dpc_set to the Quake 2 folder.

Now edit q2.gpe:

#!/bin/sh

./cpufreq --freq 750
./pollux_dpc_set 'lcd_timings=397,1,37,277,341,0,17,337;clkdiv0=9'
./sdlquake2 +set vid_ref softsdl +set s_khz 22
#for a timedemo run add +set timedemo 1 +map demo1.dm2
cd /usr/gp2x/
./gp2xmenu

Add the line starting with ./pollux... to the wrapper script. Now the application runs with changed display timings to reduce tearing and stutter on firmware 1.1.0.
Do not change the values after lcd_timings exept you know what you're doing.
Use an Unix compatible editor like Notepad++.

With this solution there is no performance hit but possible shorter battery life. Only the display timings are changed.
The tearing is not complete eliminated with this, but I hardly noticed any tearing in Quake 2 or Noiz2sa.

Credits go to notaz and Exophase. Thanks guys!

BootMii configuration editor allows you to change the values in the /bootmii/bootmii.ini file without having to take out the SD card and edit it on a PC.

Version 2.0
Settings Dialog to change editor settings. This can be accessed by pressing the ‘HOME’ button. The settings are persisted to the langauges file, so if you change the language/skin, whenever you load BootMii Configuration Editor, your selected options will be the default
Internationalisation Supported (Currently English & Spanish Langauges available). Further langauges can be added by editing the bce_messages.xml file. See the readme.txt for details of how to do this
Please be careful if you do edit the XML file. A corrupt/non well-formed XML file
will result in a Crash of the Wii and will dump the stack to the screen.
Ensure you take a backup of the original before attempting to make any custom changes
Currently you can only use characters in the standard ASCII character set,
e.g. [0-9] [a-z] [A-Z] Some puncation characters may also cause issue
It is recommended that you do not use characters with any accents/umlauts/etc
as this will cause an issue
If you do create a translation for a new language please let me know and I’ll then include it in the next release!

Skins/Colour Change. The application can now be presented in a number of look & feels. Initially the following skins are available:
Windows - Windows Installer/DOS like look/feel with a blue background and grey windows
Console - Black background, white text with other colour text to highlight options/selections
Inverse Console - White background, black text with other colour text to highlight options/selections
Custom Skins can be added by editing the bce_messages.xml file. See the readme.txt for instructions on how to do this.

Online version Checking. When the Editor is loaded, it performs a check to see if the version running is the latest available version. If a newer version is available, then a message is shown for a few seconds during startup to indicate this. This online checking can be disabled if you do not wish BootMii Configuration Editor to check for a new version or do not have the wii networked. If you wish to disable this check, see the instructions in the readme.txt
Please be careful if you do edit the XML file. A corrupt/non well-formed XML
file will result in a Crash of the Wii and will dump the stack to the screen.
Ensure you take a backup of the original before attempting to make any custom changes.

I’m sorry for those of you who will be disappointed that I’m not posting to talk about Wii64 or WiiSX right now, but I have another little release I’d like to announce. A month or so ago, I was working on porting OpenJazz, a Jazz Jackrabbit 1 engine, to the Wii, and I got it in a pretty polished condition. However, I didn’t release it earlier because I couldn’t get the network support just right. I’ve decided to roll it out in its current state without networking and hopefully someone else interested in the project will pick it up because I’d like to focus more on Wii64. Anyone interested should check out: the google code page.
